Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a method for regenerating an electrolytic ozonized water producing unit when the ozone concn. is lowered and to furnish the electrolytic ozonized water producing unit capable of being appropriately regenerated.

SOLUTION: Water is continuously introduced into the electrolytic cell having a high molecular electrolyte membrane 1, an anode 2 and a cathode 3, and a DC voltage is applied between the anode and cathode to produce water from the anode side. When the device is regenerated, an acidic soln. is supplied to the electrolytic cell to clean the membrane 1, anode 2 and cathode 3. Otherwise, deionized water or distilled water is supplied to the anode side, and electrolysis is conducted to regenerate the membrane 1.
