Description

Water softening literally means you are removing the hardness causing minerals (mainly calcium and magnesium) from the water through a process called ion exchange. Salt-based water softeners contain a resin bed which filters the water through, exchanging those hardness minerals for sodium particles.Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. … Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or ion-exchange resins.
