Patent ID: 8419925

Claim:
In an industrial water processing chamber for water contained therein, wherein the chamber comprises the cathode in a cathode-anode electrolytic system, wherein the processing includes placing a DC voltage between the cathode and the anode, wherein the anode and cathode each includes one contact (juncture) thereon for connecting to either a positive or negative output of a source of the DC voltage, and wherein undesired buildup is formed on the cathode due to the electrolytic processing, a method for cathode renewal by removing all or part of the undesired buildup on the cathode, comprising the steps of: a) attaching a second contact (juncture) to the cathode, wherein the second contact is so placed as to be located a distance away from the first contact; b) placing an electric voltage between the first and second contacts on the cathode so as to cause an electric current to flow across the cathode; c) continuing the application of the electric voltage between the first and second contacts on the cathode for so long a time period, as to cause a desired portion of the undesired buildup to detach off the cathode.
