A method and apparatus for generating electrolyzed water is described. An electrolyte aqueous solution is circuited through a first electrolysis chamber 3a, of two electrolysis chambers placed on opposite sides of an ion-permeable membrane 2. Raw water is supplied only to the second electrolysis chamber 3b. A voltage is applied between electrodes 7a and 7b. Electrolyzed water generated in the second electrolysis chamber 3b is drawn out. The concentration of the electrolyte aqueous solution circulated through the first electrolysis chamber 3a is maintained within a predetermined range. The membrane 2 is an anion-exchange membrane. The electrolyte aqueous solution is circulated through the first cathode-side electrolysis chamber 3a; raw water is supplied only to the second anode-side electrolysis chamber 3b; and acid electrolysed water generated in the anode-side electrolysis chamber 3a is drawn out. The electrolyte aqueous solution is NaCI or KCI aqueous solution. The concentration is maintained within the predetermined range by adding hydrochloric acid according to the pH of the NaCI or KCI solution or the amount of reaction of this solution computed from the amount of energization during the electrolysis. |
