A membrane has a permeate channel including a 3D spacer fabric having an upper and a lower fabric surface ( 2,3 ) spaced apart by monofilament thread ( 4 ) at a predefined distance, the permeate channel being interposed between two membrane layers ( 12, 13 ), wherein the membrane layers are linked at a multitude of points with the upper and lower fabric surfaces to form an integral structure with a high bonding strength suitable for backflush operations. A method provides an integrated permeate channel membrane, including the steps of:-Providing a 3D spacer fabric having 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 the upper and the lower surface fabric.
