Automatic valve Water Softener System Water Desalination Machine Use With

Characteristics of wells containing calcium and magnesium exceeding the standard:

1. The well water after boiling has a white scale deposit.

2. Test results with hardness tester exceeded

The hardness of water is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. When

the raw water containing hardness passes through the resin layer of the exchanger, the calcium and

magnesium ions in the water are adsorbed by the resin, and sodium ions are released at the same time,

so that the water flowing out of the exchanger is the softened water from which the hardness ions are

removed, and when the resin adsorbs calcium, After the magnesium ion reaches a certain saturation, the

hardness of the effluent increases. At this time, the water softener automatically performs the

regeneration of the spent resin according to a predetermined procedure, and uses a higher concentration

of sodium chloride solution (saline) to pass the resin to make the failure. The resin is returned to the

sodium type resin.
