An apparatus designed to separate mixtures of materials by use of a stack of spaced membrane elements (11) in the form of membrane cells having bore (112) through which the permeate (130) is discharged. The device (10) includes a feed inlet (14) for the mixture plus discharge outlets (16) for the retentate (17) and permeate (13), and the mixture flowing over the surfaces (110, 11, 180, 181) of the membrane elements (11) in chambers (150) between element (18). Fitted between each pair of membrane elements (11) or between the membrane (11) and deflection (18) elements is an annular support element (19) which surrounds the bore (112) through the membrane element (11) or deflection element (18), the seal between the support element (19) and the membrane (11) or deflection (18) element being formed by a sealing element (191) fitted round the outer circumference (190) of the support element (19).

[ We claim:] [1.] An apparatus for separating components of mixtures of materials having membrane elements which are spaced mutually apart and superposed, which membrane elements are in the form of pockets, flattened tubes, which membrane elements have a bore to allow outflow of the permeate, a feed opening to admit the materials, and outlet openings for outflow of the retentate and the permeate, such that the mixture flows in an essentially laminar flow from the feed opening to the outlet openings along surfaces of flow chambers formed between successive membrane elements and between a membrane element and a guide element having a bore the improvement comprising a ring-shaped support element disposed between each successive membrane elements, and between each guide element and a neighboring membrane element which support element extends around the bore of the membrane element and guide element, and a sealing element disposed at the outer periphery of the support element forming a seal between the support element and the membrane element and between the support element and the guide element.
