 CHLORIDIOX CP SERIES - Onsite Chlorine Dioxide Generators
The IEC chlorine dioxide generator offers a simple and effective way of generating a low strength chlorine dioxide solution.
- Safe, on-demand production of chlorine dioxide
- Simple, reliable operation. Safety interlock as mandatory
- Fully automatic or manual operation
- Low maintenance
- metering pumps for precise metering
- Calibration columns provide a simple, economical method for settling pump flow rates
- As basic chemicals for the generation of chlorine dioxide unit uses hydrochloric acid (32% Hcl) and sodium chlorite (25% NaClO2). Both reagents are metered directly from commercial carboys or intermediate storage tanks into the reaction tower where a chlorine dioxide solution is produced.
The CHLORIDIOX Advantage
- Operates simply, reliably and safely
- Retrofits easily into existing chlorination facilities
- Minimizes materials handling and maintenance
- Eliminates chlorine gas & concentrated hypochlorite solutions
- Produces stable, low concentration chlorine dioxide
- Modular construction for adding generators adjacent
The Process
Acid-chlorine is the simplest and easiest to operate generation chemistry. This is a consequence of the use of only two feeds and its simple reaction chemistry. Instead of having to balance the amounts of sodium chlorite and hydrochloric acid, one merely has to provide sufficient hydrochloric acid. The theoretical conversion of sodium chlorite to chlorine dioxide is only 80%.

CHLORINE DIOXIDE
Chlorine dioxide is a reactive oxidizing gas that is readily soluble in water. Even dilute solutions (10 ppm) of chlorine dioxide have a characteristic yellow color. The maximum chlorine dioxide concentration typically 4000 ppm. This is to minimize the concentration of chlorine dioxide gas in equilibrium with the solution.
GENERATOR AUTOMATION
Chlorine dioxide generators are automated to provide modulation of chlorine dioxide feed rates based upon changes in flow (flow paced control) and chlorine dioxide demand of the water being treated ( residual control). Theoretically, the chlorine dioxide feed rate may be varied by either modulating the precursor chemical feed rates to the generator or by turning the generator on and off.
