Web27 apr. 2024 · In anion exchange treatment, water passes through a bed of synthetic resin. Nitrate ions in the water are exchanged with ions, typically chloride, that are preloaded onto the resin. When the capacity of the resin is exhausted, it is regenerated to restore it to its initial condition using a solution of sodium chloride (also known as brine). WebWorking principle of ion exchange water treatment system. The device apply strong acid cation resin to replace calcium and magnesium ions in raw water, and then the water after treatment of softening and desalting can be directly used as the make-up water of steam boiler. The chemical reaction is as follows: 2RNa+Ca2+ (Mg2)=R2Ca (Mg)+2Na+.
