A method for cleaning a filtration screen having screen regions gapped from a closest approach of an intake opening of a suction scanner is disclosed. The method comprises providing immovable tunneling means between the screen regions and a location of the closest approach, whereby tunneling a suction power of the suction scanner to respective spots on the screen regions when closely approached, respectively, by the intake opening.

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.
