Dear student,
In the ion exchange process,sodium ions are used to coat an exchange mediumin the softener. The exchange medium can be natural “zeolites” or synthetic resin beads that resemble wet sand. During this process, “free” sodium ions are released into the water.
The strong acid cation exchanger resin is regenerated withsulphuric or hydrochloric acid, which effectively strips off the calcium, magnesium and sodium from the resin, substituting hydrogen. Hydrochloric acid is typically applied at between 4 and 6%.
