Zusammenfassung:In a process for producing sodium hypochlorite in an electrolytic cell comprises forming an aqueous based chloride solution with a chloride salt; controlling the concentration of chloride within the solution to an amount comprising less than 25 g/L chloride salt; piping the salt solution to the electrolytic cell, the electrolytic cell comprising an anode and a cathode, the cathode comprising a metallic base material, a first coating on the metallic base material and a second non-conductive ceramic coating on the metallic base material. The chloride solution is then in contact with the anodes and cathodes and an electric current is sent throughout the electrolytic cell to produce hypochlorite. During this process the electric current is controlled so that the power consumption is less than 2.5 kWh per pound of hypochlorite produced and the resulting cell efficiency comprises less than 2.5 kg of chloride salt consumed for every 1 kg of hypochlorite generated.
