Summary of Reverse Osmosis and Application Fields

Summary of Reverse Osmosis

Reverse osmosis technology is a modern high technology developed recently in China. Reverse osmosis is to separate water from solution after it permeates the specially-made semi-transparent membrane through exerting a pressure that is higher than the osmosis pressure on the solution. As this process is reverse to the natural permeation direction, it is called reverse osmosis. According to different osmosis pressures of various materials, the process of reverse osmosis with a pressure higher than the osmosis pressure can be used to reach the purposes of separation, extraction, purification and concentration of a certain solution. It does not need heating and there is no phase changing process; therefore, it saves more energy than traditional process.
