1. A dissolved-solids-bearing water evaporator for producing fresh water by evaporation of dissolved-solids-bearing water and condensation of vapor generated by such evaporation to produce a stream of fresh water, comprising, in combination:

  • a housing having a dissolved-solids-bearing water inlet and a dissolved-solids-bearing water outlet;

    a plurality of plate heat exchange elements within the housing, each plate element having a lower internal space, means for introducing a heating medium into the lower internal space and means for discharging the heating medium from the lower internal space, means for introducing vapor derived from the evaporation of dissolved-solids-bearing water within the housing into an upper internal space and means for discharging fresh water from within the upper internal space, said upper and lower internal spaces being separated by a transverse partition; and

    entrainment separator means for preventing water entrained by vapor derived from the evaporation of dissolved-solids-bearing water from entering the upper internal space.
