A filter press, including a housing, which receives a liquid to be filtered that contains particles to be separated off, and a pressing device arranged in the housing for pressing the liquid through a filter device, wherein the pressing device, which rotates about a vertical axis, has at least one cross-sectionally round pressing element which rotates about an axis of rotation situated at an angle to the vertical axis and which has an outer casing formed from an elastic material, by which the pressing element rolls on the filter device, wherein the filter device includes a filter and, upstream of the filter, a filter plate which has a plurality of apertures which are open toward the pressing element and each of which has a cross section reducing toward the filter.

A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.
