Abstract: A hollow fibre membrane having a coiled, a hemihelix, a helical or an undulated native form, in which the membrane can be stretched by up to 4-times its original length with no plastic deformation, and wherein the native form of the membrane is produced by the asymmetric flow of liquid polymer through an opening of a die or nozzle.

Abstract: The invention relates to the design of an enclosure for a membrane aeration module, which incorporates a reversible, low-pressure, air-lift pump to encourage a vertical water flow through and between the membranes in the module. These enclosed membrane modules are suitable for use in membrane aerated biofilm reactors, which are used to treat water or wastewater.

Abstract: A device for treating wastewater liquids, the device comprising a housing (4) incorporating a membrane supported biofilm reactor (MSBR) (2) of the type comprising a lumen containing a gas phase, a liquid phase, and a gas permeable membrane (20) providing an interface between the gas and liquid phases; and a means (6) for mixing the wastewater liquids in the device, wherein the means (6) for mixing the wastewater liquids is configured to create a mixing intensity sufficient to ensure that there is contact between the membrane (20) and the wastewater liquid to be treated.
Abstract: A membrane fibre bunch for use in a membrane-aerated biofilm reactor (MABR), the membrane fibre bunch comprising: a group of membrane fibres arranged as a bunch (4) of vertical or horizontal membrane fibres attached at either end to an gas supply manifold (8) within the housing, with each fibre having a lumen containing a gas phase; and a means for connecting the group of membrane fibres so that the gas can flow within the lumen of the membrane; wherein the group of membrane fibres are maintained in position by a connector or overmold (10), the connector or overmold configured to maintain the group of membrane fibres (2) in a spaced-apart configuration from one another and the cross-section of the connector/overmold being of non-circular shape such as ellipsoidal, star-shape etc.
