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