Reverse Osmosis (RO) membrane is a high-efficiency semi-permeable membrane widely used in water treatment. Made of high-quality polyamide materials, it features a dense structure that can effectively intercept most impurities under a certain pressure. It only allows water molecules to penetrate, removing dissolved salts, organic pollutants, and microorganisms without adding any chemicals. Suitable for household, industrial and marine applications, it is a vital component for obtaining clean and safe pure water.
