ABSTRACT:
A water filter includes a cartridge filter element mounted on a coaxial bearing so it can be spun. During normal operation, a pressure tank enclosure allows the outside of the cartridge filter element to be submerged. Filtered water is then collected by a filtered-water return inside the cartridge filter element. An air vent disposed in the pressure tank housing allows water to drain away before starting a cleaning cycle, and to bleed off trapped air before returning to normal operation. During cleaning, a flow of clean water is applied to the filtered-water drain. A wash drain in the bottom of the pressure tank enclosure allows used cleaning water to flow out. The reverse water flow through the filtered-water drain forces closed a flapper valve. This, in turn, causes a water spray jet manifold to fill under pressure and cleaning water sprays out from slightly offset nozzles directed at the cartridge filter element. The coaxial bearing allows the cartridge filter element to spin under hydraulic pressure from the nozzle jet spray. A combination of cleaning water spray and centrifugal force thus cleans filter cake and debris from the cartridge filter element in situ.
