The necessity for fresh water is at the top of the international schema of serious issues. As the fresh water shortage becomes an issue, the application of desalination plants is rapidly rising on a large scale. Also, membrane technologies are gaining high importance for their great performance and their economic viability. Membrane distillation as a novel thermally-driven separation process can be adapted for water desalination, due to its simplicity and ability to couple with a sustainable source of energy. In this paper, study was conducted to develop a Sustainable Water Desalination (SWD) system by combining direct contact membrane distillation with solar ponds. A brief explanation of the solar pond concept and the concept of the membrane distillation (MD) system was illustrated. Additionally, the possibility of desalinating high saline water with zero brine discharge was investigated. Moreover, an alternative …
