Patent ID: 7332081

Claim:
A filter device for clarification of contaminated liquids, comprising: a vessel configured to contain the liquid to be clarified; a first carrying disk arranged within said vessel, said first carrying disk rotationally driven about a rotational axis; mounting rods attached to and extending generally perpendicular from said carrying disk; a plurality of filter modules including spaced apart filter elements extending generally parallel to said carrying disk, each of said filter modules rotationally fixed relative to said carrying disk at least in part by said mounting rods, said filter modules having a radially inward end spaced radially from said rotational axis of said carrying disk; said ends of said filter modules circumscribing a cavity within said vessel having a longitudinal axis corresponding to said rotational axis of said carrying disk; a flow member disposed within said cavity; wherein said flow member is radially spaced apart from the radially inward ends of said filter modules; and wherein said cavity is configured such that a cleaning fluid medium from within said cavity flows radially out from said cavity and between said filter elements to clean said filter elements, said flow member generating the flow of said fluid cleaning medium with said cavity.
