Title: SOLAR-DRIVEN AIR GAP MEMBRANE DISTILLATION SYSTEM
Abstract:
Membrane distillation system. The system includes a solar radiation absorbing porous membrane positioned to receive solar radiation to heat the membrane. A transparent cover is spaced apart from the membrane to form a channel through which a saline feed stream flows. A condensation structure is spaced apart from an opposite side of the porous membrane forming an air gap channel there between. Means are provided for coolant flow along an outside surface of the condensation structure so that distilled water will condense on the condensation structure for collection from the air gap channel.
