Abstract of the Disclosure The flux rate of ultrafiltration membranes is markedly improved by the presence of inert, water-insoluble, impervious particles, particularly of metals and their alloys, distributed wholly within the membrane. The particles are particularly effective in the region adjacent the interface of the membrane with a support surface and may be distributed previously in the casting dope, or applied in a thin coating to the surface on which the membrane is subsequently prepared by casting from the dope. The membrane is in flat, tubular or filamentary form.
