US 2004/0168933 A1 · Method and apparatus for producing electrolyzed water

Abstract

The present invention provides a method and an apparatus for producing electrolyzed water, in which an anion-exchange membrane 2 is provided in an electrolytic cell 1 so as to separate the electrolytic cell 1 to two chambers at the center; each of the chambers separated by the anion-exchange membrane 2 has a discharge port 11a or 11b for the electrolyzed water; an electrode is disposed in each of the chambers of the electrolytic cell 1; a power source is electrically connected to each of the electrodes so as to apply voltage between each of the electrodes; and an electrode selector 5 switches the polarity of each of the electrodes at predetermined time intervals. Thus, it is possible to continuously supply the acidic water maintaining the required concentration of chlorine, improve the efficiency of the treatment and decrease the manpower for cleaning the anion-exchange membrane.
