The modular water treatment system was specially developed for the outpatient care sector. While retaining the overall geometry, the system can be adapted to the different degrees of water hardness in Germany, the quantities required in different outpatient centers, as well as to the initial water quality including any treatment steps on the part of the supplier. The modularity offers the decisive advantage that the overall concept can be adapted to the respective water type or composition as well as the treatment process of the supplier. Concept Demineralized water treatment for the outpatient sector Use of demineralized water in the outpatient sector Fully demineralized water (demineralized water) plays a central role in the outpatient medical sector, particularly in the reprocessing of medical devices, in laboratory applications and in the final rinse for mechanical instrument reprocessing. The aim is to avoid residues that could be caused by minerals, salts or other substances contained in tap water. For safe use, demineralized water must meet defined quality requirements: The conductivity must be below 0.1 µS/cm. This indicates that it contains almost no dissolved salts or ions. The silicate content must not exceed 0.4 g/l to avoid silicate deposits on medical instruments that could impair functionality or lead to hygienic risks. Only if these limit values are adhered to can residue-free and gentle reprocessing be guaranteed that meets the hygiene requirements in the outpatient sector. This is particularly relevant in dental practices, dermatology, endoscopy and in outpatient operating theatres, where deionized water is used for final rinsing or for steam generators in sterilization processes, among other things. The components used are listed below: Cabinet System separator Filter system (pre-filter & activated carbon filter) Softening system Reverse osmosis system Permeate tank 100 liters (volume can be adjusted) Pressure boosting station Two-stage mixed bed UV system (optional) Pyrogen filter (optional) Ring line in front of the mixing bed if the consumers are not removed to prevent contamination Brine lifting system (optional) Testomat 808 SIO2 (silicate measurement) Conductivity measurement NeoTecMaster (optional) Performance of the system Depending on the design of the system, 90 l, 150 l, 230 l or 300 l deionized water can be produced per hour. The capacity of the permeate tank can be adjusted, but must be positioned outside the cabinet due to the larger dimensions including the pressure booster station from a capacity of > 150 l/ (depending on the application). Shut-off via system separator The installation of a system separator is mandatory to protect the drinking water network from contamination by treated water or changes to the natural composition of the drinking water fed in due to its technical treatment. The system has an integrated system separator (type BA), which is located directly behind the Aqua-Stop of the water connection. Aqua-Stop (solenoid valve shut-off) An Aqua-Stop is a safety mechanism used in water supply systems to stop or limit the flow of water if a fault or leakage occurs. The Aqua-Stop is located directly behind the main water connection of the system as the first element. The associated solenoid valve is coupled with two sensors, one of which is integrated in the bottom tray of the cabinet and the second is located outside at the level of the tank and the pressure booster station. Filter The pre-filter section is a filter unit consisting of a pre-filter and an activated carbon filter. Its main purpose is to protect downstream softening and osmosis systems that could be damaged by impurities in the water. Water softener The water softener removes the hardness constituents (calcium and magnesium) from the drinking water and replaces them with sodium. The function is based on an ion exchange process and ensures that the reverse osmosis membranes are reliably protected against clogging. Reverse osmosis In reverse osmosis, the natural osmotic process is reversed. The softened water is pumped through a membrane under pressure, whereby the membrane only allows water molecules and very small molecules to pass through and retains larger particles such as salts, bacteria, fours and other impurities. The installed reverse osmosis has a retention rate of approx. 98% in relation to all substances dissolved in the water. Permeate tank The built-in round tank offers advantages in terms of stability, cleaning and space requirements. The uniform shape ensures that the water is treated and stored efficiently. The optimized tank geometry prevents the potential growth of microbiological contamination and thus meets the high requirements for media purity to a greater extent. Pressure booster station The pressure booster station ensures that the connected consumers are supplied with the required operating pressure and flow rate. This enables an optimized and needs-based media supply. Mixing bed The two-stage mixing bed (connected in series) is a so-called pole mixer. Due to the special composition of the resin contained in the cartridges, all dissolved substances remaining in the water are reliably removed. The resin used is highly effective against silicates, which have a particularly negative impact on the reprocessing of medical products. The mixing bed is also the first stage of the recirculation process when using the optionally available buffer tank system. Pyrogen filter A pyrogen filter is a special type of filter used in water treatment to remove pyrogens from the water. Pyrogens are substances that can cause an immunological reaction in the body, in particular an increase in body temperature. These are usually endotoxins that are released by bacteria such as Escherichia coli (E. coli). Water disinfection by UV irradiation The development of water disinfection using UV radiation has made considerable progress in recent years due to its simplicity and efficiency. The UV-C rays generated, which are significantly more intense than sunlight, are therefore used to disinfect water in order to counteract water contamination. They enable the removal of legionella, microbes, bacteria, viruses and protozoa while respecting the environment. Testomat® 808 SiO2 silicate measuring device A Testomat®808 SiO2 silicate is used for permanent silicate monitoring. The Testomat®808 SiO2 is a measuring instrument that is used to determine the silicate content in water. The use of the Testomat 808®SiO2 ensures reliable compliance with the limit value for SiO2 of 0.4 mg/l recommended by the DGSV and AKI. Conductivity measurement Continuous monitoring of conductivity in the range of 0-10 μS/cm on the second mixing bed. For the reprocessing of medical devices, a conductivity of <1 µS/cm is recommended for the water used for the cleaning & disinfection and sterilization process. The conductivity measurement used continuously monitors whether the conductivity falls below this value. NeoTecMaster® 5 inch with housing Data acquisition, visualization and processing are just some of the relevant topics in the field of modern water treatment. The networking of different measuring systems and their integration into process automation is an elementary component here. The NeoTecMaster® was specially developed for this task and is a manufacturer-independent multi-parameter system. Cabinet systems Only a minimum footprint of 1.60 m x 1 m is required for installation. The module consists of 2 cabinets, each 80 cm wide and 60 cm deep. It is possible to work with double hinged doors, resulting in a room depth of 1m due to the depth of 60cm and a double hinged door with a dimension of 40cm. The cabinets used are made of sturdy sheet steel modules and have a high-quality surface coating. Viewing window Viewing windows are installed in Rittal enclosures to provide an overview of the measurement technology. The use of viewing windows in Rittal enclosure systems has several advantages. They enable a visual inspection of the devices in the enclosure without having to open the enclosure. This facilitates the monitoring, maintenance and troubleshooting of components without compromising the integrity of the enclosure. The viewing windows are usually made of a transparent material such as glass. Notes: Viewing windows in Rittal enclosures are only available for single-leaf doors. If this option is selected, please note that the required minimum room depth increases from 100 cm to 140 cm.Abwasser Abführung über Solehebeanlage (optional) As an optional component, the treatment plant can be extended to include an integrated wastewater lifting unit, which pumps the generated and collected wastewater into the sewer system. The main wastewater volume flows here are the wastewater from the regeneration of the softening system and the concentrate from the reverse osmosis. Collecting tray The integrated drip tray is used to detect leaks and is therefore a safety device part of the cabinet systems.The optional components of the system:Viewing windowLighting Frequently Asked Questions For which facilities is the system intended?

