METHOD OF REDUCING VOLUME OF FEED LIQUID REQUIRED IN A POROUS HOLLOW FIBRE MEMBRANE FILTRATION SYSTEM

摘要

A method for reducing volume of feed liquid required in a porous membrane filtration system having a number of porous membranes submersed in a volume of feed liquid to be filtered is provided. The method comprises the step of providing filler elements within said volume of feed liquid to be filtered. The filler members substantially fills voids between porous membranes and occupy a space that would otherwise be occupied by the volume of feed liquid to be filtered. The filler members can be provided in the form of a number of elements which fit together to form an integral unit.
