Abstract
A device for filtering and separating a flow medium by reverse osmosis, microfiltration, ultrafiltration or nanofiltration has a pressure-tight housing with 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 spacer elements and membrane filter elements is provided. The spacer elements and the membrane filter elements are stacked alternatingly atop one another to form a stack. The stacked units further comprise two receptacle parts forming a receptacle for enclosing a stack of spacer elements and membrane filter elements. The stacked units are positioned adjacent to one another in the housing. The flow medium flows in sequence through the stacked units.