Yes, it has been specifically developed for outpatient facilities such as ophthalmology practices, surgical centres, etc. Can the system be adapted to my water quality? Yes, the system can be flexibly adapted to different water parameters and requirements. How clean is the water after treatment? After treatment, the water is classified as fully demineralised water (DE water) and thus meets very strict quality requirements for the outpatient medical sector. In concrete terms, this means: the conductivity is below 0.1 µS/cm, meaning that the water contains virtually no dissolved salts or ions. In addition, the silicate content must not exceed 0.4 g/l to reliably prevent deposits on medical instruments. Thanks to this high purity, the water is residue-free and gentle on materials, making it particularly suitable for the reprocessing of medical devices, laboratory applications and the final rinse during automated instrument reprocessing. This water quality is crucial for hygienically safe processes, particularly in sectors such as dental practices, dermatology, endoscopy and outpatient surgical centres. How much water can the system supply per hour? Depending on the model, it produces between 90 and 300 litres of deionised water per hour. Does the system protect against germs and contaminants? Yes, several stages, such as filters and UV purification, ensure very high water quality. Do I need a lot of space for installation? No, the system requires only a compact footprint and fits into many utility rooms. How do I keep an eye on the water quality? Measuring systems monitor the values automatically and display them clearly. Can I expand or adapt the system later? Yes, thanks to its modular design, the system can be adapted to new requirements at any time. Does the system support me in day-to-day operation? Yes, it operates largely automatically and relieves you of many manual tasks.

The benefits of NeoDeWa NeoDeWa from HeylNeomeris is a modular water treatment system specifically designed to supply deionised water for the reprocessing of sterile goods in outpatient facilities. Adaptability is key: each system is tailored to the specific conditions at the installation site. The design takes into account the existing water quality, the water’s hardness level and the actual water demand. Similarly, any treatment steps already carried out by the water supplier can be factored into the planning. The benefits of NeoDeWa: Design tailored to the existing water quality Sizing based on actual water demand Suitable for use with different levels of water hardness Modular design for a configuration tailored to your needs Compact design retained even with customised configurations The result is a water treatment system tailored to the requirements of your outpatient treatment centre. Deionised water treatment for outpatient care Why is deionised water needed? Fully deionised water – or deionised water for short – plays a key role in the reprocessing of instruments and medical devices. It is used, amongst other things, to supply RDGs and Steris in instrument reprocessing, as well as in laboratory applications. During reprocessing, minerals, salts and other undesirable substances are removed from the water. This reduces residues and deposits on instruments and equipment and supports a process that is gentle on materials and hygienically safe. Typical areas of application for deionised water include: outpatient surgical centres dental practices dermatology clinics endoscopy centres other facilities carrying out instrument reprocessing Reliably monitoring water quality Consistently high water quality is particularly important when reprocessing medical devices. For this reason, key water parameters can be continuously monitored. The focus here is on conductivity and silicate content. Both values provide information about the quality of the treated water and help to prevent residues and deposits. The NeoDeWa concept The NeoDeWa water treatment plant combines all the necessary treatment stages into a single modular system. Pre-filtration, water softening, reverse osmosis, advanced treatment and water quality monitoring all work together as coordinated components. Depending on the requirements of the specific facility, the system can be individually configured and supplemented with additional components. Components of the NeoDeWa water treatment system Depending on the configuration, the system comprises: A system separator to protect the drinking water network Pre-filters and activated carbon filters for pre-treatment Water softener to reduce water hardness Reverse osmosis system, which removes the majority of dissolved substances Permeate tank with a capacity of 100, 200 or 300 litres Pressure boosting station for a reliable supply Two-stage mixed-bed system for further treatment Conductivity measurement to monitor water quality Testomat® 808 SiO₂ for monitoring the silicate content Circulation loop that keeps the water circulating when there is no consumption by users In addition, the system is optionally available with: Aqua-Stop and drip tray UV system Pyrogen filter Brine pumping system NeoTecMaster Your benefit: a fully integrated system With the NeoDeWa VE water treatment system, outpatient facilities do not receive a hodgepodge of individual components, but a system in which every element is perfectly coordinated – all from a single source: HeylNeomeris. Thanks to its modular design, the system can be adapted to water quality, water demand and the specific requirements of the facility. At the same time, key parameters remain under control and additional functions can be integrated as required. The result is a compact, tailor-made solution that reliably supplies deionised water in outpatient settings. NeoDeWa Water Treatment System – Flexible capacity for varying requirements The NeoDeWa water treatment system is tailored to the deionised water requirements of the respective facility. Depending on the model, the following capacities are available: 90 litres per hour 150 litres per hour 230 litres per hour 300 litres per hour The permeate tank is also selected to match the required water volume. If the capacity exceeds 150 litres per hour, the permeate tank and pressure-boosting station are usually placed outside the cabinet system due to their dimensions. The specific configuration depends on the local conditions. Compact and space-saving The main priority for the cupboard system was to minimise the space required. A floor area of 1.60 m × 1.00 m is sufficient for both cupboards. Each cabinet measures 80 cm in width and 60 cm in depth. As the double-leaf doors take up hardly any extra space when opened, the system is also suitable for rooms where space is at a premium. Robust and designed for daily use The cabinets are manufactured from sturdy sheet steel and feature a high-quality, durable surface coating. The NeoDeWa cabinet system thus combines flexible performance, compact dimensions and a robust construction in a solution tailored to the specific application. Shut-off via a system separator To ensure that drinking water quality is not compromised, treated water must not flow back into the drinking water supply. A system separator is therefore mandatory. The system comes fitted with a Type BA system separator as standard. It is positioned immediately behind the optionally available Aqua-Stop on the water connection and safely isolates the drinking water mains from the system. Testomat® 808 SiO₂ silicate analyser A Testomat® 808 SiO₂ silicate analyser is used for continuous silicate monitoring. This analyser determines the silicate content in the water. This ensures that the limit value of 0.4 mg/l for SiO₂, as recommended by the DGSV and AKI, is reliably adhered to. Conductivity measurement The integrated conductivity measurement continuously monitors the range of 0–10 µS/cm at the second mixed-bed stage. A conductivity of < 1 µS/cm is recommended for cleaning, disinfection and sterilisation processes involving medical devices – the system continuously checks that this value is not exceeded. Filter systems The pre-filter section consists of a pre-filter and an activated carbon filter. Its primary function is to protect the downstream water softener and reverse osmosis system, which could be damaged by impurities in the water. Water Softener The water softener removes the hardness-causing elements calcium and magnesium from the drinking water and replaces them with sodium. This is based on an ion-exchange process that reliably prevents the reverse osmosis membranes from becoming blocked. Reverse Osmosis Reverse osmosis reverses the natural osmotic process: The softened water is forced under pressure through a membrane that allows only water molecules and very small molecules to pass through. Larger particles such as salts, bacteria, viruses and other impurities are retained. The reverse osmosis