A system or equipment called a water softener is used to remove minerals from water, typically calcium and magnesium ions. We refer to the process of eliminating these minerals as "water softening." In regions where the water supply is regarded as "hard," or has significant amounts of calcium and magnesium ions, water softeners are frequently utilized. Beads of resin coated in sodium ions are found in the water softener. A system or equipment called a water softener is used to remove minerals from water, typically calcium and magnesium ions.
