Abstract: A filter member for horizontal disc filters has a base plate having a peripheral edge and a hub connected to the base plate. The base plate has cavities extending in a radial direction of the base plate at a slant toward the hub, wherein the cavities are positioned closely adjacent to one another. The base plate has narrow projections formed between the cavities. A filter medium, providing a support for deposition filtration and cake-forming filtration, is formed as a thin filter plate with very small openings. The hub, the projections between the cavities, and the peripheral edge have support surfaces for supporting the filter plate. The filter plate is at least partially connected to these support surfaces by material bonding such as welding.

Abstract: A filter module has several discoid filter cells each having a central opening and stacked to form a stacked filter cell arrangement, wherein the central openings are aligned in the axial direction of the stacked filter cell arrangement. Closing rings are connected to opposed ends of the stacked filter cell arrangement and have a central opening aligned with the central openings of the filter cells. At least one tensile forces receiving element extends through the central openings of the filter cells and the closing rings and has axial ends connected to the closing rings. The closing rings have outwardly facing end faces each having a flat packing. Adaptors having a hollow-cylindrical portion and having an axial sealing surface are provided and are connectable to a further liquid-conveying component. The adaptors are connected to the closing rings such that the sealing surface presses axially against the flat packing.
