Capital Controls® Chlorine Dioxide Generators

For generations, the Capital Controls® name has been synonymous with disinfection in water treatment. With hundreds of chlorine dioxide generator installations around the world, De Nora has leveraged that expertise, developing the next stage in chlorine dioxide disinfection - a modern, flexible, and safe line of chlorine dioxide generators

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.

De Nora offers a range of systems under vacuum or under water, which ensures the safe operation of the systems.

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® L30 series generators use commercially available 25-31% sodium chlorite and 31% hydrochloric acid  to produce chlorine dioxide for water treatment.  The underwater design employs a submerged reaction chamber and inline configuration, providing maximum yield and safety, without requiring chlorine gas or sodium hypochlorite (bleach).  

The Capital Controls® T70 series generators use commercially available 31% hydrochloric acid and 25-31% sodium chlorite to produce chlorine dioxide for water treatment, without requiring chlorine gas or sodium hypochlorite (bleach). 

New to the family are the ISIA L and U type underwater chlorine dioxide generators. The systems combine hydrochloric acid and sodium chlorite in a reactor that is submerged under water to ensure superior safety, and can be injected directly into a pressurised pipe or water basin.
