Integrated permeate channel membrane

摘要

The present invention is related to a membrane, comprising a permeate channel consisting of a 3D spacer fabric having an upper and a lower fabric surface (2,3) spaced apart by monofilament thread (4) at a predefined distance, said permeate channel being interposed between two membrane layers (12,13), wherein said membrane layers are linked at a multitude of points with said upper and lower fabric surfaces to form an integral structure with a high bonding strength suitable for backflush operation. The present invention further relates to a method for providing an integrated permeate channel membrane comprising the steps of: Providing a 3D spacer fabric comprising an upper and lower surface fabric (2,3) spaced apart by monofilament thread (4) at a predefined distance, and Applying a membrane layer to both said upper and said lower surface fabric.
