Demineralization is a process that consists in the removal of all dissolved mineral salts from water, so that a good heat transmission is achieved. It is also possible to avoid the deposit of incrustations and the corrosion or deterioration of the surfaces in contact with water. The most common pattern is cationic and anionic resin columns connected in series.
Water passes through the cationic exchanger where cations of calcium, magnesium, and sodium are exchanged with hydrogen ions.
In the anionic exchanger the chloride, sulfate, bicarbonate ions are exchanged with hydroxide ions. The hydrogen ions produced during the first phase react with the hydroxide ions and create water.
The regeneration of resins occurs when they are exhausted. Regeneration is automatically or manually created by means of a solution of hydrochloric or sulfuric acid in cationic exchangers and caustic soda in anionic exchangers.
