Precise way to select a desalination technology

The limited natural water resources in the world pressures the scientist and engineers to develop alternative sources which are brackish/seawater desalination. Seawater desalination process selection is a critical decision based on geographical location, energy costs and availability as well as operator skills. A decision maker requires much updated information related to desalination technologies to put huge investment in the right place. The present paper will describe the popular desalination processes being used nowadays in the world and their latest developments, advantages and challenges to compete each other to produce reliable and cheapest potable water. This paper will indicate ideas to improve a technology. MARAFIQ with its existing facilities and future projects will significantly contribute in this field. The paper also will explore the desalination processes in MARAFIQ and 800,000 m3/d future promising IWPP.
