Project Overview:

Membrane Distillation (MD) has emerged lately as promising technology for desalination. As oppose to alternative technologies, MD can operate at low temperature and pressure while maintaining 100% rejection rate. Additionally, MD is less sensitive to feed concentration which increase distilled water yield of desalination process. Consequently, MD has been proposed to utilize waste low grade heat or renewable solar energy for desalination processes. However, one major drawback of MD is the high energy consumption despite the continuous effort to optimize the processes through various configurations. We are presently evaluating a novel configuration to reduce energy consumption of MD while maintaining state of art mass flux rate through membranes. Localizing heat generation at the liquid-membrane interface reduces ambient exposure of heated mass resulting in reduction of ambient thermal losses. Additionally, operating on stagnant feed eliminates energy required for circulating fluid.