system installed achieves a retention rate of around 98 per cent, based on all dissolved substances in the water. Permeate tank The cylindrical tank used offers advantages in terms of stability, ease of cleaning and space requirements. Its uniform shape ensures efficient treatment and storage of the water. The optimised tank geometry prevents the build-up of microbiological contamination and thus meets the high standards for media purity to a particularly high degree. Pressure-boosting station The pressure-boosting station supplies the connected consumers with the necessary operating pressure and flow rate. This ensures an optimised and demand-driven supply of media. Two-stage mixed-bed filter The two-stage mixed-bed filter, connected in series, acts as a polisher. The resin in the cartridges is formulated to reliably remove all dissolved substances still present in the water. It is particularly effective against silicates, which have a particularly adverse effect on the processing of medical devices. At the same time, the mixed-bed forms the first stage of the recirculation process when the optionally available buffer tank system is used. Aqua-Stop (solenoid valve shut-off) – Option The Aqua-Stop is a safety device in water supply systems that stops or limits the flow of water in the event of a fault or leak. It is positioned as the first component directly behind the system’s main water connection. The associated solenoid valve operates using two sensors: one is located in the cabinet’s base tray, whilst the second is situated outside, at the same level as the tank and the pressure-boosting station. The integrated drip tray detects leaks and, as a safety feature, forms an integral part of the cabinet systems in combination with the Aqua-Stop. UV system for water disinfection – optional Water disinfection using UV irradiation has advanced significantly in recent years because it is both simple and efficient. The UV-C rays generated are considerably more intense than sunlight and are used to disinfect the water in order to prevent bacterial contamination. Legionella, microbes, bacteria, viruses and protozoa can be removed in an environmentally friendly manner. Pyrogen filter – optional The pyrogen filter is a specialised type of filter used in water treatment to remove pyrogens from the water. Pyrogens can trigger an immunological reaction in the body, in particular a rise in body temperature. These are usually endotoxins released by bacteria such as Escherichia coli (E. coli). Wastewater discharge via brine lifting system – option As an option, the treatment plant can be expanded to include an integrated wastewater lifting system, which conveys the generated and collected wastewater into the sewerage system. The main wastewater flow streams are the regeneration wastewater from the water softener and the concentrate from the reverse osmosis system. NeoTecMaster® 5-inch with housing – Option Data acquisition, visualisation and processing are central aspects of modern water treatment. A fundamental component of this is the networking of a wide variety of measurement systems and their integration into process automation. The NeoTecMaster® – a manufacturer-independent multi-parameter system – was developed precisely for this purpose.

The benefits of NeoDeWa With NeoDeWa, HeylNeomeris offers a modular water treatment system designed to supply deionised water for the reprocessing of sterile medical devices in outpatient facilities. The key factor is its flexible design: each system is tailored to the on-site conditions. This takes into account the existing water quality, the degree of hardness and the actual water demand. Treatment steps already carried out by the water supplier are also factored into the planning. NeoDeWa offers the following benefits: Configuration tailored to the existing water quality Capacity tailored to actual consumption Suitable for different levels of water hardness Modular design for a customised configuration Compact design even with customised configurations This provides you with a water treatment system that is precisely tailored to the requirements of your outpatient treatment centre. Deionised water treatment for outpatient care Why is deionised water required? Fully deionised water, or deionised water for short, is essential for the reprocessing of instruments and medical devices. It is used, for example, to supply RDGs and Steris in instrument reprocessing, as well as in laboratory settings. During the reprocessing process, minerals, salts and other undesirable components are removed from the water. This reduces residues and deposits on instruments and equipment, thereby promoting a process that is gentle on materials and hygienically safe. Deionised water is typically used in: outpatient surgical centres dental practices dermatology clinics endoscopy centres other facilities carrying out instrument reprocessing Reliably monitoring water quality When treating medical devices, it is essential to maintain a consistently stable water quality. For this reason, the key water parameters can be monitored continuously. Conductivity and silicate content are particularly important. They indicate the quality of the treated water and help to prevent residues and deposits. The NeoDeWa Concept In the NeoDeWa water treatment system, all the necessary treatment stages are combined into a single modular system. From pre-filtration through softening and reverse osmosis to further treatment and quality monitoring, all components work together in a coordinated manner. Depending on the facility’s requirements, the system can be customised and expanded with additional components at any time. Components of the NeoDeWa water treatment system Depending on the model, these include: System isolator to protect the drinking water network Pre-filters and activated carbon filters for pre-treatment Water softener to reduce water hardness Reverse osmosis system, which retains the vast majority of dissolved substances Permeate tank with a capacity of 100, 200 or 300 litres Pressure-boosting station to ensure a reliable supply Two-stage mixed-bed system for further treatment Conductivity measurement to monitor water quality Testomat® 808 SiO₂ to monitor the silicate content A loop line that keeps the water circulating when there is no draw-off The following are also available as options: Aqua-Stop and drip tray UV system Pyrogen filter Brine pumping system NeoTecMaster Your benefit: A fully integrated system The NeoDeWa reverse osmosis water treatment system provides outpatient facilities not with a loose collection of individual components, but with a fully integrated water treatment system – all from a single source: HeylNeomeris. Thanks to its modular design, the system adapts to water quality, water demand and the specific requirements of the facility. At the same time, key parameters are monitored, and additional functions can be added as required. The result is a compact, tailor-made solution for the reliable supply of deionised water in outpatient settings. NeoDeWa Water Treatment System – Flexible capacity for varying requirements The NeoDeWa water treatment system is tailored to the deionised water requirements of the respective facility. Depending on the model, the following capacities are available: 90 litres per hour 150 litres per hour 230 litres per hour 300 litres per hour Similarly, the permeate tank is sized to accommodate the required water volume. Where the flow rate exceeds 150 litres per hour, the permeate tank and pressure-boosting station are usually located outside the cabinet system due to their size. The specific design of the system is determined by the conditions at the installation site. Compact and space-saving When developing the cabinet system, the focus was on minimising the space required. Both cabinets can be installed within an area of 1.60 m × 1.00 m. Each cabinet is 80 cm wide and 60 cm deep. As the double-leaf doors require very little space when opened, the system can also be accommodated where space is limited. Robust and designed for daily use The cabinets are made of sturdy sheet steel and feature a high-quality, durable surface coating. The NeoDeWa cabinet system thus combines flexible performance, compact dimensions and a robust design to create a solution tailored to the specific application. Shut-off via system isolator Treated water must not be allowed to flow back into the drinking water supply, as this would compromise drinking water quality. A system isolator is therefore mandatory. A Type BA system isolator is already integrated into the system. It is positioned directly behind the optionally available Aqua-Stop on the water connection and reliably isolates the system from the drinking water mains. Testomat® 808 SiO₂ silicate analyser Continuous silicate monitoring is carried out by a Testomat® 808 SiO₂ silicate analyser. The