ION EXCHANGE

Ion exchange is a physical-chemical process in which ions are swapped between a solution phase and solid resin phase. The solid resin is typically an elastic three-dimensional hydrocarbon network containing a large number of ionizable groups electrostatically bound to the resin. These groups are exchanged for ions of similar charge in solution that have a stronger exchange affinity (i.e., selectivity) for the resin. In drinking water treatment, this technology is commonly used for softening and nitrate removal.

Benefits of High Efficiency Softeners (HES) are:

• Proprietary design uses less salt, 4 Lbs/cu.ft resin
• 30-50% lower salt use, 75% lower regeration waste water
• Polished quality with minimum hardness ion leakage
• Dual units for continuous treated supply
• Preventive maintenance program
• Economical design & simple operation
• Automatic operation
