Water Softeners

Water Softener

A water softener reduces the calcium, magnesium and to some degree manganese and ferrous iron ion concentration in hard water
The water to be treated passes through a bed of the resin. Negatively-charged resins absorb and bind metal ions, which are positively charged
The resins initially contain univalent hydrogen, sodium or potassium ions, which exchange with divalent calcium and magnesium ions in the water
This exchange eliminates precipitation and soap scum formation
