IMPROVED MICROPOROUS MEMBRANE FILTRATION ASSEMBLY

摘要

A filter assembly (1) comprising an elongate housing (2) having therein a plurality of discrete filter bundle lengths (3) disposed end to end in a series configuration. Each filter bundle length (3) comprises a multitude of microporous polymeric hollow fibres of the kind wherein feed to be filtered is fed to the outside of the bundle of fibres and permeate is extracted from one or both permeate discharge ends (4) of the fibre lumens. The system also includes one or more longitudinally extending feed passages (6 and 7) and one or more longitudinally extending permeate return passages, each of the permeate return passages being in fluid flow communication with each of the permeate discharge ends (4) of the fibre lumens, desirably via connecting passages (9).
