The resin or mineral inside the softener tank is designed to remove “hard” particles of lime and calcium, through an ion exchange process. The resin beads inside the softener tank that dissolve particles of the incoming water. The dissolved particles suspended in your water will cling to the resin beads on contact, thereby ridding the water of these particles, causing the water exiting the unit to be “soft”. The resin has a limit to how much of these hardness particles it can hold, which is why we do a regeneration or brining of the tank.
