The Desalination Refers to any of several processes that remove salt and other minerals from water. Water is desalinated in order to convert salt water to fresh water so that it can be suitable for human consumption or irrigation. Most of the modern interest in desalination is focused on developing cost effective ways of providing the fresh water for human use in regions where the availability of fresh water is, or is becoming, limited. In the present work a detailed study on various processes of desalination that are currently at commissioning stage is done. The opportunities and challenges of desalination processes in general are discussed. The advantages and disadvantages of main desalination processes are reported. The cost analysis of each process is done. The cost comparison of the various processes along with their capacities has been reported. From the comparative study it can be concluded that the reverse osmosis is the most promising desalination process. This process can be made effective using carbon nanotube membranes. Carbon nanotube membranes for water desalination are described in detail.Keywords
