Reverse osmosis (RO) technology is an important part of membrane separation technology. Reverse osmosis is the reverse migration movement of permeation, a separation method that separates the solute in the solution from the solvent by means of selective sequestration of the semipermeable membrane under pressure. Reverse osmosis technology is widely used in the purification and concentration of various liquids. The most common application example is the use of reverse osmosis technology to remove inorganic ions, bacteria, viruses, organic matter and colloids in raw water. To obtain high quality pure water. It has the advantages of high water quality, low operating cost, no pollution, easy operation and reliable operation, and becomes the most energy-saving and simplest technology for seawater and brackish water desalination and pure water preparation.
At present, reverse osmosis technology has become the preferred water treatment technology in modern industry, and is widely used in many industries such as medicine, electronics, chemicals, food, desalination and so on.
