How ion exchange resin works in a water softener

- Apr 17, 2019-

The exchange takes place by passing hard water over man-made ion exchange resin beads, in a suitable pressure vessel tank. The resin in most modern softeners (polystyrene divinyl benzene) consists of millions of tiny plastic beads, all of which are negatively charged exchange sites. The ions considered in this process (calcium, magnesium and sodium) are all positivly charged ions.

When the resin is in the base state, the negatively charged resin beads hold positively charged sodium ions. As the calcium and magnesium contact the resin beads in their travel through the resin tank, they displace the sodium ions from the exchange sites.
