How Do Salts Soften Hard Water?

Hard water is water that contains calcium and magnesium minerals which make it unsafe to drink, difficult to use for washing and bathing, and expensive to use. Hard water is responsible for scale formation and clogging of electric showers or drainage systems. Constant use can damage your bathroom appliances and affect your health.

Salts are vital in the softening process of hard water due to the presence of sodium. It is the sodium in salt that interchanges hard water minerals such as calcium and magnesium and converts it to soft water which is safe for use. During the water softening process the sodium ions in the resin beads attract hard water minerals riding the water of calcium and magnesium.

Salts present in the brine solution or brine tanks also aids the regeneration process in water softeners. After constant conversion of hard water to soft water, the resin beads present in the softener becomes coated with residues of calcium and magnesium ions which reduces the efficiency of the device. When this happens, a salt solution or brine solution as it is commonly known is passed through the resin beads to flush away all magnesium and calcium ion build up.

Are salt-free systems effective?

Salt-free systems such as scale inhibitors, magnetic softeners, and electrolytic softeners are a cheaper but ineffective alternative when it comes to water softening.

In most cases, these systems only get rid of scale build up in your plumbing system but don’t change the water composition; in other words, they don’t remove the hardness.

They might seem like a cheaper option, but according to numerous studies and customer reviews, salt-free systems don’t convert hard water to soft water.

It is recommended that you purchase an ion exchanger water softener that uses salt to soften hard water.
