Water hardness is based off the concentration of hard minerals, such as calcium and magnesium, in water. “Soft water” has very low concentration of hard minerals, while “very hard water” has a relatively high concentration of hard minerals. Using hard water can cause mineral buildup inside of your water-using appliances which can lead to long term damage. Water softening systems “soften” the hard water by removing mineral ions through a process named ion exchange. This process consists of exchanging positively charged mineral ions in the hard water with positively charged ions, leaving the softened water free of mineral ions. There are two tanks in a water softener system that facilitate this ion exchange, the resin tank and the brine tank. The resin tank does the bulk of the water softening as the sodium ions exchange places with the mineral ions. The water exiting the resin tank contains a very small number of sodium ions, but no longer contains high levels of hard mineral ions. The brine tank then recharges the resin tank through a flushing process where the resin tank is rinsed with salt water from the brine tank. The salt water saturates the resin bead, removing any stuck mineral ion and replacing them with a sodium ion. The dissolved minerals are then flushed and the system is ready to soften water again.
