With Rielli water softening units, the calcium and magnesium ions, known as lime among the people, imparting hardness to the water are picked up from the water and thus the water is softened. Under the current environmental conditions where water quality is getting worse every day, you may protect all your water installation against lime by using softened water and thus extend service life of your dishwashers and reduce power consumption for water heating considerably. Benefits from use of softened water are not limited to them; the laundry washed in soft water gets whiter and the colors more vivid. No lime stains appear on the dishes. Consumption of cleaning materials reduces considerably.
As to the industrial applications, use of water conditioned correctly will extend service life of your heating units, providing efficiency and quality improvement with respect to washing and dyeing operations.

Water softening units operate by a process different than filtration. Basic principle of the softening process is ion exchange. Essential ions imparting hardness to the water are Ca and MG ions. For ion-exchange process, sodium-based cationic (acidic) resin is used. During service, the resin collects on it Ca and Mg ions having +2 value in the water. At time of regeneration, Na ion is given to the unit. As Na ion can be reinforced by NaCI component in the easiest and cost-effective way, saline water is used for this purpose. While the resin retains Na ion, it releases Ca and Mg ions. Ions imparting hardness to the water are thus drained. Thus the unit becomes ready for the following service upon regeneration of the resin.
As it may be understood, the most important parameters affecting efficiency of the equipment are quantity of resin and chemical formula of the resin. Surface speed remains as secondary parameter.