device determines the silicate content of the water and ensures that the SiO₂ limit of 0.4 mg/l recommended by the DGSV and AKI is reliably adhered to. Conductivity measurement At the second mixed-bed unit, the integrated conductivity measurement continuously monitors the range from 0–10 µS/cm. For water used in the cleaning, disinfection and sterilisation processes of medical devices, a conductivity of < 1 µS/cm is recommended. The measurement continuously monitors whether the value remains below this threshold. Filter systems The pre-filter section consists of a pre-filter and an activated carbon filter. Its main function is to protect the downstream water softener and reverse osmosis system, which could be damaged by impurities in the water. Water softener In the water softener, the hardness-causing elements calcium and magnesium are removed from the drinking water and replaced with sodium. The underlying ion-exchange process reliably protects the reverse osmosis membranes from blockages. Reverse osmosis Reverse osmosis reverses the natural osmotic process: Softened water is forced under pressure through a membrane that allows only water molecules and very small molecules to pass through. Salts, bacteria, viruses and other larger particles are retained. The built-in reverse osmosis system achieves a retention rate of around 98 per cent for all dissolved substances in the water. Permeate tank The built-in cylindrical tank offers outstanding stability, ease of cleaning and a compact footprint. Its uniform shape enables efficient treatment and storage of the water. Furthermore, the optimised tank geometry prevents the growth of microbiological contamination, thereby meeting the high standards for media purity to a particularly high degree. Pressure-boosting station The pressure-boosting station provides the required operating pressure and flow rate for the connected consumers. This enables an optimised and demand-driven supply of media. Two-stage mixed-bed system The two-stage mixed-bed system, connected in series, acts as a polisher. The special composition of the resin in the cartridges ensures that all substances still present in solution are reliably removed from the water. The resin is highly effective against silicates, which have a particularly detrimental effect on the processing of medical devices. If the optionally available buffer tank system is used, the mixed-bed unit also forms the first stage of the recirculation process. Aqua-Stop (solenoid valve shut-off) – Option The Aqua-Stop is a safety mechanism for water supply systems that interrupts or restricts the flow of water in the event of a fault or leak. It is installed as the first component immediately after the system’s main water connection. The associated solenoid valve is linked to two sensors: one in the base tray of the cabinet, the other outside at the level of the tank and pressure-boosting station. The integrated drip tray is designed to detect leaks. As a safety feature, it forms part of the cabinet system in conjunction with the Aqua-Stop. UV system for water disinfection – optional UV irradiation for water disinfection has made significant progress in recent years, as it is both straightforward and efficient. The UV-C rays generated are significantly more intense than sunlight and are used to disinfect the water in order to prevent bacterial contamination. Legionella, microbes, bacteria, viruses and protozoa are eliminated in an environmentally friendly manner. Pyrogen filter – Option The pyrogen filter is a specialised water treatment filter that removes pyrogens from the water. Pyrogens trigger immunological reactions in the body, primarily an increase in body temperature. These are usually endotoxins released by bacteria such as Escherichia coli (E. coli). Wastewater discharge via brine lifting system – option As an option, the treatment plant can be supplemented with an integrated wastewater lifting system, which pumps the wastewater produced and collected into the sewerage system. The largest wastewater flow rates arise from the regeneration of the water softener and the concentrate from the reverse osmosis system. NeoTecMaster® 5-inch with housing – Option Data acquisition, visualisation and processing are among the key tasks of modern water treatment. A key aspect of this is networking a wide variety of measurement systems and integrating them into process automation. The NeoTecMaster® – a manufacturer-independent multi-parameter system – was designed precisely for this purpose.

The benefits of NeoDeWa NeoDeWa from HeylNeomeris is a modular water treatment system that supplies deionised water for the reprocessing of sterile medical devices in outpatient facilities. The key factor is the bespoke design: each system is tailored to local conditions – the existing water quality, the degree of hardness and the actual volume of water required. The planning process also takes into account which treatment steps are already carried out by the water supplier. This is what NeoDeWa offers you: Configuration tailored to the existing water quality Capacity designed according to actual consumption Suitable for use with different levels of water hardness Modular system for a customised configuration Compact dimensions despite individual configuration The result is a water treatment system that is precisely tailored to the requirements of your outpatient reprocessing centre. Deionised water treatment for outpatient care Why is deionised water required? Without deionised water – or ‘VE’ water for short – instruments and medical devices cannot be reprocessed in accordance with standards. It is used, amongst other things, to supply RDGs and Steris in instrument reprocessing, as well as in laboratories. During the treatment process, minerals, salts and other undesirable components are removed from the water. This reduces the occurrence of deposits and residues on instruments and equipment – which protects the materials and supports a hygienically safe process. Typical areas of application for deionised water include: outpatient surgical centres dental practices dermatology clinics endoscopy centres other facilities with instrument reprocessing Reliably monitoring water quality The reprocessing of medical devices requires a consistently high standard of water quality. The relevant water parameters can therefore be monitored continuously. The focus here is on conductivity and silicate content. Both values provide information about the quality of the treated water and help to prevent deposits and residues. The NeoDeWa concept The NeoDeWa water treatment plant combines all the necessary treatment stages into a single modular system. Pre-filtration, water softening, reverse osmosis, further treatment and quality monitoring all work together seamlessly. The configuration is tailored to the facility’s requirements and can be expanded with additional components at any time. Components of the NeoDeWa water treatment system Depending on the model, the system comprises: A system separator to protect the drinking water network Pre-filters and activated carbon filters for pre-treatment Water softener to reduce water hardness Reverse osmosis system, which retains the majority of dissolved substances Permeate tank with a capacity of 100, 200 or 300 litres Pressure boosting station for a reliable supply Two-stage mixed-bed system for further treatment Conductivity measurement to monitor water quality Testomat® 808 SiO₂ for monitoring the silicate content Circulation loop that keeps the water circulating when there is no draw-off The following optional extras are available: Aqua-Stop and drip tray UV system Pyrogen filter Brine pumping system NeoTecMaster Your benefit: A fully integrated system With the NeoDeWa VE water treatment system, outpatient facilities do not receive a hodgepodge of individual components, but a water treatment system that is fully coordinated from start to finish – all from a single source: HeylNeomeris. The modular design tailors the system to water quality, water demand and the specific requirements of the facility. Key parameters remain under control, whilst additional functions can be retrofitted as required. This results in a compact, tailor-made solution for a reliable supply of deionised water in outpatient settings. NeoDeWa water treatment system – Flexible capacity to meet a range of requirements The capacity of the NeoDeWa water treatment system is determined by the facility’s deionised water requirements. Depending on the model, the following capacity options are available: 90 litres per hour 150 litres per hour 230 litres per hour 300 litres per hour The permeate tank is also determined by the required water volume. For capacities exceeding 150 litres per hour, the permeate tank and pressure-boosting station are usually housed outside the cabinet system due to their dimensions. The specific