Abstract
A method and apparatus for the electrochemical treatment of an aqueous solution in an electrolytic cell is described. Output solution having a predetermined level of available free chlorine is produced by applying a substantially constant current across the cell between an anode and a cathode while passing a substantially constant throughput of chloride ions through the cell.

A method of operating an electrochemical cell to produce an output solution having a predetermined level of available free chlorine and pH, wherein the cell comprises an anode chamber and a cathode chamber separated by a separator, wherein the anode chamber includes an anode and the cathode chamber includes a cathode, the method comprising applying a substantially constant current across the cell between the cathode and the anode, passing a substantially constant throughput of chloride ions through the cell, and controlling the pH of the output solution by recirculating at least part of the output solution from the cathode chamber into the anode chamber.
A method of electrochemical treatment of an aqueous salt solution in an electrolytic cell comprising an anode chamber and a cathode chamber separated by a separator, wherein the anode chamber includes an anode and the cathode chamber includes a cathode, and wherein an output solution having a predetermined level of available free chlorine and pH is produced by applying a substantially constant current across the cell between the anode and the cathode while passing a substantially constant throughput of chloride ions through the cell, and wherein the pH of the output solution is controlled by recirculating at least part of the output solution from the cathode chamber into the anode chamber.
