Reverse osmosisReverse osmosis (RO) membranes are critical components of RO systems used for water purification. These membranes utilize a semi-permeable layer to remove impurities, particles, and contaminants from water. RO membranes are highly efficient in removing dissolved solids, organic matter, and minerals, producing high-quality water suitable for various industrial and domestic applications. RO membranes are available in different materials and configurations, including spiral-wound, hollow-fiber, and flat-sheet designs, to meet various water treatment needs. RO membranes are a popular choice for water purification, and understanding their types and functions is crucial for selecting the most suitable membrane for the specific application.
