Abstract
An electrolytic cell combined into a unitary structure with a liquid circulation fitting, which purifies water by electrode plates inside the cell when an aqueous solution is present. The unitary structure replaces the existing water return fitting. This integrated structure is well suited for use in pools, tubs, spas, fountains or similar large liquid containers. The production of halogen inside the structure is not required to coincide with the cycle of the existing pool filtration system. Rather, the electrodes receive a continuous supply of low level power and the halogen produced inside the structure is disbursed back into the body of water through the fitting using an integrated, dedicated circulation pump, special channels in the surface and a check valve to insure one directional flow from the pool pump and natural convection. Using fresh water drawn from the vessel, halogen is then disbursed back into the vessel with the water at a location different from where the fresh water was drawn. The level of halogen production may be regulated using a timing mechanism and/or sensors in the circuitry.
