Abstract: A filter apparatus having means for maintaining a filter element in a state of at least substantially continuous agitation. There is provided a tank having a hollow filter element positioned therein. The liquid being filtered is introduced into the tank exteriorly of the filter element, passes through the filter element in a radially inward direction and the filtered liquid then is withdrawn from the interior of the filter element. At least a portion of the filter element is movably related to the tank and a vibrator unit is provided on the filter element. Operation of the vibrator unit causes agitation of the filter element within the tank and thereby maintains the filter element in a state of constant agitation. It is often convenient to drive the agitating unit by compressed air and if so a pair of hoses will be connected to the agitator unit. Preferably, such hoses will be brought through the ring by which the filter element is supported and then along the length of the filter element to the agitator unit, whereby the filteragitator-hose assembly may be made in a single, easily replaceable unit.

Abstract: A filter assembly having a plurality of individual filter units, each including an impervious outer skirt surrounding an elongated filter member. A fluid-solid mixture is supplied to the filter units in a direction to flow radially inwardly through the filter member. Rotatable backwash arms are disposed adjacent the opposite ends of the filter units for sequentially and progressively permitting backwashing thereof. Tne backwash fluid flows radially outwardly through the filter members for removing the collected solid material. The backwash arms are connected to inlet and outlet pipes, with the inlet pipe being connected to an external source of separate backwash fluid. The backwash arms are rotatably driven by means of external drive system which includes disconnectible means for enabling one end of the filter housing to swingable move into an open position, carrying with it the backwash arm connected thereto, for permitting servicing of the individual filter units.

Abstract: A pressure filtering method and apparatus in which the residual process liquid present in the pressure filter housing at the end of a filtration cycle is discharged from the housing, prior to the backwash cycle, and is sent to a recovery system and is treated so that it can be returned to the main stream of the process liquid.
