Dealkalization

ResinTech provides several types of resins for dealkalization including strong base anion resins such as SBG1 and SBG2, weak acid cation resins, such as WACG and WACMP and strong acid cation resins, such as CG8-H.

Dealkalization by anion exchange resins is accomplished by the exchange of chloride for bicarbonate and carbonate alkalinity, thus the finished water is enriched with chlorides. Exhausted resin is regenerated with sodium chloride, much like a water softener. Although any strong base anion resin can be used, SBG2 is most commonly chosen because it has slightly higher capacity and less tendency to smell fishy.

Dealkalization by weak and strong cation resins is accomplished by exchange of hydrogen ion for hardness ions (and sodium ion in the case of a hydrogen form strong cation resin). Hydrogen ion combines with alkalinity to form carbon dioxide which is removed by degasification in a second treatment step.

All ResinTech products used for dealkalization are available in pre regenerated, ready to use forms. They are available with the WQA Gold Seal, certified to the ANSI/NSF 61 Standard and will be provided with batch certification upon request. ResinTech resins can be provided in a variety of packaging sizes and types and can be preloaded into tanks for fastest possible system implementation.
