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

摘要

A separator element comprising a porous rigid single-piece substrate (2) presenting firstly, at its periphery, a perimeter wall (2₁) that is continuous between an inlet (4) for the fluid medium for treatment at one end of the porous substrate and an outlet (5) for the retentate at the other end of the porous substrate, and secondly, internally, a surface covered by a separator layer (6) and defining an open structure made up of empty spaces (3) for passing a flow of the fluid medium for treatment. The empty spaces (3) are arranged in the porous substrate so as to create within the porous substrate a first flow network (R1) for the fluid medium for treatment, having at least two interconnected flow circuits (R1₁, R1₂) for the fluid medium between the inlet (4) and the outlet (5) of the porous substrate.
