TITLE OF THE INVENTION: APPARATUS FOR SEPARATING MIXTURES BY SPACED STACKED MEMBRANE ELEMENTS An apparatus for separating mixtures by membrane elements, which are spaced and arranged into a membrane element stack via a supporting frame that comprises outer and inner rings, whereby the membrane elements have a boring for draining a permeating substance. The boring has an inlet port for introducing the mixture into the apparatus and an outlet port for the retained substance as well as the permeating substance. In mixture compartments, formed by the membrane elements between said inner and outer rings, the mixture to be separated flows past areas of the membrane elements, having a constant effectiveness, whereby the flow cross-sections of the mixture compartments vary from the introduction port to the exit port of the membrane stack. All inner and outer rings of the membrane element stack have identical dimensions, and the differing flow cross-sections in the mixture compartments are adjustable at least by varying the width of the membrane elements.
