Chelating Resin Series For Membrane Caustic Soda



To improve the efficiency and enhance the life cycle of membranes, it is essential to supply with high purity secondary brine water for the membrane processing, which leads to the essential use of chelating resin for removing ions like Ca2+,Mg2+,Sr 2+ etc.

Since year 2009,Sunresin SEPLITE® chelating type of ion exchange resin for secondary brine purification has been topped the market share in China chlor-alkali industry,while China also has the biggest caustic producing capacity in world.

SEPLITE® LSC750 amino phosphoric acid and LSC710 iminodiacetate resin are able to effectively remove harmful ions as stated above,therefore making secondary brine water fully satisfied for membrane technique.



SEPLITE® Chelating resin for membrane caustic soda
