Puritreat cws Automatic Water Softeners

Automatic water softeners to remove hardness and prevent scale deposits

A range of automatic water softeners to remove hardness and prevent the formation of scale deposits. Feedwater enters the unit and passes through the ion exchange resin, which causes the replacement of calcium and magnesium ions with sodium ions to give softened water. Periodically, the exchanged calcium and magnesium is removed from the resin by regeneration using salt solution supplied from the brine tank. The regeneration process is fully automatic.
