Abstract
A membrane module is disclosed which comprises at least one elongated, planar membrane element which is composed of two membranes aligned opposite one another so as to define a closed cavity into which active surfaces of both membranes face. At both ends of the membrane element, separate conduits attached to the two membranes are in communication with the cavity, such that the feed flow from one conduit to the other through the cavity is radial, relative to the membrane element. The membrane element can be spirally wound around one or both of the conduits.
