Abstract
A continuous, self-cleaning, rotary filtering apparatus is provided having a plurality of filter elements within a rotatable filter housing adapted for rotation between an inlet plate having an inlet manifold and an outlet plate having an outlet manifold so that the liquid to be filtered is passed from the inlet manifold through the filter elements and into the outlet manifold. The apparatus is further provided with a backflushing capability whereby the filter housing can be rotated to position where one filter element in alignment with a backflush port independent of the inlet manifold so that a part of the liquid within the outlet manifold will be caused to flow backward through that filter element and backflush port to purge contaminants from the apparatus via the backflush port without interrupting liquid flow through the other filter elements. After backflushing, the filter housing is further rotated to return the backflushed filter element to service.
