Water softeners are units that take away hardness minerals, akin to calcium and magnesium, from water. Salt-based water softeners use ion change to take away these minerals, however they will additionally add sodium to the water, which generally is a downside for individuals on low-sodium diets. Salt-free water softeners, then again, don’t use ion change, so they don’t add sodium to the water. As a substitute, they use quite a lot of different strategies to take away hardness minerals, akin to template-assisted crystallization (TAC), chelation, and magnetic or digital water conditioning.
Salt-free water softeners have gotten more and more widespread as a result of they provide an a variety of benefits over salt-based water softeners. First, they don’t add sodium to the water, which makes them a good selection for individuals on low-sodium diets. Second, they’re usually extra inexpensive than salt-based water softeners. Third, they’re simpler to keep up, as they don’t require common salt additions. Lastly, they’re extra environmentally pleasant, as they don’t produce wastewater.
