Osmosis is a natural process. In this process, water flows without energy. But to create a reverse flow, it needs to put pressure on saline water. If a semipermeable membrane is placed between two solutions of different concentrations, some of the solvents are transferred from one side of the membrane to the other.
Reverse osmosis is one of the methods widely used today in seawater desalination, separation of organic and toxic substances from industrial wastewater.

Desalination is a separation process used to reduce the dissolved salt content of saline water to a usable level. Reverse osmosis (RO) is proved to be the most reliable, cost effective, and energy efficient in producing fresh water compared to other desalination technologies.
The newest commercial technology for desalination is based on membrane treatment. Brackish Water Reverse Osmosis (BWRO), or Sea Water Reverse Osmosis (SWRO), is the fastest growing desalination technique with the greatest number of installations around the globe; it is beginning to dominate the current and future desalination markets. Its energy consumption is usually some 70% less than for comparable evaporation technologies. Advancements have been made in membrane technology, resulting in stable, long-lived membrane elements. Component parts have been improved, as well, reducing maintenance and down time. Reverse osmosis delivers product water or permeate having almost the same temperature as the raw water source. This is more desirable than the hot water produced by evaporation technologies. RO systems can be designed to deliver virtually any required product water quality. For these and other reasons, RO is usually the preferred method of desalination today.
