RO is a technique of separating solutes from solvents of the same solution by means of selection and interception by the semi-permeable membranes, when driven by pressure.Use of reverse osmosis technology can effectively remove dissolved salts, colloids, bacteria, viruses, bacterial toxins and most organic matter and other impurities, desalination rate is generally 98% or more. RO reverse osmosis equipment has the advantages of energy saving, environmental protection, continuous and stable operation of the process, small size, simple operation, strong adaptability.
