Because it does not form TTHM or HAA disinfection byproducts (DBP), chlorine dioxide is ideal for pre-oxidation of surface water for drinking water applications. Chlorine dioxide oxidizes iron and manganese, is effective over a wide pH range, and does not react with ammonia. It is used for Legionella control, membrane pre-treatment and biofouling control, algae control, and disinfection/oxidation of ammonia-rich waters such as fish farming.
The Capital Controls® G50 series generators use commercially available chlorine gas and 25-31% sodium chlorite to produce chlorine dioxide for water treatment, making it ideal for applications where chlorine gas is used for primary disinfection.
The CAPITAL CONTROLS® G50 chlorine dioxide generator is a two-chemical system, utilizing chlorine gas and 25 – 31 wt % sodium chlorite in the production of chlorine dioxide. The G50 is an all-vacuum system with capacities from 250 lb/day (5 kg/h) to 2500 lb/day (50 kg/h).
