Softeners utilise ion exchange resin beads to remove the hardness causing calcium (Ca2+) and magnesium (Mg2+) ions from water in a reversible process. The resin beads are polystyrene spheres approximately 1 mm in diameter and have numerous charged sites on the surface that initially hold sodium (Na+) ions. During operation, the ion exchange resin beads will release the Na+ ions and in their place will attract the Ca2+ or Mg2+ ions. The water that leaves the softener system will have the hardness removed but with an increase in Na+ ions. After a certain volume of water has been treated, all of the Na+ ions will have been exchanged from the resin to the water and the resin will require regeneration. 


The regeneration process introduces a concentrated brine solution (Na+ & Cl-) to the resin beads which forces off the hardening ions and returns Na+ ions to the ion exchange resin. The resin is then ready to return to service and start the next production cycle. 


Softeners use multi-valve manifolds and control logic to automatically initiate regeneration cycles based on time in service or the volume of water treated.
