    Patent number: 5945005
    Abstract: A filter system (110) includes a tank (130) with a conveyer (140) for, preferably continuously, conveying filter media (11) from a filter zone (119) in the tank (130) where the filter media (11) traps predetermined matter (16), such as particulates, to a quiet zone (115) in the tank (130) where the predetermined matter (16) separates from the filter media (11) and is allowed to accumulate and be withdrawn from the tank (130). The conveyer (140) preferably includes a screw auger (141) and a duct (142) for containing the screw auger (141).
