ABSTRACT:
A filtration unit for the separation of substances from liquids utilizes a rotatable cylindrical module with a permeable wall disposed within a housing. A filter element which has at least one band of microporous membrane adsorber having a specific adsorption affinity for the substances to be separated is disposed within the cylindrical module so that the membrane absorber is abutted to the cylindrical module. The filter element encircles the feed inlet and can be in the form of an endless loop. A permeate plenum lies between the cylindrical module and the housing. The cylindrical module includes a liquid impermeable end cap which is provided with a coupling member adapted for connection to a drive of variable rotational speed.
