A filter (20) configured to separate the solid components and the liquid components from a slurry. The filter (20) includes a plurality of filter plate assemblies (46) that cooperate to define a plurality of filter chambers (70), each defining a perimeter (96) having an open section (98) when the filter plates (68) are in a closed position relative to one another. Each filter plate assembly (46) includes a closure (104) configured to close the open section (98). Preferably, the closures (104) are movable to an open position to permit a particulate cake to be removed from the filter chambers (70) without separating the filter plates (68).

An arrangement of a filter plate for a filter press and of a sealing device. The filter plate has a contact surface for contact with another filler plate, which extends in parallel to a plane formed by the filter plate, and at least one channel opening for forming a channel. The channel opening passes through the filter plate perpendicularly to the plane. Furthermore, it is delimited by a channel surface of the filter plate. The filter plate has an annular recess with a first annular boundary surface. The sealing device has an elastic ring seal and a clamping ring, wherein the elastic ring seal has a second annular boundary surface which corresponds to the first annular boundary surface, and the clamping ring can be inserted into the annular recess such that the elastic ring seal is clamped between the clamping ring and the first annular boundary surface.

A method of operating a filter press, wherein filter material is fed into a filter chamber so as to form a filter cake between at least two sides of a flexible said filter medium. Filtrate is received from the filter chamber and the filter cake formed the filter chamber is discharged. Prior to discharging the filter cake, compression is applied on the filter cake formed within the filter chamber by providing compression fluid gas at a compression pressure exceeding a prevailing pressure within the filter chamber, directly on a side of the filter medium exterior to the filter chamber, so as to exert said compression pressure directly on said side of the filter medium, thereby causing the filter medium to yield against the filter cake.

A membrane plate, a filter plate, and a filter press. The membrane plate is outfitted with a filter element on top of the membrane on both side surfaces, and the membrane plate has retaining elements at a distance from the margin on which the filter elements are removably secured. The filter plate also has retaining elements at a distance from the margin on which the filter elements are removably secured.

A recess plate designed for use in a filter device for filtering a suspension includes a stationary head piece and a movable end piece, and a pack including copies of the recess plate, having a filter chamber inside the pack, adjoining the recess plate, having a first pipe for filling the suspension into the filter chamber, having a filter cloth for collecting a solid content out of the suspension, and having a second pipe for discharging a liquid fraction of the suspension out of the filter chamber as a filtrate, wherein the filter device may be closed before filtering by forcing the end piece in direction of the head piece, and opened after filtering by releasing the end piece, and moving the end piece away from the head piece for removing the filter cake from the filter cloth.