configuration of the system depends on the conditions at the installation site. Compact and space-saving The main priority for the cupboard system was to minimise the space required. A floor area of 1.60 m × 1.00 m is sufficient for both cupboards. Each cabinet measures 80 cm in width and 60 cm in depth. As the double-leaf doors barely swing out when opened, the system can be accommodated even in confined spaces. Robust and designed for everyday use The cabinets are made from sturdy sheet steel and feature a high-quality, durable surface coating. The NeoDeWa cabinet system thus combines flexible performance, a small footprint and a robust construction to provide a solution for any application. Isolation via a system separator If treated water flows back into the drinking water supply, the quality of the drinking water is compromised – a system separator is therefore mandatory. The system is already fitted with an integrated BA-type system separator. It is located directly behind the optionally available Aqua-Stop on the water connection and reliably isolates the system from the drinking water mains. Testomat® 808 SiO₂ silicate analyser A Testomat® 808 SiO₂ silicate analyser ensures continuous silicate monitoring. It measures the silicate content of the water and ensures that the SiO₂ limit of 0.4 mg/l recommended by the DGSV and AKI is reliably adhered to. Conductivity measurement The integrated conductivity measurement on the second mixed-bed continuously monitors the range from 0–10 µS/cm. A conductivity of < 1 µS/cm is recommended for the cleaning, disinfection and sterilisation processes of medical devices. The measurement continuously checks whether this value is being maintained. Filter systems The pre-filter stage consists of a pre-filter and an activated carbon filter. Their primary function is to protect the downstream water softener and reverse osmosis system, which can be damaged by impurities in the water. Water Softener The water softener removes the hardness-causing minerals calcium and magnesium from the drinking water and replaces them with sodium. This ion-exchange process reliably protects the reverse osmosis membranes from blockages. Reverse Osmosis Reverse osmosis reverses the natural osmotic process: softened water is forced under pressure through a membrane that allows only water molecules and very small molecules to pass through. Salts, bacteria, viruses and larger particles are retained. In terms of all dissolved substances in the water, the built-in reverse osmosis system achieves a retention rate of around 98 per cent. Permeate tank The cylindrical tank used offers advantages in terms of stability, ease of cleaning and space requirements. Its uniform shape allows for efficient treatment and storage of the water. The optimised tank geometry also prevents the growth of microbiological contamination, thereby meeting the high standards required for media purity. Pressure-boosting station The pressure-boosting station supplies the operating pressure and flow rate required by the connected consumers. This ensures an optimised and demand-driven supply of media. Two-stage mixed-bed system The two-stage mixed-bed system, connected in series, acts as a polisher. Thanks to the special resin composition in the cartridges, all remaining dissolved substances are reliably removed from the water. The resin is particularly effective against silicates, which have the greatest adverse effect on the reprocessing of medical devices. If the optionally available buffer tank system is used, the mixed-bed unit also handles the first stage of the recirculation process. Aqua-Stop (solenoid valve shut-off) – Option The Aqua-Stop is a safety mechanism for water supply systems: in the event of a fault or leak, it interrupts or restricts the water flow. It is installed as the first component directly behind the system’s main water connection. Two sensors control the associated solenoid valve – one in the base tray of the cabinet, the second outside at the level of the tank and pressure-boosting station. The integrated drip tray detects leaks. Together with the Aqua-Stop, it forms part of the cabinet system’s safety features. UV water disinfection system – optional UV disinfection technology has advanced significantly in recent years, as it is both simple and effective. The UV-C rays generated are considerably more intense than sunlight and disinfect the water to prevent bacterial contamination. Legionella, microbes, bacteria, viruses and protozoa are eliminated in an environmentally friendly manner. Pyrogen filter – option A pyrogen filter is a specialised water treatment filter that removes pyrogens from the water. Pyrogens trigger immunological reactions in the body – primarily a rise in body temperature. In most cases, these are endotoxins released by bacteria such as Escherichia coli (E. coli). Wastewater discharge via brine lifting system – Option As an option, the treatment plant can be expanded to include an integrated wastewater lifting system, which conveys the generated and collected wastewater into the sewerage system. The largest wastewater flow rates originate from the regeneration of the water softener and the concentrate from the reverse osmosis system. NeoTecMaster® 5-inch with housing – option Collecting, visualising and processing data are among the core tasks of modern water treatment. The networking of a wide variety of measurement systems and their integration into process automation plays a key role in this. The NeoTecMaster® – a manufacturer-independent multi-parameter system – was developed precisely for this purpose.

The benefits of NeoDeWa NeoDeWa from HeylNeomeris is a modular water treatment system designed to supply deionised water for the reprocessing of sterile medical devices in outpatient facilities. The focus is on bespoke design: every NeoDeWa system is tailored to local conditions and actual requirements. Factors such as the existing water quality, the water’s hardness and the required water volume are all taken into account in the planning. Any existing treatment stages carried out by the water supplier are also considered. Your benefits with NeoDeWa: Customised configuration according to the existing water quality System capacity tailored to actual water requirements Suitable for different levels of water hardness Flexible modular system for a customised configuration Compact design despite individual configuration The result is a water treatment system that is precisely tailored to the requirements of your outpatient treatment centre – efficient, space-saving and tailored to your needs. Deionised water treatment for outpatient care Why is deionised water required? Deionised water plays a vital role in the standard-compliant reprocessing of instruments and medical devices. Among other things, it is used to supply cleaning and disinfection units (CDUs) and sterilisers in instrument reprocessing and in laboratories. During complete desalination, minerals, salts and other undesirable substances in the water are largely removed. This helps to reduce deposits and residues on instruments and equipment. It helps to protect materials and creates the conditions necessary for a hygienically safe reprocessing process. Typical areas of application for deionised water include: outpatient surgical centres dental practices dermatology clinics endoscopy centres other facilities with their own instrument reprocessing units Reliable monitoring of water quality Consistently high water quality is a key aspect of the reprocessing of medical devices. Relevant water parameters can therefore be monitored continuously. This enables changes in water quality to be detected at an early stage and the reprocessing to be reliably controlled. Conductivity and silicate content are central to quality monitoring. Both parameters provide important indications of the quality of the treated water and help to reduce deposits and residues on instruments and equipment. The NeoDeWa Concept The NeoDeWa water treatment system combines all necessary treatment steps into a single modular system. Pre-filtration, softening, reverse osmosis, further treatment and quality monitoring are optimally coordinated. The components used depend on the local water quality, the actual water demand and the individual requirements of the facility. Thanks to its modular design, the system can also be expanded with additional components at any time. Components of the NeoDeWa water treatment system Depending on the specific design, the system may comprise the following components: System isolator to protect the drinking water network Pre-filters and activated carbon filters for targeted pre-treatment of the water Water softener to reduce water hardness Reverse osmosis system to remove the majority of dissolved substances from the wa-ter Permeate tank with a capacity of 100, 200 or 300 litres Pressure-boosting station