<p>The invention relates to a method and an apparatus (10) for filtering and separating flow media(11) by means of membranes (13), including a substantially pressuretight housing (14) in which a plurality of membranes (13) is disposed, at least one inlet (15) for the flow medium (11) carried into the apparatus (10) and to be separated, and at least one outlet (16) for the permeate (18) discharged from the apparatus (10) and an outlet (17) for the discharged retentate (19), the membranes (13) being embodied on the order of membrane cushions, which have an opening region (131) for the emergence of the permeate (18) collecting in the membrane interior (137). Various partial sets of the set of membranes (13), which form a membrane stack (12), are embodied for different separation areas with a view to the flow medium (11) to be separated, so that a respective partial set of the set of membranes (13) the different separation areas are each operated with a predetermined, different pressure of the medium (11) to be separated or with a different vacuum on the permeate side of the membranes (13).</p> |
