Sitting water is nothing more than eliminating calcium and magnesium salts from its composition. In everyday life, it is precisely because of these substances that there is an overgrown of the internal surfaces of boiler units, water pipes, plumbing and various household equipment in contact with water. Not a very pleasant sensation remains after the adoption of baths. If you use water with excessive rigidity for the manufacture of alcohol and non -alcoholic drinks, cooking, etc.D., then the negative impact on the taste of the finished product cannot be avoided.
It is justified by the World Health Organization is regulated by the content of hardness salts in drinking water: 1.0 – 2.0, and for food – in the range of 0.1 – 0.2 m -EKV/l.
If we talk about heating systems, then even a meager amount of rigidity salts will cause a decrease in heat transfer, and as a result of increasing fuel costs. Therefore, the content of calcium and magnesium salts in the energy system is limited by 0.03 – 0.05 m -EKV/l.
The main methods of softening water at home
Today, the most famous options for removing hardness salts from water are considered:
Reagent method.
Ion exchange.
Nanofiltration.
Reagent method
Hardness salts are characterized by poor solubility. To increase it, additional substances are used, reagents. It can be soda or slaughter lime. Here, in addition to reagents, it is also necessary that the presence of clarifiers, containers, as well as high temperatures. This method of softening water is rarely used, since as a result the liquid has an alkaline flavor.
Water mitigation using ion exchange systems
The principle of operation of such systems is very simple: salts dissolved in water react with loading, which is presented in the form of ion exchange resin. One such load is enough for several years of use.
Nanofiltration to soften water
Passing water through the nanofiltration membrane, it is possible to eliminate almost all suspended particles, colloids, heavy metals and even organic impurities. With the help of such devices, you can reduce the concentration of hardness of stiffness by more than 20 times. If you want to achieve maximum efficiency, you can use the backsmos systems that today occupy a leading position among all filters.
