Spacer for Membrane Modules, a Membrane Module and Uses Thereof

A spacer for membrane modules comprising;

• at least one inserted element and support members selected from at least one member of the group consisting of support surface units, solid surface material having perforations, porous surface materials, composite surface materials having perforations or pores or combinations thereof, sandwich surface materials having perforations or pores, or combinations thereof, the support members being spaced apart by the at least one inserted element and forming flow channels between the support members and the inserted element for guiding permeates to the at least one permeate collection device, and the at least one permeate collection device being in substantially perpendicular contact with the flow channels, for guiding concentrate through the flow channel out of the membrane module.

A membrane module comprising a permeate collection device, membrane films and at least one spacer, wherein the membrane films are attached on both sides of the at least one spacer.
