| ion exchange |
Ion (anion or cation) exchange systems soften hard water by removing the minerals (calcium and magnesium) that cause hardness. Ion exchange units also remove iron, manganese and many heavy metals. The hard water is pumped through a tank containing an exchange resin. Sodium on the resin replaces the hardness minerals. The sodium remains in a soluble form in the softened water.

| ion exchange chromatography |
In this case, water is passed through a charged resin column that has side chains that trap calcium, magnesium, and other heavy metal ions. In many laboratories, this method of purification has replaced distillation, as it provides a high volume of very pure water more quickly and with less energy use than other processes. Water purified in this way is called deionized water.
