Claim:
1. A rotary disc filter device comprising: a support structure comprising a housing, and a rotor rotatable about an axis of rotation and rotatably supported by the support structure, the support structure having an inflow port arranged at one end side of the housing in a vicinity of the axis of rotation, the inflow port being connected to an inflow pipe extending through a central portion of the housing and having openings arranged opposite to an interior of a disc-shaped filter member, the rotor comprising a plurality of disc-shaped filter members, each of which having a central breakthrough, wherein the central breakthroughs are in alignment forming a central channel circumventing the inflow pipe and a discharge duct, each disc-shaped filter member having two walls extending outwardly form the axis of rotation, each wall being formed of a frame defining several openings therein, each opening being covered by a filter element, wherein the frame is formed at an inner circumference by a ring-shaped mounting plate extending in a radial direction with respect to the axis of rotation, wherein the disc-shaped filter member has a form of a bifrustum, wherein the disc-shaped filter members are arranged to directly connect to each other with the ring-shaped mounting plate, wherein each wall arranged at an axial end of the rotor is connected with a pipe section arranged coaxially with respect to the axis of rotation, and wherein flush tubes extend from a cover of the housing.