for a reliable water supply Two-stage mixed-bed system for further treatment Conductivity measurement for continuous monitoring of water quality Testomat® 808 SiO₂ for monitoring the silicate content Circulation loop for circulating the water when there is no draw-off In addition, the system can be optionally expanded, for example to include: Aqua-Stop and drip tray UV system Pyrogen filter Brine pumping system NeoTecMaster Your benefit: a fully integrated system With NeoDeWa, outpatient facilities do not receive a system made up of unconnected individual components, but a holistically planned and fully integrated water treatment system – supplied entirely from a single source by HeylNeomeris. The modular design allows for precise adaptation to the existing water quality, individual water requirements and the specific needs of the facility. At the same time, the key water parameters remain reliably under control. Additional functions and components can be retrofitted as required. The result is a compact, flexible and tailor-made solution for a reliable deionised water supply in the outpatient sector. NeoDeWa Water Treatment System – Flexible capacity for varying requirements The capacity of the NeoDeWa water treatment system is tailored individually to the deionised water requirements of the respective facility. Various capacity levels are available for this purpose: 90 litres per hour 150 litres per hour 230 litres per hour 300 litres per hour The size of the permeate tank is also selected according to the required water volume. For systems with a capacity of more than 150 litres per hour, the permeate tank and pressure-boosting station are usually installed outside the cabinet system due to their dimensions. The specific configuration used depends on the conditions at the installation site. Compact and space-saving During the development of the cabinet system, particular emphasis was placed on minimising the space required. Together, the two cabinets require a footprint of just 1.60 m × 1.00 m. With a width of 80 cm each and a depth of 60 cm, the system can be used even where space is limited. The double-leaf doors swing out only slightly when opened, thereby facilitating access to the components. Robust for day-to-day use The cabinets are made of sturdy sheet steel and feature a high-quality, durable surface coating. This ensures that the cabinet system is designed for daily use in outpatient settings. NeoDeWa combines performance tailored to specific needs, compact dimensions and a robust design in a harmoniously integrated system. Integrated system separator to protect the drinking water supply A system separator is required to prevent treated water from flowing back into the drinking water supply. NeoDeWa already features an integrated Type BA system separator. This is located directly behind the optionally available Aqua-Stop at the water connection and ensures a secure separation between the water treatment system and the drinking water supply. Testomat® 808 SiO₂ for monitoring the silicate content The Testomat® 808 SiO₂ continuously monitors the silicate content of the treated water. This allows you to check whether the SiO₂ limit of 0.4 mg/l recommended by the DGSV and AKI is being adhered to. Continuous measurement provides transparency regarding an important water quality parameter and helps to identify potential problems caused by an elevated silicate content at an early stage. Continuous conductivity measurement The integrated conductivity measurement system on the second mixed-bed unit continuously monitors water quality within a measurement range of 0–10 µS/cm. A conductivity of < 1 µS/cm is recommended for the processing of medical devices. Continuous measurement enables immediate verification that this range is being maintained. Filter systems for reliable pre-treatment The pre-filter section consists of a pre-filter and an activated carbon filter. Both components serve to pre-treat the drinking water and protect the downstream water softener and reverse osmosis system from harmful substances in the water. In doing so, they create the conditions for reliable and long-lasting operation of the subsequent treatment stages. Water softener The water softener reduces water hardness by removing the hardness-causing elements calcium and magnesium from the drinking water and exchanging them for sodium ions. The ion-exchange process thus reduces the load on the downstream reverse osmosis system and protects its membranes from deposits and blockages. Reverse osmosis Reverse osmosis works by reversing the principle of natural osmosis. The softened water is forced under pressure through a semi-permeable membrane. In this process, mainly water molecules and very small molecules pass through the membrane, whilst salts, bacteria, viruses and larger particles are largely retained. The reverse osmosis system used in NeoDeWa achieves a retention rate of around 98 per cent in terms of dissolved substances in the water. Permeate tank A sturdy cylindrical tank is used to store the treated water. Its uniform shape facilitates efficient storage and makes cleaning easier. The optimised tank design is also intended to minimise areas where microbiological contamination is likely to develop. In this way, the tank contributes to the hygienic storage of the treated water. Pressure-boosting station The pressure-boosting station provides the required operating pressure and flow rate for the connected consumers. This ensures that the treated water is available to the connected consumers as and when required, at the necessary pressure levels. Two-stage mixed-bed system Further treatment is carried out by a two-stage mixed-bed system connected in series. The specially matched resins remove any dissolved substances remaining in the water after reverse osmosis. The reduction of silicates is of particular importance here, as these can lead to undesirable deposits during the processing of medical devices. If the optionally available buffer tank system is used, the mixed-bed system also handles the first stage of the recirculation process. Aqua-Stop with solenoid valve shut-off – optional The optional Aqua-Stop serves as an additional safety feature for the water supply. If a fault or leak is detected, it can automatically cut off the water flow. The Aqua-Stop is installed as the first component directly behind the system’s main water connection. Two sensors monitor for potential water leaks: one is located in the cabinet’s base tray, whilst the second is situated outside the cabinet at the level of the permeate tank and pressure-boosting station. An integrated drip tray collects any water that escapes. Together with the Aqua-Stop, it provides an additional layer of safety for the cabinet system. UV system for water disinfection – optional NeoDeWa can be optionally fitted with a UV system for water disinfection. The water is treated with UV-C radiation to reduce the proliferation or contamination caused by microorganisms. Depending on the system configuration, this can inactivate bacteria, viruses and protozoa, amongst others. The UV treatment is carried out without the addition of chemical disinfectants. Pyrogen filter – optional An optional pyrogen filter is used for the targeted removal of pyrogens from the water. These are substances that can trigger immunological reactions in the human body. Relevant pyrogens include, in particular, endotoxins, which can be released, for example, by Gram-negative bacteria such as Escherichia coli (E. coli). Wastewater discharge via a wastewater lifting system – Option For installation sites without adequate free wastewater drainage, NeoDeWa can be optionally fitted with a wastewater lifting system. This collects the wastewater produced and discharges it into the sewerage system. The main volumes of wastewater are generated during the regeneration of the water softener and from the concentrate produced by the reverse osmosis system. NeoTecMaster® 5-inch with housing – optional A modern water treatment system generates a wide range of relevant process data. To record, visualise and process this data, NeoDeWa can be optionally fitted with the NeoTecMaster®. This manufacturer-independent multi-parameter system enables the networking of different measurement systems and their integration into process automation. This allows relevant operational and quality data to be recorded centrally and presented clearly. One system, many possibilities From pre-treatment through softening and reverse osmosis to further treatment and continuous quality monitoring: NeoDeWa combines the individual process steps into a modular complete system. The capacity and configuration are tailored to actual requirements and on-site conditions. Additional components can be added as required – for deionised water treatment that can be flexibly integrated into a variety of outpatient facilities.

