  • Method for producing electrolyzed water
    Patent number: 5762779
    Abstract: The method for producing electrolyzed water includes the step of applying a voltage to electrodes disposed in an electrolytic cell containing therein pure water including electrolyte therein. A strength of an electric field generated by applying a voltage to the electrodes is controlled to be variable by means of various techniques. The method makes it possible to produce electrolyzed water with a smaller amount of energy than prior methods.
    Type: Grant

  • Wet processing apparatus having individual reactivating feedback paths for anode and cathode water
    Patent number: 5549798
    Abstract: In a wet processing apparatus, an electrolytic cell, a first storing cell for storing anode active water of the electrolytic cell, a first processing cell for processing a target with the anode active water of the first storing cell, a second storing cell for storing cathode active water of the electrolytic cell, and a second processing cell for processing a target with the cathode active water of the second storing cell are provided. Also, a first reactivating feedback path is provided between the first processing cell and an anode region of the electrolytic cell, and a second reactivating feedback path is provided between the second processing cell and a cathode region of the electrolytic cell.
