Abstract
The present invention relates to a tangential flow separator element for separating a fluid medium for treatment into a filtrate and a retentate, said separator element comprising a monolithic rigid porous support (2) of rectilinear structure with a plurality of channels (3) formed therein for passing a flow of the fluid medium for treatment between an inlet (6) and an outlet (7) for the retentate, in order to recover a filtrate from the outside surface (5) of the support.According to the invention, the monolithic rigid porous support (2) defines obstacles (9) to the flow of the fluid for treatment, which obstacles extend from the inside walls (31) of said channels, are identical in material and porous texture to the support, and present continuity of material and of porous texture with the support, the obstacles (9) generating variations in the flow sections of the channels.
