In the production of ionic membrane caustic soda, the presence of sulfate ions destroys the ion exchange membrane, so the concentration of sulfate ions in the brine is strictly controlled.
The anion exchange method is a method in which sulfate ions are adsorbed by a resin when the brine flows through the ion exchange resin according to the selective permeability of the ion exchange resin.
Suzhou Bojie Resin Technology Co., Ltd. provides sulfate removal resin, which is easy to operate, low in environmental requirements, and easy to regenerate. It is widely used in the removal of sulfate ions in brine in the chlor-alkali industry.
