magnesium. While there are chemical treatments that do this, we believe that
the healthiest and best method is installation of a water
softener. A water softener is a mechanical appliance that's plumbed into your home's water supply system. Softeners trade the damaging minerals for sodium ions. The process is called ion exchange. The heart of a water softener is a mineral tank. It's filled with small
polystyrene beads, also known as resin. The beads carry a negative charge. Calcium (Ca2+) and magnesium (Mg2+) ions that cause water hardness can be removed fairly easily by using this ion exchange procedure. Water softeners are exchange devices. Exchange involves the replacement of the hardness ions with non-hardness ions. Water softeners use sodium (Na+) as the exchange ion. Sodium ions are supplied from dissolved sodium chloride salt, also called brine. In the ion exchange process, sodium ions are used to coat an exchange medium in the softener. The exchange medium is made of resin beads that resemble wet sand. As hard water passes through a softener, the calcium and magnesium trade places with sodium ions. Sodium ions are held loosely and are easily replaced by calcium and magnesium ions. During this process free sodium ions are released to the water. After softening a large quantity of hard water the exchange medium
becomes coated with calcium and magnesium ions. When this occurs, the
exchange medium must be recharged or regenerated. To recharge the sof Maintenance of water softeners is largely confined to restocking the salt supply for the brine solution. The brine tank may require periodic cleaning. The frequency of cleaning depends on the amount and purity of the salt used in the softening process. The brine valve and float assembly should also be checked and cleaned as often as needed. To learn more about water softeners, please go to these pages:

sodium ions, a softener is backflushed with a salt brine
solution. During a backflush the brine solution replaces the calcium and
magnesium ions on the exchange medium with sodium ions from the salt
solution.
