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 having a monolithic rigid porous support (2) of rectilinear structure and having a single channel (3) arranged therein for passing the flow of the fluid medium for treatment, the outside surface (5) of the support presenting a profile that is constant. According to the invention, the monolithic rigid porous support (2) defines obstacles (9) to the flow of the fluid for filtering, which obstacles extend from the inside wall (31) of said channel (3), are identical in material and porous texture to the support, and present continuity of material and of porous texture with the support, said obstacles (9) generating variations in the flow section of the channel.
