Apparatus for filtering and separating fluid media into a permeate and a retentate

摘要

An apparatus (10) for filtering and separating fluid media (16) into a permeate (17) and a retentate (18) is proposed, in particular filter elements (12) acting by the principle of reverse osmosis, ultrafiltration and microfiltration which are surrounded by the fluid medium (16) and are arranged in a closed shell forming a filter element stack (13). The filter element stack (13) comprising essentially planar filter elements (12) which are constructed in the manner of a membrane cushion is rotated during the filter or separation process about a filter element stack (13) axis (130) running essentially orthogonally to the surface (120) of the filter elements (12). <IMAGE>
