Abstract (en)
[origin: WO9941204A1] The present invention is directed to an apparatus (10) and method for the treatment of water by generating a purifying gas from anions in the water. Preferably, the apparatus (10) and method of the present invention provide for the purification of water by the generation of chlorine at the anode (20) from naturally occurring chloride in the water. The electrolytic cell (10) of the present invention includes a closed electrolytic chamber (12) having a lower inlet opening (14) and an upper outlet opening (16) for directing water to be treated through the chamber. Disposed within the chamber (12) are an anode (20) and a cathode (30) in electrical contact with a conventional direct current power source. Disposed about the anode (20), preferably substantially surrounding the anode (20) and forming the walls of an anode compartment are a plurality of porous membranes (24) disposed so that water must pass sequentially through each membrane before contacting the anode. In the presently preferred embodiment, these porous membranes (24) comprise alternating layers of polypropylene felt and microporous polytetrafluoroethylene film. Most preferably, the cell (10) includes 2-6 sequentially disposed porous membranes (24).
