Patent ID: 8425756

Claim:
A method for producing electrolyzed water, the method comprising the steps of: (a) pumping a conductivity enhancing solution into a supply of feed water to create a feed water solution, and flowing the feed water solution into an input portion of an electrochemical cell, the electrochemical cell comprising an anode chamber and a cathode chamber, the anode chamber comprising an anode electrode and the cathode chamber comprising a cathode electrode, anode chamber and cathode chamber being separated by a membrane; (b) applying a cell current from a power source to the electrochemical cell; (c) sensing the cell current; (d) electrolyzing the feed water solution in the electrochemical cell to produce a separate stream of anolyte solution electrolyzed water in the anode chamber and a separate stream of catholyte solution electrolyzed water in the cathode chamber; (e) comparing the cell current to a predetermined optimum current setpoint; and (f) adjusting the rate at which the conductivity enhancing solution is pumped into the feed water in response to the difference between the cell current and the predetermined optimum current setpoint to maintain the cell current substantially equal to the predetermined optimum current setpoint.
