    Solar pond -coupled desalination of brackish ground water has been practically demonstrated. Heat and electric power provided by the El Paso salinity-gradient solar pond was delivered to an energy-efficient portable distillation unit which also served as a waste concentrator. The separation unit consisted of a three stage/ four effect vacuum evaporator (MEMS). The MEMS used in the experiments reported is a sub-system of a larger total mobile concentrator/evaporator system known as TRANSVAP, manufactured by Licon, lnc. of Pensacola, Florida. The overall system and sub-systems are described herein. The fundamentals of evaporator technology are briefly discussed, design features are presented and operating experience is reported. Information regarding performance, water quality, productivity and energy efficiency are also featured. It is concluded that the coupling of the technologies is feasible, productive and efficient.
