摘要： Provided are a composite forward osmosis membrane and a membrane module including same. The composite forward osmosis membrane reduces salt back-diffusion and has high water-permeability, or is made of readily available materials and can be easily manufactured. Even when used at high pressure, separation between a substrate membrane support layer and a separation active layer does not occur in the composite forward osmosis membrane, and thus the composite forward osmosis membrane exhibits stable high performance. This composite forward osmosis membrane is composed of a hollow-strand porous polymer substrate membrane, wherein a separation active layer is present on the inner surface or outer surface of the substrate membrane, an inner columnar void layer having a predetermined shape is present at a predetermined thickness with respect to the thickness of the substrate membrane from the inner surface toward the center of the substrate membrane, and an outer columnar void layer is present at a predetermined thickness with respect to the thickness of the membrane from the outer surface toward the center of the substrate membrane. The substrate membrane has a water permeability F1 within a predetermined range and a rejection ratio R within a predetermined range, or the substrate membrane support layer contains a polyether sulfone having an OH group. The membrane has a thickness within a predetermined range and a compression strength within a predetermined range.

摘要： A selectively ion-adsorptive, porous membrane comprising a membranous, porous resin matrix of a hydrophobic polyolefin or a hydrophobic copolymer of an olefin and a halogenated olefin and a plurality of side chains chemically bonded to both surfaces, which in turn are inclusive of pore wall surfaces, of the membranous porous resin matrix is disclosed. The side chains collectively contain both neutral hydroxyl groups and ion exchange groups. The selectively ion-adsorptive, porous membrane is suitable for use in selective purification or selective removal of desired ionic substances including not only ionic inorganic substances but also an ionic organic substances, such as a protein and an amino acid, on a commercial scale. Further, the selectively ion-adsorptive, porous membrane has not only excellent heat resistance, but also excellent mechanical strength. Therefore, the porous membrane of the present invention can advantageously be used for industrial applications, such as pharmacy, fermentation and the like.
