Abstract
A drum filter 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 curved portion (34) extending towards the inside of the compartment (20) from the edge of the side surface opposite the bottom part. The lip (34) prevents the filtrate from escaping from the compartment (20) back through the wire surface, when the drum filter (20) is rotated.
