Solvent removal by a forward osmosis process

The method for removing treatment of solvent from the first solution, the process comprising the following steps: Disposed in the first solution with a higher by the second solution prior to the first solution and thermal-shrinkage film, wherein the solvent from the first solution to electrodeionization of the thermal-shrinkage film is diluted to the second solution; A method for extracting solvent from the second solution, the thermal-shrinkage film has an average size at least 10 angstroms, the second solution comprising while is big and is go through the thermal-shrinkage film of the alkaline material.
