A porous support ( 1 ) for the tangential filtration of a fluid to be processed, which has at least one surface ( 3 ) oriented toward the fluid to be processed flowing in a given direction of flow, and a surface ( 1 <SUB>1</SUB>) for extraction of a fraction called the filtrate, flowing through the porous support, this support being created by modification of an initial support, characterised in that it has a reduced permeability in relation to the initial support, and which is homogeneous when one moves parallel to the surface ( 3 ) of the support oriented toward the fluid to be processed in the direction of flow of the fluid to be processed. |
