Design and installation are essential for the efficiency of a water treatment plant. As we can see in the article on Primary Water Treatment, they are not only used for water supply, they improve processes by reducing chemical elements, they give durability to devices with low maintenance and they acquire the necessary parameters to be consumed.

Demineralization Treatment depends of the volume and quality of the water to be treated. The reverse osmosis process (see Secondary and Tertiary Water Treatment) or an ion exchange resin demineralizer is recommended to soften the water or remove mineral content. This process of removing mineral salts from Water by using the ion exchange process it’s important because the resin with sodium cations that is exchanged for magnesium and calcium. Calrification is important to prevent scaling in the equipment, because precisely the hardness of the water causes scaling problems in installations, machinery and quality failures in final processes.
Let’s see the following situation: “When the resin has exchanged a large number of calcium and magnesium ions, it is no longer possible to decalcify any more water, because the bed is saturated and it is necessary to carry out a regeneration that allows the initial capacity of the resin to be recovered. For regeneration, a concentrated solution of common salt (brine) is required, which consists of reverse exchange. This causes the elimination of calcium and magnesium ions, along with the saline water to the drain. And sodium ions are installed in their locations to return to the decalcification process”.
