SEPARATION ELEMENT WITH A THREE-DIMENSIONAL CIRCULATION MATRIX FOR THE FLUID MEDIUM TO BE TREATED

摘要

The invention concerns a separation element comprising a rigid porous single-piece support member (2) having, at its periphery, a continuous perimeter wall (2i) between, on one side of the porous support member, an inlet (4) for the fluid medium to be treated and, on another side of the porous support member, an outlet (5) for the retentate, and, internally, at least one surface covered by at least one separator layer (6) and defining an open structure formed by empty spaces (3) for circulating the fluid medium to be treated. According to the invention, the empty spaces (3) for the passage of the fluid medium to be treated, which are delimited by the surface of the support member covered with the separator layer (6), are arranged in the porous support member such that they provide, within said member, at least a first circulation matrix for the fluid medium to be treated (RI), comprising at least two interconnected circuits (Rli, Rl2) for the circulation of the fluid medium between the inlet (4) and the outlet (5) the porous support member.
