The CAPITAL CONTROLS® L30  chlorine dioxide generator is a two-chemical system, utilizing 31 wt % hydrochloric acid and 25- 31 wt % sodium chlorite in the production of chlorine dioxide. A proven design, durable construction and the use of  the best available corrosion-resistant materials assure efficient chlorine dioxide production, precise solution feeding, low maintenance and dependable operation for the life of the equipment.

Key Benefits:

Inline Submerged Reactor: The reagents are drawn into the inline reactor by the chemical dosing pumps. The chlorine dioxide solution concentration is less than 1 g/L %.

Capacities: Standard chlorine dioxide generator units are available in a range of capacities from 250 lb/day to 1500 lb/day (5 kg/h to 30 kg/h) of chlorine dioxide.

Description of Operation

The acid and sodium chlorite reagents are pumped into the inline submerged reactor. Reagent flow is controlled by dosing pumps with 1:800 turndown ratio which are individually sized for each dosage capacity.

The chlorine dioxide solution is pumped out of the inline submerged reactor by the effect of the pressure produced by the dilution water pump. The solution   is passed through a sight glass for visual verification of product quality. The entire reaction zone is completely submerged.

An automatically controlled system utilizes input signals for flow, residual or flow + residual control.
