Chlorine dioxide is an extremely effective water disinfectant against all types of pathogens, it also destroys biofilms, thus eliminating the food source of microorganisms and thus preventing their formation. Furthermore, its disinfectant capacity is independent of the pH level of the water.

It is used in water purification and purification processes, in the disinfection of water in sanitary systems and water for industrial, food and process use. The main disadvantage of chlorine dioxide is its instability; it is in fact a very reactive gas, which must be produced on site.

The CDG generator has been designed to produce chlorine dioxide in aqueous solution and store it in a storage tank, for subsequent regulated dosing. A PLC equipped with a touch-screen display manages the entire system; allows simple and intuitive interaction of all system configuration, start-up and blocking operations, choice of operating mode and error management.

Furthermore, the system includes various safety controls, such as level sensors, flow controls and chlorine dioxide gas sensor in air.
