Pervaporation Composite Membrane for Aqueous Solution Separation and Methods for Using the Same

In one embodiment, a membrane comprises: a nonporous, hydrophobic selective layer configured to be on a feed solution side of the membrane and polyethylene layer configured to be on a permeate side of the membrane, wherein the membrane is configured to selectively separate an organic component from an aqueous solution. In some embodiments, the method for separating an organic component from an aqueous stream can comprise: contacting a nonporous, hydrophobic selective layer of a membrane with the aqueous stream comprising the organic component, creating a vacuum on the side of the membrane comprising the support layer, permeating the organic component through the membrane into an exit chamber, and removing the organic component permeate from the exit chamber.
