An apparatus for compressing and washing contaminated raked-off or screened material, particularly in sewage treatment plants, having a screw conveyor device with horizontal shafts (2, 3). There is a washing zone (33) with washer nozzles (34, 38) and compacting zones (21, 47) arranged before and after the washing zone. The washing zone (33) is divided into two sections (31, 32) adjacent to each other, in each of which a defined water level (35), occupying approx. 1/4 to 1/3 of the height of the cross-section of the housing (1), is present. In the first section (31) of the washing zone (33), the washer nozzles (34, 36) are arranged both above and below the water level (35). In the second section (32) of the washing zone (33), the housing for the screw conveyor device is provided with openings (40) arranged laterally to define the water level.
