A huge variation exists among countries in terms of freshwater availability. Water scarcity is considered a global problem that continues to grow with the fast increase in population and depleting sources of freshwater. Water desalination can be a professional solution for addressing such scarcity of water supply, but the selection of the suitable desalination method can be hard in some cases and depends on several criteria. Multi-criteria decision-making methods could be used to simplify the decision-making problem. In this paper, the preference selection index (PSI) will be used to rank seven desalination technologies; these include reverse osmosis, electrodialysis, multiflash desalination, multi-effect desalination, mechanical vapor compression, nanofiltration and ion exchange. Twelve criteria were used in evaluating the desalination methods, including the capital cost, operating cost, the energy required, recovery ratio, product water quality, adaptability, lifetime, environmental impact, simplicity, reliability, maturity and applicability. The results of the PSI model showed that the ion exchange technology is the optimal desalination technology, followed by nanofiltration technology. [ABSTRACT FROM AUTHOR]
