Hard Water softner contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe). Removal of these minerals are accomplished by softening the water through an ion exchange process using a water softener. As the water flows through the mineral tank of the water softener, the dissolved minerals become attached to the resin, creating soft water. Over a period the resin in the water softener will become exhausted, and the water softener will regenerate using a brine solution produced from the salt in the brine tank..

The Hard water softener flows over resin in the resin tank. Resin is in the form of tiny beads that have a special chemical property. At low concentration of sodium in typical hard water, the resin beads absorb (combine with them) the hardness of water and replace it with an equivalent amount of sodium in water. As hardness is removed, the water becomes "soft". The resin has a fixed capacity of the amount of hardness it can remove. Once that happens the resin can no longer remove the water hardness and the resin is called "saturated" or exhausted.
RO Water Purifier Fortunately, the same resin when exposed to high sodium chloride (common salt) concentration reverses the process, absorbs the sodium, and releases the hardness. This property is utilized in regenerating the exhausted resin. This is done by temporarily stopping the softening process and exposing the resin to high salt solution from the brine tank. The entire process is controlled by the controller valve which works either on time of regeneration (normally set at 2 AM) or by a meter valve inside the controller, preset to a calculated amount of water that can be softened before regeneration. After regeneration the controller rinses the resin to remove all salt not absorbed by the resin. The entire cycle lasts less than 1 hour.
The softening process adds a very small amount of sodium in the water, which comes from the exchange process. It is not directly added from the brine tank. For example, water with 10-grain hardness will have a sodium addition of 80 ppm in the water after softening.
