Patent ID: 7037427

Claim:
A filter device for the clarification of contaminated liquids, comprising: a plurality of disk-shaped filter elements spaced apart from one another and combined into circular or polygonal filter modules and arranged rotatably about a horizontal axis in a vessel containing the unclarified liquid, the filtrate being capable of being discharged via the individual filter modules; the filter modules forming centrally a cavity, the cavity on one side being closed by a carrying disk and on the other side being connected to the vessel via a suction-intake orifice, and the cavity being connected operatively to a flow member in such a way that, via the suction-intake orifice, a flow can be generated in the unclarified liquid between the spaced-apart filter elements and avoids an adhesion of solids to the filter elements; and wherein said carrying disk is in the form of a flat plate that extends completely across said one side of the cavity.
