Abstract
An improved device and method for the creation of acidic electrolyzed water is described. The device has an flow-through anode chamber and a static cathode chamber. The static cathode chamber contains a fixed amount of salt-containing electrolyte, which is renewed as needed. The flow rate of water through the anode is restricted to a range of about 5 to 40 ml per ampere of current passed through the electrode. Electrolyzed water flowing from the anode is diluted to obtain the desired concentration of hypochlorous acid, and is collected in a tank or other vessel. The electrolysis reaction is terminated when a preset amount of current has passed through the anode. Water circulation may be one pass or recycling. In a preferred embodiment, the membrane is anion-selective. Preferably, the membrane and the electrodes are integrated into a preassembled format that can be attached to the anode and cathode compartments via flanges or similar devices allowing quick replacement of an electrode assembly in an electrolyzer. The anion-permeable membrane can be protected by a protection membrane, in which are provided slits or other discontinuities to allow venting of gas.
