ABSTRACT:
In order to provide a device for treating a fluid containing solids which has been flushed back from a reversible flow filter, comprising a sedimentation device for separating solids from the flushed back fluid by a process of sedimentation in a sediment collecting region which enables solids to be removed in a manner free from filter-aids and which exhibits as small a degree of fluid loss as possible, it is proposed that the sediment collecting region is arranged to be subjected to a positive pressure and/or a negative pressure in order to remove residual fluid from the sediment collecting region.
