Abstract

A filter element includes an integrated permeate channel membrane (4) which has a flexible structure and includes an upper and lower membrane layer and a substrate material for supporting the membrane layers. The substrate is a 3D spacer fabric having an upper and a lower fabric surface, tied together and spaced apart by monofilament threads at a predefined distance. A frame system supports the membrane and sealing the integrated permeate channel at the edge of the membrane. The frame system includes a first frame profile and a second frame profile each of them having form and dimensions capable of surrounding the membrane. Each of the first and second frame profiles has inner parts and outer parts with the membrane (4) interposed between the first frame profile and the second frame profile. A filter module includes filter elements.
