Overview
Reverse osmosis (RO) technology is an energy-saving and efficient membrane separation technology. Its principle is to separate solutes and solvents in a solution by using the selective retention effect of a reverse osmosis membrane that only allows water molecules to pass through, under the action of a pressure higher than the osmotic pressure of the solution, in order to achieve the purpose of separation and purification. It has been widely used in the purification and concentration of various liquids, with a common application example being the use of reverse osmosis technology in water treatment processes to remove impurities such as inorganic ions, bacteria, viruses, organic matter, and colloids from raw water, in order to obtain high-quality purified water.
