ABSTRACT:
A backwash strainer having a generally cylindrical filter element made up of a stack of spaced rings that are triangular in cross section, with the bases of said triangular rings disposed in a cylindrical surface. A hollow backwash arm has an open slot disposed on the inside of the cylindrical surface which operates at a predetermined distance from said element. The incoming water in said strainer flows from the inlet up through the straining element to the outlet. The backwash arm receives water from around the straining element, which flows through the element into the backwash slot and out with the debris accumulated on said strainer. Since the debris is supported on the flat interior of the rings, water flowing back into the arm into the slot in the hollow backwash arm forces trash and other debris from the rings down to the backwash water outlet. Water flowing through the clearance between the bars as used, helps flush the debris off the inside of the filter element.
