Method for producing electrolyzed water

Abstract

A method for producing of electrolyzed water comprising, using an electrolyzing apparatus of water having a structural feature to divide an electrolyzer to an anode chamber (D) and a cathode chamber (E) by a diaphragm ( 1 ) and arranging an anode plate ( 3 ) in the anode chamber and a cathode plate ( 4 ) in the cathode chamber and to carry out the electrolysis by filling the water to which electrolyte is previously added, wherein the flow rate of water to be provided to the cathode chamber is restricted to 40 mL/min. per 1A (ampere) of loading electric current or less, and softening previously the water provided to the cathode chamber ( 10 ) alone. It is possible to divide the electrolyzer to three chambers by 2 diaphragms, filling up aqueous solution of electrolysis in the center chamber and to provide the electrolysis by electrophoresis.
