SOFTENING FOR DOMESTIC AND TECHNOLOGICAL USE

The mineralization of the water is due to its underground path. The chemical composition of the water changes depending on the type of rocks crossed. Calcium and magnesium are two elements commonly present in the composition of natural waters and are responsible for the "hardness" of water. This term indicates the property of (hard) water to deposit calcareous encrustations in heat exchange devices and in general in plumbing systems, including household appliances.

The damage caused by hardness manifests itself particularly clearly where heat exchange processes occur which lead to heating of the water. Above 50°C, in fact, the calcium and magnesium salts present in the form of soluble bicarbonates are transformed into insoluble carbonates capable of precipitating, forming encrustations.

When the water is hard it is a good idea to carry out a softening treatment. The hardness value at which softening is essential depends on the type of application. In the case of hydro-thermal-sanitary systems, the UNI 8065 standard establishes that softening is mandatory for hardnesses above 15 °f (for systems with a thermal power of the hearth > 100 kW).

Regardless of the heat output of the hearth, softening treatment is still recommended if the hardness of the water exceeds 15°f.

When choosing the water softener, the fundamental hydraulic parameters that determine the choice are:

- Instantaneous flow rate: it is the maximum flow rate that can pass through the softener for which the exchange process is still guaranteed. If the softener is fed with a higher flow rate, the speed at which it crosses the bed is so high as to cause inevitable hardness leaks.

- Cyclic capacity: it is measured in m3x°f and represents the exchange capacity of the softener. This data is of fundamental importance in order to establish the interval between two subsequent regenerations.

Water softeners exist in two versions:

- Cabin or monobloc: they are the ideal solution for domestic applications as they are small in size. They are ideal for applications where low flow rates or limited cyclic flow rates are required.

- Double body: the tank and the column are two separate entities and constitute the ideal solution for applications where high peak flow rates or cyclic flow rates are required.
