Abstract

In a backwash filter, in particular a utility water filter, having at least one filter cartridge composed of annular discs arranged one above the other, that is composed of a regular sequence of plate discs and flat discs identical among themselves, the plate discs provided with recessed bases each forming, together with a flat disc supported on spacers arranged on one side of its plate edge, an annular gap which is interrupted by radial bridges on the recess edge impinged by the filter liquid and which is expandable during the filter backwashing by elastic deformation of one of the interacting annular discs against an open surface formed by a recessed base of a disc, according to the invention it is provided that an elastically deformable flat disc is assigned to each plate disc on its plate edge furnished with the spacers, which elastically deformable flat disc lies flat on the plate edge of the following plate disc whose recessed base forms the open surface for the deformation of the flat disc.
