VAS softeners are designed and used to chemically transform hard water into soft
water. The treatment process is via the ‘ion-exchange’ method, whereby the hard water flows over
the resin media in the pressure vessel. The elements responsible for hardness, calcium and
magnesium ions present in the water are bound reversibly to the ion exchange resin and in return,
sodium ions are released into the water. The accumulation of calcium and magnesium ions
(hardness) on the resin is periodically removed by a regeneration process using sodium chloride
(common salt) solution or brine.
