Electro Chlorination: It is a chemical process which uses water, common salt and electricity to produce Sodium Hypochlorite (NaOCl). The brine solution (or sea water) is made to flow through an electrolyser cell, where direct current is passed which leads to Electrolysis. This produces Sodium Hypochlorite instantaneously which is a strong disinfectant. This is then dosed in water in the required concentration to disinfect water, or to prevent Algae Formation and Bio Fouling. The main advantage of electro chlorination is that dangerous chlorine gas can be avoided where brine or sea water is abundantly available.
