Ion exchange resin cation can be strong acid/strong cation (SAC) and weak aced/weak cation (WAC) resins. They are suitable for several water processes:
Hardness removal — SAC removes hardness ions to soften water. SAC resin beads reduce hardness levels and increase sodium levels by removing scale-forming calcium (Ca2+) and magnesium (Mg2+) ions.
Softening and dealkalization — With WAC, hardness, alkalinity and some total dissolved solids at the same time. WAC resin usually removes about 80 percent of temporary hardness. Water treated with WAC will be acidic because WAC resin exchanges hardness and alkalinity ions for hydrogen ions.
