A filter assembly (1), for a water or sewage processing installation, is a rotating filter (2) within a filter chamber (3) with a base (4) shaped as a hollow semi-cylinder (41) to match the rotating filter contour, around a common axis (21). The filter chamber is emptied through a structured section (42) at the base. For periodic cleaning, the filter chamber is disconnected from water feeds, and any water in it is pumped or blown out. The chamber is filled with a cleaning fluid, to a level below the rotating axis, and the filter is rotated, and the cleaning fluid is pumped out.
