The present invention relates to an element for separating, via tangential flow, a fluid medium to be treated into a filtrate and a retentate. Said separation element comprises a rigid, porous, one-piece holder (2) having a rectilinear structure, wherein a single channel (3) is provided for allowing the flow of the fluid medium to be treated. The outer surface (5) of the holder has a constant cross-section. According to the invention, the rigid, porous, one-piece holder (2) defines, projecting from the inner wall (31) of said channel (3), obstacles (9) to the flow of the fluid to be filtered, said obstacles being identical in terms of material and porous texture with regards to the holder, there being no break in the material or porous texture between the holder and the obstacles. Said obstacles (9) generate variations in the cross-sectional area of the channel. |
