The future of seawater desalination: energy, technology, and the environment menachem elimelech and william a phillip content.
The process evades the problems confronting current desalination methods by eliminating the need for a membrane and by separating salt from water at a microscale the availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human. Desalination of seawater project paper the main concept of this desalination process is reverse osmosis, but we will get into that later right now what is probably running through your head is what exactly is desalination. Desalination of seawater has been commonly used to through the expanded use of desalination and water there are three basic approaches to separating water. The water fed into a desalination system can be seawater methods for separating reverse osmosis desalination uses high pressure to force water through.
