The LOTUS system produces, doses and controls Chlorine dioxide for water disinfection. Chlorine dioxide is produced from diluted base chemicals: acid-chlorite process by hydrochloric acid (HCl 9%) and sodium chlorite (NaClO2 7.5%).

Chlorine dioxide produced by LOTUS is set to be proprtional to the circulating water flow or based on a set-point – it is then dosed into the water flow. There is no storage of chlorine dioxide hence no chlorine dioxide gas or concentrated solutions exist outside of the process application.

LOTUS is designed so that the reaction to produce chlorine dioxide takes place in a reaction chamber. Multi-function valves on the injection points ensure the security of the reaction chamber.

The base chemicals are stored in tanks and fed into the reaction chamber through suction lances. Integrated level switches automatically stop the pumps when the tanksare empty.
