[0002] Reverse osmosis technology is the most advanced and effective membrane separation technology today. Its principle is to separate these substances and water under the action of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. Since the pore size of the reverse osmosis membrane is very small, it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. Reverse osmosis is currently the most widely used desalination technology in high-purity water equipment. Its separation targets are the ions in the solution and organic matter with a molecular weight of several hundred.
