A self-cleaning water filter, coupled to a water flow having particulat es therein, that includes a pair of canisters, each having a cylindrical wedge wire water filter screen. An elongated brush running the length of the screen is dispos ed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with th e elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber. A drain is in fluid communication with the drain subchamber. During cleaning, the drain is opened and the screen is rotated against the brush fo r liberating the particulate contaminants and a limited amount of the water flow into the two dislodge subchambers. The particulate contaminants and the limited amount of water th en pass through the apertures at a high velocity and into the drain subchamber which exits through the drain. Alternatively, a reverse flow of clean water can be used in combination with the elongated brush, for dislodging the particulate contaminants from the water filter. Finally, another variation of using a reverse flow of wate r for cleaning purposes is discussed whereby a stationary water filter is disposed in a system that isolates the water filter from the normal water flow during cleaning.</SDOAB >
