APPARATUS FOR FILTERING AND SEPARATING FLOW MEDIA

摘要

In an apparatus for filtering and separating a flow medium by way of membranes disposed in a pressurized housing, which has an inlet for supplying the flow medium to the housing and outlets for discharging the retentate and the permeate from the housing, the membrane structure comprises a central permeate collection and discharge structure to which a plurality of mem- brane pillows are connected so as to extend therefrom in a spi- ral pattern and each membrane pillow is in communication with a permeate inlet opening in the permeate collection and discharge structure through which permeate is conducted out of the mem- brane pillow into the central permeate collection and discharge structure and to the retentate outlet.
