ABSTRACT:
A filter assembly includes a housing divided into a first chamber and a second chamber. A filter element is disposed in the first chamber, and a conduit is disposed in and opens to the second chamber. A weep hole introduces a backwash liquid from the second chamber into the filter element or the conduit. A differential pressure is then established between the opening in the conduit and the exterior of the filter element to force the backwash liquid through the filter element and thereby clean the filter element and/or strip a precoat layer from the filter element.
