Abstract Described herein are thin film composite (TFC) membranes, for use in forward osmosis (FO) and pressure reduced osmosis (PRO) processes. The membrane is comprised of two layers: a composite layer combining a backing layer and a porous, polymer-based support into a single layer, and a rejection layer disposed on top of the composite layer. The membrane of the invention exhibits high water flux values for FO processes, is durable, may be readily manufactured using typical membrane manufacturing processes, such as spiral winding and plate and frame processes, and has sufficient mechanical stability to handle the final membrane product.
