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.
