    摘要： Provided is a flow path material for a liquid separation apparatus, which is less likely to collapse upon the application of a high pressure to the flow path material and causes a lower reduction of the flow rate. The flow path material for a liquid separation apparatus includes a tricot fabric containing thermoplastic core-sheath composite fibers each made of two kinds of polyester resins having different melting points or softening points. The flow path material for a liquid separation apparatus is configured such that: in the thermoplastic core-sheath composite fibers, a high-melting-point component is placed in the core, while a low-melting-point component is placed in the sheath; the tricot fabric is a tricot knitted fabric knitted with a two-guide-reed knitting machine using the thermoplastic core-sheath composite fibers as a front yarn and a back yarn and is rigidified by the thermoplastic core-sheath composite fibers being bonded to each other; the tricot fabric has a wale density of 45 to 70 yarns/inch (2.54 cm) and a course density of 40 to 70 yarns/inch (2.54 cm); and, when the tricot fabric is heat-pressed at 90° C. and 4.0 MPa for 3 minutes, the percentage of change in the thickness of the tricot fabric before and after pressing is 10% or less.

    摘要： A by-pass control sleeve has circumferential protrusions along its outer surface. The protrusions of the by-pass control sleeve may be distributed along the length of the sleeve with constant diameter sections of the sleeve therebetween. The protrusions may be asymmetrical and/or may have a steep and/or concave curved forward face. A method of making a by-pass control sleeve comprises molding the protrusions on an outer surface of the sleeve. A method of installing the by-pass control sleeve comprises sliding the sleeve onto an end of a spiral wound membrane element. A combination of the by-pass control sleeve fixed to the spiral wound membrane element may be installed in a pressure housing.

    摘要： Disclosed is a membrane filter unit which includes:



    a filter case for housing a membrane; an inner tube housing a wastewater chamber and a hollow core tube, a middle tube housing a pure water chamber; the hollow core tube having a top opening at a top end and a bottom opening at a bottom end, and having a water collecting channel on its outer wall and positioned coaxially inside the case, wherein the top opening is adapted to open into the wastewater chamber; and a membrane having an inner peripheral surface, a top outer peripheral surface, a bottom outer peripheral surface and a side outer peripheral surface; and arranged around the core tube such that the inner peripheral surface of the membrane is spirally wound around the core tube and the side outer peripheral surface is capable of permeation of raw water through its surface.
