Thermal Desalination using MEMS and Salinity-Gradient Solar Pond Technology
University of Texas at El Paso; El Paso TX.
August 2002
Report #80 - Abstract -
MEMS (multi-effect, multi-stage) flash desalination (distillation) driven by thermal energy derived from a salinity-gradient solar pond is investigated in this study for the purpose of improving the thermodynamic efficiency and economics of this technology.
Three major tasks are performed:
(1) a MEMS unit is tested under various operating conditions at the El Paso solar pond site;
(2) the major operation and maintenance procedures of the salinity-gradient solar pond coupled with the MEMS operation is studied; and
(3) previous test data on a 24-stage, falling-film flash distillation unit (known as the Spinflash) is analyzed and compared with the performance of the MEMS unit.
The data and information obtained from this investigation is applicable to a variety of thermal desalination processes using other solar options and/or waste heat.
