Patent ID: 8062500

Claim:
A method of producing negative and positive oxidative reductive potential (ORP) water, comprising the steps of: (a) providing a three-chambered electrolysis unit having an anode chamber, a cathode chamber, and a saline solution chamber interposed between said anode and cathode chambers, wherein the anode chamber is separated from the saline solution chamber by a metal anode electrode and a first ion exchange membrane, wherein the cathode chamber is separated from the saline solution chamber by a metal cathode electrode and a second ion exchange membrane, and wherein the saline solution chamber includes a particulate insulating material; (b) providing a flow of water to and through the anode and cathode chambers from at least one water supply in fluid communication with the anode and cathode chambers; (c) providing a circulating fluid flow of saline solution to and through the saline solution chamber from at least one fluid supply, wherein the flow of saline solution through the saline solution chamber is at least about 10 L/min; (d) simultaneously with steps (b) and (c), providing electrical current to the anode and cathode electrodes from a source of electrical potential connected to the anode electrode and the cathode electrode; and collecting ORP water produced by the electrolytic reaction in the electrolysis unit, wherein the negative ORP water from the cathode chamber has a pH of between 6 and 8.
