Estimating the term…
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.
An integral permeate channel membrane, comprising a permeate channel consisting of a 3D spacer fabric having an upper and a lower fabric surface tied together and spaced apart by monofilament threads at a predefined distance, said permeate channel being interposed between two membrane layers, wherein said membrane layers are linked at a multitude of points with said upper and lower fabric surfaces.
A method for providing a integrated permeate channel membrane, comprising the steps of:
