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.
