Commercial Water Treatment Low Pressure Reverse Osmosis RO Membrane
(2521 / 2540 / 4021)
Commercial reverse osmosis membrane elements are widely used in
electric power, petrochemical, steel, pharmaceutical, food and
beverage, municipal and environmental protection fields. It plays
an important role in seawater desalination and brackish water
desalination, boiler water supply, industrial pure water and
electronic ultrapure water equipment, drinking pure water,
wastewater treatment and special separation processes.
