    摘要: Disclosed are seamless membrane bags, for example, a membrane bag comprising a spacer fabric and a volume for permeate collection, the spacer fabric comprising a first part and a second part that are spaced apart and tied together at a predefined distance by monofilament thread and the first and second parts are at least partially embedded with membrane substance and the volume for permeate collection is interposed between the first and second parts. The membrane substance embeds portions of the monofilament thread and fills the spacer fabric along the border of the membrane bag. The membrane substance completely enclosing the volume is seamless. Also disclosed are processes for producing such bags, a filtration unit comprising such a membrane bag, and their uses in the separation of fluids, vapors and particles.

    摘要: A device for the filtration of liquids includes membrane curtains (2), each curtain being formed of a singular row of capillary membranes (5). The device has at least one bottom header (3) provided at a lower end of the membrane curtains (lower end of the capillary membranes) and linked to the capillary membranes of at least one membrane curtain and an individual top header (4) for each membrane curtain. The top header is provided at an upper end of the membrane curtain and is linked to the capillary membranes thereof. Top headers of adjacent membrane curtains (41, 42) are arranged at different heights and the capillary membranes (5) of the adjacent membrane curtains (2) have different lengths.

    摘要: A method of manufacturing a reinforced tubular membrane comprises the steps of manufacturing the tubular support from monofilament thread, impregnating the support with membrane dope and adjusting the inner and the outer diameter of the membrane. A coating apparatus comprises a casting bob and an orifice to adjust respectively the inner and outer diameter of the membrane. A tubular reinforced polymeric membrane comprises a tubular support and membrane substance. The tubular support is made of monofilament thread and has a sufficiently open structure (openings larger than 0.1 mm). Touching and/or engaging parts of the thread may be linked prior to impregnating the support with membrane dope. The support may comprise loops of the monofilament thread, which are also linked.
