ABSTRACT:
A backwashable filter comprises (a) an outer case, (b) a rotatable, permeable filter drum, (c) a fibrous filter element supported on the surface of the drum, (d) one or more stationary backwash arms, (e) a feed inlet leading to one side of the filter drum and (f) a filter outlet emerging from the other side of the drum. The backwash arms are in close contact with the filter element. The tendency of the feedstock to bypass the filter and enter the backwash arms is thereby reduced.
