emec LOTUS MINI 8 - Chlorine dioxide generator

The LOTUS MINI system is a device for the production, dosing and monitoring of chlorine dioxide for the disinfection of water and is available as a system with a capacity of 8 g/h (192 g/day) and as a system for up to 20 g/h (480 g/day). Chlorine dioxide is produced by the acid-chlorite process from diluted hydrochloric acid (HCl 9%) and sodium chlorite (NaClO2 7.5%).

Chlorine dioxide production by LOTUS MINI can be controlled according to the flow rate of the water or according to a predefined setpoint.

No chlorine dioxide is stored or saved, so neither chlorine dioxide gas nor concentrated solutions are produced outside the process application.

LOTUS MINI is designed so that chlorine dioxide is generated in a special reaction chamber. Safety is ensured by multifunction valves at the injection points in the reaction chamber. The starting chemicals are stored in tanks and fed into the reaction chamber via suction lances. Integrated fill level sensors stop the pumps automatically when the tanks are empty.

The Lotus Mini system is equipped with the following components:

•        The Lotus control unit
•        Dosing pumps for HCI (red) and NaCIO2 (blue)
•        A pump for dilution water (grey)
•        3SEFL flow sensors to ensure increased safety
•        An MFKT/V multifunction valve that regulates pressure and safety and acts as an antisiphon and drain valve
•        A reaction chamber
•        Injection valves
•        2 suction lances

Advantages:

•        Reaction under atmospheric pressure
•        High stability of the chlorine dioxide solution
•       No loss of CIO2 due to closed reaction chamber

•        Use of diluted chemicals

Functions:

•        Immediate CIO2 production
•        Proportional CIO2 dosing
•        Flow monitoring input (flow alarm)
•        Tank level monitoring (level alarms)
•        Water meter connection
•        Standby input
•        Real-time production data
•        Monitoring of pumps and flow sensors (SEFL)
•        Continuous data storage with system data log (logbook in the menu)
•        ERMES communication
•        mA output
•        Display of the next service date
•        Optional USB data protocol
•        Optional Ethernet module
•        Optional internal GSM/GPRS modem

Characteristics:

•        CIO2 concentration: 2g/l
•        Dosing pumps for HCI (red), NaCIO2 (blue) and dilution water (grey)
•        3 SEFL control sensors for monitoring pump dosing
•        MFKT/V multifunction valve for pressure and safety, as antisiphon and drain valve
•        Reaction chamber made of PVC
•        Housing made of ASA (acrylonitrile-styrene-acrylate copolymer)
•        Protection class IP65 (NEMA4x) for the LOTUS control unit and pumps
•        Rotary control for easy programming
•        Operating temperature: 0/45°C (32/110°F)
