Abstract

In today’s world water scarcity is a curse for humanity which can even be leading us to extension in future. Desalination is one of the solutions to nullify this problem up to some extent which is now-a-days a growing trend. Desalination professionally was implemented in the 1960’s with its first official plant in Freeport, Texas. Since then, much advancement was made in desalination. According to the recent market condition reverse osmosis is the known process for desalination. But lately, pervaporation has also grabbed attention owning to its characteristics of removal not only salt but also metal ions. Majorly, reverse osmosis employs cellulose acetate and polyvinylidene fluoride for membrane material. The gulf countries top the desalination market with 55% of global water desalination plants in world. Currently, the dependent world population for daily needs on desalinated water is 0.1%. Countries like Saudi Arabia, Kuwait, Iraq uses 100% desalinated water for their daily needs. As there are advantages there are some flaws too like hot brine management is the biggest problem faced by desalination today.
