How does an ion exchange water softener work?
It is known that only the ion exchange process truly softens water, by extracting the minerals that cause lime-scale from hard water. But how does that work exactly? Find out below!
The ion exchange process involves the exchange of the hardness minerals in water, chiefly calcium and magnesium, for sodium minerals. The exchange is made possible because the minerals are ionic in nature, which means they have an electrical charge. The ion exchange process is based on the fact that like charges repel one another and opposite charges attract.
An ion exchange water softener exchanges the hardness minerals (calcium and magnesium) dissolved in water for sodium. This soft mineral is contained on the softener resin beads and does not build up on surfaces as scale deposits.
