Abstract
A backwash header for a cloth filter disk includes a body having a length a diameter, first and second ends, a longitudinal axis, and an exterior surface, the body defining at least one internal cavity. The body includes at least one suction slot configured to allow fluids and solids to enter the internal cavity from outside of the exterior surface. A structure is attached to a portion of the exterior surface of the body around and extending away from the suction slot to form a chamber defined by the structure and a portion of the exterior surface near the suction slot. The structure is configured to allow fluids and solids to enter the chamber and then the suction slot and cavity from a material being cleaned. Cloth disk filters and methods of treating water and wastewater using the backwash headers and cloth disk filters.
