A method and an apparatus (10) for filtering and separating flow medium (11) by means of membranes (13), in a substantially pressuretight housing (14), at least one inlet (15) for the flow medium (11) to be separated, and at least one outlet (16) for permeate (18) discharge and an outlet (17) for discharged retentate (19), is described. The membranes (13) being embodied as membrane cushions, which have an opening region (131) for emergence of permeate (18) collecting in the membrane interior (137). Various partial sets of the set of membranes (13), which form a membrane stack (12), utilize different separation techniques based on the flow medium (11) so that a respective partial set 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).
A method for filtering and separating components of a flow medium by means of membranes in an apparatus having a substantially pressure tight housing in which a plurality of membranes is disposed in a stack to form a membrane stack, comprising introducing the flow medium containing components to be separated into at least one inlet for the flow medium carried into the apparatus and to be separated, and at least one outlet for permeate discharged from the apparatus and at least one outlet for discharged retentate, the membranes in the membrane stack being membrane cushions which have an opening region for emergence of the permeate collecting in the membrane cushions' interior, characterized in that in the membrane stack a first respective partial set of the plurality of membranes forming the stack has different separation techniques than a second partial set of the plurality of membranes forming the stack and are each operated with a predetermined, different pressure of the flow medium to be separated.
A method for filtering and separating flow components of a flow medium by means of membranes in an apparatus having a substantially pressure tight housing in which a plurality of membranes is disposed in a stack to form a membrane stack;
An apparatus (10) for filtering and separating components of a flow medium (11) by means of membranes (13), including a substantially pressure-tight housing (14) in which a plurality of membranes (13) is disposed in a stack, 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 permeate (18) discharged from the apparatus (10) and an outlet (17) for discharged retentate (19), the membranes (13) being membrane cushions which have an opening region (131) for emergence of the permeate (18) collecting in the membrane cushions' interior (137), characterized in that each respective partial set of the plurality of membranes (13), which form a membrane stack (12), have different separation techniques from each other partial set based on the flow medium (11) to be separated in the partial set of the plurality of membranes forming the stack.