Compact and space-saving During the development of the cabinet system, particular emphasis was placed on minimising the space required. Together, the two cabinets require a footprint of just 1.60 m × 1.00 m. With each cabinet measuring 80 cm in width and 60 cm in depth, the system is also suitable for confined spaces. The double-leaf doors open only slightly outwards, thus facilitating access to the components. Robust for day-to-day use The cabinets are made of sturdy sheet steel with a high-quality, durable surface coating – designed for long-term use in everyday outpatient practice. NeoDeWa combines performance tailored to your needs, compact dimensions and a robust design in a seamlessly integrated system. Integrated system separator to protect the drinking water supply A system separator is required to prevent treated water from flowing back into the drinking water supply. NeoDeWa comes with an integrated Type BA system separator as standard. It is located directly behind the optionally available Aqua-Stop at the water connection and ensures a secure separation between the water treatment system and the drinking water supply. Testomat® 808 SiO₂ for monitoring the silicate content The Testomat® 808 SiO₂ continuously monitors the silicate content of the treated water, thereby enabling verification of compliance with the SiO₂ limit of 0.4 mg/l recommended by the DGSV and AKI. Continuous measurement provides transparency regarding this important quality parameter and helps to identify at an early stage any potential adverse effects caused by an elevated silicate content. Continuous conductivity measurement The integrated conductivity measurement at the second mixed-bed unit continuously monitors water quality within a measurement range of 0–10 µS/cm. A conductivity of < 1 µS/cm is recommended for the processing of medical devices. Continuous measurement allows for immediate verification of whether this value is being maintained. Filter systems for reliable pre-treatment The pre-filter section consists of a pre-filter and an activated carbon filter. Both serve to pre-treat the drinking water and protect the downstream water softener and reverse osmosis system from harmful contaminants. In doing so, they lay the foundation for reliable and long-lasting operation of the subsequent treatment stages. Water softener The water softener reduces water hardness by removing the hardness-causing elements calcium and magnesium from the drinking water and replacing them with sodium ions. The ion-exchange process thus reduces the load on the downstream reverse osmosis system and protects its membranes from deposits and blockages. Reverse Osmosis Reverse osmosis reverses the principle of natural osmosis: the softened water is forced under pressure through a semi-permeable membrane. In this process, mainly water molecules and very small molecules pass through the membrane, whilst salts, bacteria, viruses and larger particles are largely retained. The reverse osmosis system used in NeoDeWa achieves a retention rate of around 98 per cent with regard to dissolved substances in the water. Permeate tank A sturdy cylindrical tank is used to store the treated water. Its uniform shape promotes efficient storage and facilitates cleaning. The optimised tank design is also intended to minimise areas where microbiological contamination is likely to form – thereby contributing to hygienic storage. Pressure-boosting station The pressure-boosting station provides the required operating pressure and flow rate for the connected consumers. This ensures that the treated water is available to the connected consumers as and when required, at the necessary pressure levels. Two-stage mixed-bed system Further treatment is carried out by a two-stage mixed-bed system connected in series. The carefully matched resins remove any dissolved substances still present in the water following reverse osmosis. The reduction of silicates is of particular importance here, as these can lead to undesirable deposits during the processing of medical devices. If the optionally available buffer tank system is used, the mixed-bed system also handles the first stage of the recirculation process. Aqua-Stop with solenoid valve shut-off – optional The optional Aqua-Stop acts as an additional safety device for the water supply and can automatically cut off the water flow if a fault or leak is detected. It is installed as the first component directly behind the system’s main water connection. Two sensors monitor for potential water leaks: one in the cabinet’s base tray, and the second outside the cabinet at the level of the permeate tank and pressure-boosting station. An integrated drip tray collects any leaking water and, together with the Aqua-Stop, provides an additional layer of safety for the cabinet system. UV system for water disinfection – optional NeoDeWa can be optionally fitted with a UV system for water disinfection. The water is treated with UV-C radiation to reduce the proliferation or contamination caused by microorganisms. Depending on the configuration, this can inactivate bacteria, viruses and protozoa, amongst others – the UV treatment takes place entirely without the addition of chemical disinfectants. Pyrogen filter – option An optional pyrogen filter is used for the targeted removal of pyrogens from the water – substances that can trigger immunological reactions in the human body. Relevant pyrogens include, in particular, endotoxins, which can be released, for example, by Gram-negative bacteria such as Escherichia coli (E. coli). Wastewater discharge via brine lifting system – Option For installation sites without adequate free wastewater drainage, NeoDeWa can be optionally fitted with a wastewater lifting system that collects the wastewater produced and feeds it into the sewerage system. The main volumes of wastewater are generated during the regeneration of the water softener and from the reverse osmosis concentrate. NeoTecMaster® 5-inch with housing – option Modern water treatment generates a wide range of relevant process data. For the recording, visualisation and processing of this data, NeoDeWa can be optionally fitted with the NeoTecMaster®. This manufacturer-independent multi-parameter system enables the networking of different measurement systems and their integration into process automation, allowing relevant operational and quality data to be recorded centrally and presented clearly.

Additional components can be added as required – for deionised water treatment that can be flexibly integrated into a variety of outpatient facilities.

