Morton System Saver Water Softeners Work
The most common water softening
method called "ion exchange," is a reversible chemical
process of exchanging hard water ions for soft water ions.
Calcium and magnesium are the hardness ions, sodium can be
considered the "softness" ions and they are exchanged
to create soft water.
Ion exchange takes place in
a "resin bed" made up of tiny bead-like material
often made of styrene and divynlbenzene. The beads, having
a negative charge, attract and hold positively charged ions
such as sodium, but will exchange them whenever the beads
encounter another positively charged ion, such as calcium
or magnesium minerals. This ion exchange happens very easily
since the sodium ions have a positive charge of only one,
while magnesium and calcium have a more powerful positive
charge of two. A further explanation is available in the
Cycle Information Chart.
