RO membranes are thin and semi permeable layers which are used in purification of water in order to separate dissolved solids and impurities. When pressure is applied and water is passed through these membranes, it allows clean water to pass and blocks substances such as salts, bacteria and viruses. RO membranes are used in various applications such as desalination, water & wastewater treatment, and different industries for production purified water with high quality by efficiently removing unwanted contaminants.
