Do you need sodium hypochlorite that is high-purity or low-chloride and low-chlorate? The electrolysis system CHLORINSITU® III is the solution. The system can be used for potable-, waste-, process-, swimming pool water and in cooling towers.

The CHLORINSITU® III is a membrane cell electrolysis system in which the electrochemical reaction takes place in two electrode chambers (anode and cathode) which are separated by a cation selective membrane. The formation of active chlorine and sodium hydroxide is physically separated.  

Mixture of pure products

In the CHLORINSITU® III the freshly produced sodium hypochlorite (NaOCl) is a mixtures of both pure product (active chlorine and sodium hydroxide) which are mixed in a special reactor forming a solution of sodium hypochlorite (20 – 25 g/l FAC). It can be stored temporarily and metered as needed.

The CHLORINSITU® III systems therefore only need to be designed for average chlorine demand, as peaks of capacity can be compensated for from the sodium hypochlorite (day)storage tank.

The advantage of membrane cell electrolyser systems lies in their excellent efficiency (85% yield) and minimal entrainment of chloride compared with open cell systems. The electrical and chemical yield is very high. Chemical conversion is approx. 85% of brine, resulting in a  low salt- and energy consumption and relatively high chlorine concentrations (20 – 25 g/l FAC) in the end product. The relatively low chloride and chlorate levels into the water to be treated are a result of the CHLORINSITU® III membrane cell technology.
