ELECTROCHEMICAL GENERATION OF CHLORINE FOR DISINFECTION IN CONTINUOUS FLOW PROCESS

In-situ generation of chlorine was obtained by electrochemical process using Metal Oxides - coated titanium as anode and Titanium as cathode. In this process, its effect will be mainly based on the electrochemical production of hypochlorite and/or hypochlorous acid from the chloride content of th...
