Abstract
A filtering element for the filtration of a fluid medium comprises a rigid porous support of cylindrical shape having a longitudinal central axis (A) and a plurality of channels for the circulation of the fluid medium to be filtered and collection of filtrate on the periphery of the support. The channels are arranged in the support parallel to its central axis central (A) and define at least three filtering zones which are distributed concentrically and separated from each other by a continuous porous zone. The mean thickness of the porous zone (Z) closest to the central axis (A) is smaller than the mean thickness of the porous zone (Z) the closest to the periphery of the support () and, in the direction moving away from the central axis (A) of the support towards its periphery, the mean thickness of a porous zone is either identical to the next or smaller.
