A water purification system for use with a pool or the like in which a small quantity of water can be continually withdrawn from the pool for recycling. The system involves the use of silver impregnated activated charcoal granules as a combination filter and antimicrobial agent such that the need for chlorine and other conventional chemical treatment of the pool is eliminated or vastly diminished. A small portion of the water being recycled is diverted and so treated with the silver impregnated activated charcoal such that small amounts of silver ions are released into the water such that the silver concentration in the pool is maintained at a level effective to kill essentially all bacteria present therein.

A water purification system for effectively eliminating bacteria in the water of a swimming pool including a water recycling system including a pump wherein a quantity of water from said pool is continually withdrawn and returned thereto via suitable water conduits, comprising a canister having a hollow body including water inlet and outlet means provided thereon, said body in part forming first and second separate water channels therein, said first channel permitting water to move in an essentially unrestricted flow from said inlet to said outlet, said second channel having silver ion treated granules provided therein whereby water passing through said second channel is filtered by said granules and treated by said silver ions, said body being an elongated tube, a hollow elongated double-walled shell having upper and lower ends in a central interior opening adapted for disposition in said tube with the outer shell wall spaced from the tube inner surface, means defining said central interior opening in said shell forming said first channel and means defining an area between said shell walls forming said second channel, and means defining the space between the outer shell and said tube forming a mixing chamber for admixing said filtered and treated water passing through said second channel with the untreated water passing through said first channel prior to exiting said canister via said outlet means, said inlet means adapted to direct incoming water into the lower end of said shell such that said water enters and its flow proportioned into both of said channels, means connecting both said channels with said mixing chamber at the upper end of said shell, said connecting means including means defining first openings whereby said untreated water passes into said mixing chamber and means defining separate second openings whereby said treated water passes into said mixing chamber, said first openings disposed above said second openings and said outlet means connected to said mixing chamber below both said first and second openings.
