ABSTRACT:
A flexible semi-permeable tubular assembly is provided which consists essentially of a cord comprising a textile sheath which carries a semi-permeable membrane, said sheath being composed of yarns, the external surface of the sheath being compressed and flattened, the internal surface of the sheath defining an axial channel which communicates with the exterior. This assembly is particularly suitable for the concentration, separation and purification of fluids by reverse osmosis, ultra-filtration and gas permeation. The assembly combines good tensile strength with good porosity.
