For generations, the Capital Controls® name has been synonymous with expert chlorine gas handling. The Capital Controls® all-liquid chlorine dioxide generators produce and consistently maintain a product yield greater than 90%, making it ideal for drinking water treatment. The two-chemical system is designed for use with commercially available 32% hydrochloric acid and 25-31% sodium chlorite without the use of chlorine gas or sodium hypochlorite (bleach).
Acid-Chlorite T70 Series
The Capital Controls® T70G4000 series generators use commercially available hydrochloric acid and 25-31% sodium chlorite to produce chlorine dioxide for water treatment, without requiring chlorine or sodium hypochlorite (bleach).
- 40 years of chlorine dioxide experience
- Inherently safe all-vacuum system
- Up to 529 lb/day (10 kg/hr) on a single skid
- Uses commercially available precursors (does not require chlorine or bleach)
- Does not form TTHMs, effective over a wide pH range, oxidizes iron and manganese
- The all-vacuum system prevents escape of chlorine dioxide gas to the atmosphere and provides fail-safe shut-down with loss of vacuum.
The Capital Controls® all-liquid chlorine dioxide generators produce up to 529 lbs/day (10 kg/hr) of chlorine dioxide from a single generator and higher capacities are available with multiple systems.
Built with corrosion-resistant materials, maintenance is minimal and all periodic maintenance items are easily replaceable. Systems are available with manual or automatic controls.
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.
