Abstract
A separator element comprising a porous rigid single-piece substrate (2) made of a single porous material, and including internally at least one channel (3) for passing a flow of the fluid medium, which channel opens out in one end of the porous substrate for inlet of the fluid medium for treatment and in another end of the porous substrate for outlet of the retentate.At least one empty space (10) is arranged in the porous substrate so as to be surrounded by a portion of the material constituting the single-piece substrate (2) either completely so as to form a closed cavity or partially so as to form a cavity (101) that opens out locally through the peripheral envelope (22) of the substrate via a passage (102) of section smaller than the section of the cavity (101).
