The standard whole-house softener works on the principle of ion exchange, termed "cation exchange." It conditions hard water by substituting sodium chloride (salt) or Potassium chloride for the hardness minerals such as calcium, magnesium, and iron.
Inside a cation-exchange softener, the house water supply flows through plastic-like beads called "resin," arranged in columns called "resin beds" that reside in the "resin tank." These beads attract the mineral ions of hard water while giving off sodium ions. To periodically recharge the beads with sodium ions, they're flushed with salt water (brine), a process that removes the hard mineral ions from the resin and discharges them as waste. Once excess sodium is rinsed away, the cycle begins again.
