reverse osmosis membrane

 RO membrane generally refers to semi-permeable membrane with a pore size of less than 1 nm. It has high selectivity and permeability and can filter out suspended solids, colloids, bacteria, viruses, dissolved salts, and other impurities contained in water so that the water does not contain substances other than water molecules, and meets pure water standards. It is widely used in power, petrochemical, iron and steel, electronics, pharmaceutical, food and beverage, municipal, and environmental protection fields.
