The invention relates more closely to a so-called drum filter, the basic construction of which comprises a vessel, to which suspension being thickened is supplied and in which vessel a wire-surfaced cylinder rotates. The drum filter in accordance with the present invention is characterized in that its filtrate compartments (20) comprise a bottom part (28, 30) and a side surface (32), which is provided with a lip or bending (34) extending towards the inside of the compartment (20) at the edge opposite relative to the bottom plane, which lip (34) prevents the filtrate from escaping from the compartment (20) back through the wire surface, when the compartment (20) is inclined.
