Abstract

A method of extracting water from a source aqueous solution (7) comprising the step of, a) providing a composite structure (1) of two layers (2, 3), each layer being of sheet form having two faces, a first layer (2) of which is a barrier to a liquid, permeable to water vapour but impermeable to non-volatile species, and a second layer (3) of which is highly resistive to fluid flow and permeable to water and to small species dissolved in water, b) providing channels defined at least in part by the surfaces (4, 6) of the composite structure (1), c) providing flow of a desiccant fluid (8) within one or more channels, d) flowing the source aqueous solution (7) within one or more other channels. A specific embodiment is the combination of osmotic distillation with (electro) dialysis integrally incorporated in a single module.
