Soften means remove the water hardness due to salts of
calcium and magnesium, exchanging them with Sodium
salts, which do not falling and do not encrusting. To
obtain the exchange the water is passed through a bed
of resins, previously loaded with sodium, using as
tonic the sodium chloride (common table salt).
Culligan, STA’s technology partner, uses specific
exchange resins, suitable for contact with food
products, which are characterized by high wear
resistance, long life, high exchange capacity and low
power consumption of salt. For the regeneration it can
also be used the Potassium chloride.
