The water flux of UF and MF membranes is dramatically increased by treatment with an aqueous solution of an organic linear polymer without detrimental decrease in other characteristics of the membrane, e.g. solute-rejection. Particular candidates for such treatment include UF and MF membranes made of PS, PES, PAN, and PVDF. The dramatic effectiveness of treatment with aqueous solutions of PEG having molecular weights between about 2000 and 6000 Daltons is shown.
