The receptacle for the sludge contains a sieve surface comprising openings for the passage of liquid. The sieve surface, for its part, is substantially circular can be rotated about an axis (21) running vertically to the sieve surface. The axis (21) of the sieve surface (2) is inclined relative to a horizontal line and is caused to rotate by a drive device (3). The disk-shaped sieve surface (2) is arranged in a container (11) comprising a bottom (13) and a side wall (12) through which side wall a supply line (4) for the sludge and an outlet (41) for the separated water run.
