ABSTRACT:
A backwash strainer is equipped with a mechanism for enhancing performance of a backwash operation by imparting a cyclonic flow to liquid to be filtered. The backwash strainer includes a generally cylindrical filter element that defines an interior chamber having an inlet through which liquid to be filtered can flow. A backwash arm is rotatably mounted within the interior chamber of the filter element. An impeller ring is positioned proximal the inlet for imparting cyclonic flow to a liquid flowing therethrough.
