Ion Exchange Softeners and Dealkalizers – Water Technology .

May 15, 2017· Frequently, a sodium cation softener is combined with a chloride-anion dealkalizer to produce a final product water that is softened and dealkalized. The total dissolved solids have not been reduced by this method, but the softened, dealkalized water is suitable for use as makeup in many boiler feedwater applications.

Aug 07, 2008· While the heated water is beneficial for boiler feedwater, it is not good for regeneration of the anion resins. This water can approach and possibly exceed 130 degrees F. The Type II strong base anion resin temperature limit is stated by manufacturers at 105 degrees F, however, it is more prudent to maintain the limit to a maximum of 95 degrees F.

A strongly acidic cation exchanger exchanges all ca tions present in water against H + ions during regeneration with HCl and H 2 SO 4 or against Na + ions in the regeneration with NaCl. In the latter case the exchanger is called softener and is applied for instance for the treatment of service water or boiler feed water.

The advantage of a cation-anion exchanger is that it provides a very good quality of demineralised water. In addition, relatively little waste water is released. The disadvantage is that the system cannot produce demineralised water during regeneration. Such a regeneration takes several hours, depending on the resin volume.
