What's the function of ion exchange resins for water treatment?

Answer:

The resin is divided into cationic and anionic resins in water treatment, cation resin is subdivided into sodium and hydrogen, can the dissociation of some cations in aqueous solution (such as H+ or Na+), sodium calcium and magnesium in water exchange resin for sodium ions, the water becomes soft; hydrogen type resin is calcium and magnesium in water the exchange of softening water into hydrogen ions,...
The use of mixed resin resin and cationic anionic resin can remove all anions and cations leaving only water molecule ion exchange
In the field of water treatment, the demand for ion exchange resin is very large. It accounts for about 90% of the total output of ion exchange resin, and is used for the removal of various anions and cations in water. At present, the maximum consumption of ion exchange resin is used in the pure water treatment of thermal power plants, followed by atomic energy, semiconductor, electronic industry and so on.
It can remove many kinds of ions in water, but it can not remove molecules.
