The Water Softening Process

Hard water contains high levels of dissolved minerals, typically
in the form of calcium and iron salts. Water softening reduces
the hardness of water using an ion-exchange process. Hard
water enters the softener, passing through the ion-exchange
media where the minerals are removed by attaching to the
resin media. The softened water then flows out to the point-of­use. As the minerals build up on the media, the softening abil­ity of the media gradually reduces until the softener switches
to the regeneration cycle that removes the minerals from the
media. Brine (salt solution) is circulated through the media and
is released to drain, carrying away the hardness minerals. The
softener then returns to normal operation, resuming the soften­ing process.
