ABSTRACT:
A device for filtering and separating a flow medium by reverse osmosis, micro filtration, ultra filtration, or nano filtration has a pressure-tight housing having an inlet for the flow medium and a first outlet for the retentate and a second outlet for the permeate. A plurality of stacked units comprised of spaced apart membrane filter elements is provided, wherein the membrane filter elements are stacked atop one another to form a stack. The stacked units are sequentially arranged in the housing. The flow medium flows in sequence through the stacked units. Each one of the membrane filter elements includes areal outer membrane elements and an areal stabilizing element positioned between the areal outer membrane elements.
