    摘要： An ultrafiltration device comprising an anisotropic ultrafiltration membrane tube secured around a liquid-impermeable cylindrical core. The core has a plurality of peripherally spaced, axial ribs along its outer surface, which define therebetween a plurality of axial grooves. The anisotropic membrane comprises a polymer film comprising a porous support layer and a less porous barrier layer integral therewith at one face of the support layer, and the barrier layer of the membrane tube is in contact with the ribs, so that the membrane defines, with the grooves, a plurality of axially extending channels adjacent this barrier layer and having a fluid inlet at one end and a fluid outlet at the other.

    摘要： A process for making a rewettable microporous membrane, advantageously a rewettable and highly anisotropic membrane, comprising the step of filling the inner surfaces of the micropores with the vapor or gas of a volatile water-miscible compound having low surface tension and viscosity; the compound is then deposited on the micropore surface by a condensing step. Methanol and like compounds are particularly advantageous compounds for use in forming the rewettable membrane.

    摘要： THIS INVENTION RELATES TO A NOVEL PROCESS FOR FORMING IMPORVED POLYMERIC ANISOTROPIC MEMBRANES COMPRISING THE ADDITIONAL STEP OF SUBJECTING A CAST POLYMER FILM SUITABLE FOR FORMATION OF SUCH AN ANISOTROPIC MEMBRANE TO AN EVAPORATION STEP PRIOR TO PRECIPITATION OF THE MEMBRANE, SAID EVAPORATIVE STEP CONTROLLED TO SELECTIVELY EVAPORATE SOLVENT FROM THE SURFACE OF SAID FILM AND THEREBY SELECTIVELY INCREASE THE POLYMER CONCENTRATION AT THE SURFACE OF SAID FILM. THE IMPROVED MEMBRANES FORMED BY THE PROCESS OF THE INSTANT INVENTION ARE CHARACTERIZED BY IMPROVED REJECTION CHARACTERISTICS WHILE RETAINING LIQUID FLUX CHARACTERISTICS WHICH ARE SURPRISINGLY HIGH IN VIEW OF THE REJECTION CHARACTERISTICS.

    摘要： An ultrafiltration apparatus comprising a reservoir for receiving materials to be ultrafiltered, a self-contained autocontrolling, gas-pressurizing means to pressurize said reservoir, a removable base member to allow easy filling and cleaning of the apparatus, and a free piston mounted in the reservoir forming a barrier between the pressurizing gas and material being processed and also forming a valve effective against leakage when the reservoir is being filled from the bottom.
