ABSTRACT:
An apparatus for cleansing water including a fluid driven cleaner is disclosed herein. The apparatus includes a hollow casing having an upper open end and a central axis, a perforated tube disposed along said central axis inside the casing, the tube being in flow communication with a drinking water control valve, a porous ceramic core filter element disposed around the tube, a cover for covering said upper open end, the cover including an axle, an upper float disposed above the filter element, the upper float including a hole, the axle being rotatably disposed in the hole in the upper float, a lower float disposed below the filter element, the upper and lower floats including fastening means for maintaining a fixed distance between said floats, and a plurality of roller brushes rotatably fasted between the upper and lower floats for cleaning dirt from the outer surface of the filter element, blade means for rotatably driving the floats disposed in the upper and said lower floats, and inlet means for directing a pressurized flow of water to rotatably drive the blade means, whereby pressurized water impinging the blade means causes rotation of the floats such that the roller brushes scrape filtered dirt from the outside surface of the filter element, resulting in automatic cleansing of the filter element.
