Water softeners modify the physical and chemical composition of water, reducing both calcium and
magnesium, which cause scaling.
The water to be softened transits through ion exchanging resins (strong cationic resins), which
change the calcium and/or magnesium into sodium.
The water delivered by the softener no longer causes scaling, and has become ‘soft’.
The purpose of the water softener is to provide maximum protection against scaling in pipes
and other equipment. As the water passes through, the resins become saturated with calcium
and magnesium.
A regeneration cycle is then necessary, to recharge the resins in sodium ions, from a sodium
chloride solution or brine (salt and water), which the softener takes from the salt box.
Regeneration is activated automatically, during the night, by an automatic system integral with
the softener head. Regeneration can be activated in 2 ways:
- based on volumes consumed (volume mode),
- based on time interval (time mode).
Industrial softeners are designed for any installation treating large volumes and flows. They can be installed on systems with one or more water points. The most frequent installations are in: hotels, industrial plants (process/general system), schools, etc, community buildings,
medical sector (hospitals, clinic, retirement homes). Softeners are installed on pipes carrying cold water that is to be heated to provide sanitary hot water, in all public or community buildings (public health laws).
