RO
Acid-resistant high-pressure reverse osmosis membrane elements are suitable for the desalination of highly acidic and saline wastewater with a salt concentration of 5000mg/L or more. Through customised optimisation of the membrane process, the membrane elements are characterised by high acid resistance, high desalination, high stability and cleaning recovery, and can be widely used for the deep concentration treatment of acidic wastewater.
