ABSTRACT:
A liquid filter apparatus wherein an elongated sheet of filter media is movable along an inclined support at the bottom of a receiving tank for dirty liquid below which is a collection tank for filtered liquid. The periphery of the collection tank is sealed by clean liquid supplied from an auxillary reservoir at a pressure greater than the liquid in the receiving tank. A suction pump attached to the outlet from the collection tank helps to maintain flow of clean liquid through the media while filtered out material is accumulated on its upper surface. Fresh filter media is pulled into position from a supply roll to replace loaded filter media by drive means controlled to operate automatically after the pressure in the collection tank is substantially equalized temporarily with that in the receiving tank.
