Abstract: A control mechanism for self-cleaning filtration systems. One embodiment is a controller for a filtration system that comprises a suction scanner and a screening element having modifiable respective locations therebetween. The controller comprises an input terminal for receiving a relative location signal and additional a differential pressure input terminal. The controller monitors differential pressure and outputs an activation signal after the differential pressure has exceeded a threshold value. The controller outputs a termination signal based on the relative location signal. Another embodiment is a filtration system that comprises: a screening element located within a filtration chamber, and a suction scanner for self-cleaning thereof. A location tracker communicates to a switching mechanism during self-cleaning sessions a signal indicative of a location of the suction scanner with respect to the screening element. The switching mechanism automatically terminates self-cleaning sessions based on the signal.

Abstract: A filtration system is disclosed, which comprises a filtration-element within a filtration chamber, and a valving device located exteriorly to the filtration chamber, for reversing the direction of fluid-flow through the filtration-element for backwashing. The valving device thus functions as a common valve for handling both filtration and backwash. The common valve is based on a linearly-movable plug located inside a valve housing which is communicable with the filtration chamber, with a source of fluid to be filtered, and with evacuation port for backwash fluid, through three respective openings in the valve housing, and is characterized by an uninterrupted bend-free flow-channel extending at least from exteriorly to an inlet opening of the valve housing, to the body of the filtration-element whenever the common valve is in a filtration mode of operation.

Abstract: The presently disclosed subject matter is directed to a filtration system. The filtration system comprising a housing and at least one filter assembly extending within the housing. Each of the at least one filter assembly comprising a filter element disposed within the main filtering chamber; a cleaning assembly comprising a suction shaft. The suction shaft comprising at least one suction nozzle along a portion thereof, and being sealed at its one end and configured with at least one exhaust opening at its other end configured for extending within an exhaust chamber. Further comprising a liquid resistant driving mechanism disposed within the exhaust chamber and configured to impart the suction shaft with rotary motion and reciprocal linear motion. The suction shaft is adapted for selectively closing and opening the fluid drain port.
