Method and apparatus for controlling water system fouling

This invention relates generally to methods and devices used with water systems. More particularly, it relates to an improved method and apparatus for exposing water, flowing through a water system, to an ion generator whereby ions are fed into the water flow to prevent fouling of the water system by algae, nuisance invertebrates, microorganisms, and inorganic salts. This invention also specifically relates to an improvement of the inventors' method and apparatus disclosed and claimed in U.S. Pat. No. 6,350,385. A method and apparatus for turbulently exposing water flowing through a water system to a plurality of electrodes of an ion generator and having a self-contained tank through which water flows is provided with an inlet pipe that directs water flow between the electrodes. A tank cover serves as a non-electrical conducting head for the plurality of electrodes that extend downwardly from the underside of the cover. The electrodes are functionally configured to maximize water flow between them. Following the flow of water between the electrodes, a double vortex of water flow is created along one wall of the tank. A sight glass allows for visualization of the container contents, and in particular electrode wastage or wear, during operation.
