    摘要： A membrane filtration device, for withdrawing permeate from a liquid substrate, includes a first solid body (41u); a second solid body (41b); and a plurality of hollow fiber membranes (42) potted in the solid bodies such that the peripheries of the membranes are bounded by an elongated rectangular shape and such that the membranes have open ends flush with or protruding from a permeate discharging face of one or both solid bodies. A permeate collection means (43u, 43b) is arranged to collect permeate in fluid communication with the permeate-discharging face of each solid body (41u, 41b) that has a permeate-discharging face. The membranes (42), the solid bodies (41u, 41b) and the permeate collection means (43u, 43b) together form a submersible assembly. The first solid body (41u) is upper and disposed in vertically spaced-apart relationship above the second solid body (41b). The opposed faces of the solid bodies (41u, 41b) are separated by a vertical distance and the membranes (42) have a length from 0.1% to less than 5% greater than the vertical distance between the opposed faces of the solid bodies (41u, 41b).

    摘要： A method for stretching a hollow fibre while making a stretched filtering membrane from a precursor involves wrapping the hollow fibre around a structure and modifying the structure such that at least portions of the hollow fibre are forced to elongated. For example, the hollow fibre may be wrapped around two or more supports and the distance between adjacent supports increased. This produces first portions of the hollow fibre stretched to a first elongation and porous to a first porosity and second portions of the hollow fibre that are not stretched or are stretched to a second elongation less than the first elongation and that remain non-porous or become porous to a second porosity which is less than the first porosity. The membrane may be made into a module with second portions of the membranes located at points where the membranes exit the potting material or at turns in loops of the fibres, if any. In various embodiments, the fibre is potted into modules before or after it is stretched. Some methods of potting involve applying a hot melt adhesive to the second portions. Some embodiments are made entirely of thermoplastic material and can be easily recycled.

    摘要： An apparatus is described for cleaning or inhibiting the fouling of a plurality of membrane modules 20 immersed in tank water 18 in a tank 12. Air is supplied through aerators 38 to produce a flow of bubbles 36 effective to clean or inhibit fouling of the membrane modules. The flow of air is alternated between a higher flow rate and a lower flow rate, the lower flow rate being less than one half of the higher flow rate, in repeated cycles of not more than 120 seconds in duration while the permeate is withdrawn through the membrane modules 20. This produces transient flow conditions in the tank water 18, the tank water 18 being accelerated or decelerated for much of each cycle so that it is rarely in a steady state during permeation. This gives rise to efficient cleaning of the membranes without overloading the aerator system. The flow rates are controlled by a set of valves 254 and a controller 256.

    摘要： To pot membranes in a header, a dense, viscous liquid, suspension or, preferably, a thixotropic, water soluble gel, is placed in a header pan in space reserved for a permeate channel. A plurality of hollow fibre membranes are collected together and their open ends are inserted into the gel. A fixing liquid, typically a resin, is placed over the gel. The fixing liquid surrounds each membrane and then solidifies, simultaneously sealing the outer surfaces of the membranes and forming a plug in the opening of the header to complete the permeate channel. After the fixing liquid has solidified, the gel is removed by various means. The space initially occupied by the gel becomes part of the permeate channel after the gel is removed. In one embodiment, membranes are grouped by a cushioning adhesive which later surrounds the membranes where they exit the completed header.
