摘要

POROUS AND MEMBRANE SUPPORT FOR TANGENTIAL FILTRATION OF A TREATED FLUID AND MANUFACTURING PROCESS OF A POROUS SUPPORT. Porous support (1) for tangential filtration of a fluid to be treated having at least one surface (3) oriented to the fluid to be treated circulating in a direction of movement and an outlet surface (1 ~ 1 ~) for a fraction called permeate that crosses the porous support, this support being obtained by modification of an initial support, characterized by the fact that it has a reduced permeability, relative to the initial support, and homogeneous when moving parallel to the surface (3) of the support. oriented to the fluid to be treated, according to the direction of circulation of the fluid to be treated
