摘要

Tangential flow filter for separating solids from a medium comprises a coarsely porous support (1) containing flow channels (2) for the solids-containing medium, and finely porous membranes in the channels. The channels have a cross-section with at least four wall sections, pairs of opposite walls being parallel to each other, and are joined together by segments of a circle.
