Abstract
This document describes systems and methods for treating and recovering water from feed solutions using a multilayer module with an expansion chamber. The multilayer module comprises a feed spacer layer, a permeate spacer layer and a membrane layer, wherein water vapor evaporated from the feed solution in the feed spacer passes through the membrane layer into the permeate spacer layer. The expansion chamber receives the water vapor from the permeate spacer layer and the feed solution from the feed spacer layer.
