The main purpose of this study is to develop a sustainable membrane distillation desalination (SMDD) system. Direct contact membrane distillation (DCMD) unit is connected directly to salinity gradient solar pond (SGSP). The used system contains 0.1047 m2 of hydrophobic hydroporos PTFE membrane module and a cooling pipe running all over the pond water surface. This system uses hot and high concentrated saline water that is extracted from non-convictive zone (NCZ) as a feed solution. Then, the brine discharges at the lower convictive zone (LCZ) of the solar pond. Therefore, if the saturated brine can be used to produce salts, there will not be any brine left over which may lead to low liquid discharge desalination. Furthermore, the cooling system pipe of permeate water is used as a wave suppression system where it is floating over the pond water surface. These waves are caused by wind driven currents which is responsible for undesirable pond surface mixing. The results are analysed and the system performance is being evaluated and will be presented in this project.
