ABSTRACT:
A moving bed filter in which the liquid to be filtered is introduced into an internal chamber centrally disposed in the filter bed. The liquid flows through the filter bed to filtration nozzles which are disposed near the outer periphery of the filter bed. A portion of the filter bed media is continuously removed from a recessed chamber below the floor of the filter bed, transported by gas lift through a lift conduit to a washbox located above the filter bed, and cleaned by a countercurrent flow of the filtrate.
