Abstract
A method of manufacturing a separator element for obtaining molecular and/or particulate separation by tangential flow of a fluid medium for treatment into a filtrate and a retentate, the element having a structure (2) of at least two porous rigid columns (3) made of the same material, positioned side by side to define, outside their outside walls, a volume (4) for recovering the filtrate, each column (3) presenting, internally, at least one open structure (5) for passing a flow of the fluid medium, opening out in one of the ends of the porous column for inlet of the fluid medium for treatment, and in the other end for outlet of the retentate. The element is a single-piece rigid structure (2) made as a single piece that is uniform and continuous throughout, without any bonds or exogenous additions.
