    Abstract: Apparatus (8) for filtering, clarifying or polishing, a liquid flow containing finely divided solids. In the apparatus (8), the liquid flow to be filtered is directed to the outer surface of a filter element (3) with high speed and in tangential direction, and thereby, influenced by the generated shearing force, part of the liquid penetrates the filter element (3) and is filtered. More precisely, the apparatus (8) includes a cross-flow tube (2) having a circular cylindrical shape and having apertures directed substantially in tangential direction towards the outer surface of the filter element (3). A method for removing finely divided solids from a liquid flow using such apparatus is also described.
