With a strong selective retention capacity for low valence anions and high valence anions and a very low operating pressure, it can be widely used in the purification and desalination of drinking water, the concentration and separation of sugars, amino acids, organic acids, etc.; the desalination or decolorization of surface water, waste leachate and printing and dyeing waste water; it can also be widely used in the fields of pharmaceutical extraction, salt chemical industry and material concentration.
