Strong base anion resins derive their functionality from quaternary ammonium exchange sites. The two main groups of strong base anion resins are Type 1 and Type 2, depending on the type of amine that is used during the chemical activation process.

Type 1 resins are suitable for the total elimination of anions in all waters, they must be used in waters with high alkalinity and high silicon content.

Type 2 resins also exhibit removal of all anions, but may be less effective at removing silicon and carbon dioxide from waters where these weak acids constitute more than 30% of total anions. These types of resins are frequently used in water softeners or softeners.

They are used in de-ionization columns in demineralizers. Removes anions from water and requires a large amount of regenerant, commonly soda (sodium hydroxide - NaOH)

Weak base anion resins contain the polyamine functional group, which acts as an acid absorber, removing strong acids from the cation effluent stream. These resins should be used in waters with high levels of sulfates or chlorides, or where the elimination of alkalinity and silicon is required.

The weak base anion resin is very efficient, it requires less soda NaOH for its regeneration. It cannot be used at high pH and can suffer from oxidation or fouling problems.