The benefits of NeoDeWa The NeoDeWa modular water treatment system from HeylNeomeris has been specially developed for the production of deionised water for the reprocessing of sterile medical devices in the outpatient care sector. The major advantage: the system can be individually adapted to on-site conditions. Factors such as the existing water quality, water hardness and water demand are taken into account. Existing treatment stages provided by the water supplier can also be incorporated into the planning. Your benefits at a glance: Individually adaptable to the existing water quality Designed to meet actual water demand Flexible use across different levels of water hardness Modular design enables configuration tailored to requirements Consistently compact design despite customisation This provides you with a water treatment solution that is specifically tailored to the requirements of your outpatient treatment centre. Deionised water treatment for outpatient care Why is deionised water required? Fully deionised water, or deionised water for short, is an important component in the reprocessing of medical instruments and medical devices. It is required, for example, to supply RDGs and Steris in instrument reprocessing or in laboratory applications. The treatment process removes minerals, salts and other undesirable components from the water. This helps to reduce residues and deposits on instruments and equipment and supports a reprocessing method that is gentle on materials and hygienically safe. Deionised water is used, amongst other places, in: outpatient surgical centres dental practices dermatology clinics endoscopy centres other facilities with instrument reprocessing units Reliable monitoring of water quality Consistently high water quality is particularly important for the processing of medical devices. That is why key water parameters can be monitored continuously. These include, in particular, conductivity and silicate content. They provide an indication of the quality of the treated water and help to prevent unwanted residues and deposits. The NeoDeWa Concept The NeoDeWa water treatment system combines the necessary treatment steps into a modular, integrated system. From pre-filtration and softening, through reverse osmosis, to further treatment and monitoring of water quality, the individual components are coordinated with one another. Depending on the facility’s requirements, the system can be individually configured and expanded to include additional components. Components of the NeoDeWa water treatment system Depending on the model, the system includes: A system isolator to protect the drinking water supply Pre-filters and activated carbon filters for pre-treatment of the water A water softener to reduce water hardness Reverse osmosis unit to remove the majority of dissolved substances from the water Permeate tank with a capacity of 100, 200 or 300 litres Pressure-boosting station for a reliable water supply Two-stage mixed-bed system for further water treatment Conductivity measurement to monitor water quality Testomat® 808 SiO₂ for monitoring the silicate content Circulation loop for water circulation when there is no consumption by end-users Optionally, the system can be further equipped with: Aqua-Stop and drip tray UV system Pyrogen filter Brine pumping system NeoTecMaster Your benefit: a fully integrated system With the NeoDeWa VE water treatment system, outpatient facilities receive not just individual components, but a fully integrated water treatment system – all from a single source: HeylNeomeris. The modular design makes it possible to adapt the system to water quality, water demand and the facility’s individual requirements. At the same time, key parameters can be monitored and additional functions integrated as required. This results in a compact and tailor-made solution for the reliable supply of deionised water in the outpatient sector. NeoDeWa Water Treatment System – Flexible capacity for varying requirements The NeoDeWa water treatment system can be adapted to the facility’s specific deionised water requirements. Depending on the model, different capacity options are available: 90 litres per hour 150 litres per hour 230 litres per hour 300 litres per hour The size of the permeate tank can also be selected to suit the required water volume. For larger systems with a capacity of more than 150 litres per hour, the permeate tank and pressure-boosting station are usually installed outside the cabinet system due to their dimensions. The exact configuration depends on the conditions on site. Compact and space-saving The cabinet system has been designed to take up as little space as possible. A floor area of just 1.60 m × 1.00 m is required to accommodate the two cabinets. Each cabinet is 80 cm wide and 60 cm deep. The double doors require very little additional space when opened. This makes the system suitable even for areas where space is limited. Robust and designed for daily use The cabinets are made of sturdy sheet steel and feature a high-quality, durable surface coating. The NeoDeWa cabinet system thus combines flexible performance, compact dimensions and a robust construction in a solution tailored to the specific application. Shut-off via a system separator To protect the drinking water supply, it is essential to prevent treated water from flowing back into the drinking water mains and thereby compromising the quality of the drinking water. A so-called system separator is therefore required. The system is already fitted with an integrated system separator, type BA. This is located directly behind the optionally available Aqua-Stop on the water connection and ensures a secure separation between the drinking water mains and the system. Testomat® 808 SiO₂ silicate analyser A Testomat® 808 SiO₂ silicate analyser is used for continuous silicate monitoring. The Testomat® 808 SiO₂ is a measuring instrument used to determine the silicate content in water. The use of the Testomat® 808 SiO₂ ensures reliable compliance with the limit value of 0.4 mg/l for SiO₂ recommended by the DGSV and AKI. Conductivity measurement The integrated conductivity measurement provides continuous monitoring of conductivity in the range of 0–10 μS/cm at the second mixing bed. For the reprocessing of medical devices, a conductivity of <1 µS/cm is recommended for the water used in the cleaning, disinfection and sterilisation processes. Compliance with this limit is continuously monitored. Filter systems The pre-filter section is a filter unit comprising a pre-filter and an activated carbon filter. Its main purpose is to protect downstream water softeners and reverse osmosis systems, which could be damaged by impurities in the water. Water softener The water softener removes hardness minerals (calcium and magnesium) from the drinking water and replaces them with sodium. It operates on the principle of ion exchange and ensures that the reverse osmosis membranes are reliably protected against blockages. Reverse Osmosis Reverse osmosis reverses the natural osmotic process. In this process, the softened water is forced under pressure through a membrane, which allows only water molecules and very small molecules to pass through whilst retaining larger particles such as salts, bacteria, viruses and other contaminants. The reverse osmosis system installed has a retention rate of approximately 98 per cent, based on all substances dissolved in the water. Permeate tank The built-in cylindrical tank offers advantages in terms of stability, cleaning and space requirements. Its uniform shape ensures that the water is treated and stored efficiently. The optimised tank geometry prevents the potential growth of microbiological contamination and thus goes a long way towards meeting the high standards required for media purity. Pressure-boosting station The pressure-boosting station ensures that the connected consumers are supplied with the required operating pressure and necessary flow rate. This enables an optimised and demand-driven supply of media. Two-stage mixed-bed system The two-stage (series-connected) mixed-bed system acts as a so-called ‘polisher’. Thanks to the special composition of the resin contained in the cartridges, all dissolved substances remaining in the water are reliably removed. The resin used is highly effective against silicates, which have a particularly adverse effect on the processing of medical devices. The mixed-bed unit also serves as the first stage of the recirculation process when the optionally available buffer tank system is used. Aqua-Stop (solenoid valve shut-off) – optional An Aqua-Stop is a safety mechanism used in water supply systems to stop or limit the flow of water in the event of a fault or a leak. The Aqua-Stop is positioned directly as the first component after the system’s main water connection. The associated solenoid valve is linked to two sensors, one of which is integrated into the cabinet’s base tray and the other is located externally at the level of the tank and the pressure-boosting station. The integrated drip tray serves to detect leaks and thus acts as a safety feature; it forms an integral part of the cabinet systems in combination with the Aqua-Stop. UV water disinfection system – optional The development of water disinfection using UV irradiation has made significant progress in recent years due to its simplicity and efficiency. The UV-C rays generated, which are significantly more intense than sunlight, are therefore used to disinfect water in order to combat bacterial contamination. They enable the removal of Legionella, microbes, bacteria, viruses and protozoa, whilst being environmentally friendly. Pyrogen filter – option A pyrogen filter is a specialised type of filter used in water treatment to remove pyrogens from the water. Pyrogens are substances that can trigger an immunological reaction in the body, in particular a rise in body temperature. These are usually endotoxins released by bacteria such as Escherichia coli (E. coli). Wastewater discharge via brine lifting system – option As an optional component, the treatment plant can be expanded to include an integrated wastewater lifting system, which conveys the wastewater produced and collected into the sewerage system. The main wastewater flow streams here are the wastewater from the regeneration of the water softener and the concentrate from the reverse osmosis system. NeoTecMaster® 5-inch with housing – Option Data acquisition, visualisation and processing are just some of the key aspects of modern water treatment. The networking of a wide variety of measurement systems and their integration into process automation is a fundamental component of this. The NeoTecMaster® was developed specifically for this task and is a manufacturer-independent multi-parameter system.
