<p>A thermal desalination process comprising: introducing a feed solution into a thermal separation unit, distilling the feed solution in the thermal separation unit to produce a distillate stream and a residual stream having a higher solute concentration than the feed solution, contacting a portion of the residual stream from the thermal separation unit with one side of a selectively permeable membrane, contacting the opposite side of the selectively permeable membrane with a portion of the feed solution, such that water flows across the membrane to dilute the residual stream by direct osmosis, and introducing at least a portion of the diluted residual stream into the thermal separation unit.</p> |
