Apparatus for the treatment of water
First Claim
1. In an apparatus for destroying algae in pool water:
- a flowpath for pool water;
a plurality of plates made of titanium metal and disposed in said flowpath and spaced such that pool water flows between said plates in pairs;
means for connecting said pairs of said plates to a source of electrical potential such that one plate of each pair is made electrically positive with respect to the other plate of each pair;
means for reversing the relative polarity of the plates of a pair;
a quantity of copper and a quantity of silver joined together to form an electrochemical junction and both disposed in said flowpath such that pool water is made to contact both the copper and the silver; and
means for preventing flow of pool water over said junction.

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.

-
a flowpath for pool water; a plurality of plates made of titanium metal and disposed in said flowpath and spaced such that pool water flows between said plates in pairs; means for connecting said pairs of said plates to a source of electrical potential such that one plate of each pair is made electrically positive with respect to the other plate of each pair; means for reversing the relative polarity of the plates of a pair; a quantity of copper and a quantity of silver joined together to form an electrochemical junction and both disposed in said flowpath such that pool water is made to contact both the copper and the silver; means for preventing flow of pool water over said junction; the quantity of copper and of silver being disposed in an electric field such that there is a potential gradient between them; and said flowpath being formed by a housing comprising a body portion the interior wall of which defines a cavity and an inlet element and an outlet element through which communication may be had to said cavity; the interior walls of said body portion being formed with conformations arranged to hold adjacent ones of said plates in fixed spaced relation to one another and to hold said interconnected quantities of copper and silver in fixed spaced relation to said plates. - View Dependent Claims (4, 5, 6, 7)
