Abstract: Water purification is accomplished in a swimming pool, spa or decorative pool body of water by adding salt in quantities sufficient to make the water slightly conductive and by circulating that water through the electric field between a pair of electrode plates where the dissociated ions of salt and water are converted to oxidizing agents capable of destroying organic matter and are converted to substances that can be removed in such a mechanical filtration system. That process results in economical and effective purification which is augmented in one form of the invention by the inclusion in the water circulation path of dissimilar metals which aid in the destruction of organic matter. The process is facilitated by the use of a special electrochemical processing unit in which the electrode dissociation is accomplished.
