Occasionally still referred to as Zeolite or Zeolite mineral, ion exchange
resin is functionalized polymer/plastic beads that chemically react with ions in
water. It was developed as an alternative to zeolite and functions similarly.
Regardless of brand, the core principles of ion exhange resin remain the
same. There are 4 main types of resin, each with their own function:
- Strong acid cation (SAC)
- Weak acid cation (WAC)
- Strong base anion (SBA)
- Weak base anion (WBA)
Mixed Bed resins, sometimes referred to as mix bed resin, are a combination
of cation and anion resins. Usually the ratio for mixed bed resin is 1:1 or 1:2
depending on the application. There are also specialty resins for the removal
of:
- Nitrates
- Organics
- Arsenic
- Perchlorate
- TOC
Expected Life of Ion Exchange Resins
Each application requires a different water quality. In general cation resin
for water softening and demineralization may last 5 to 10 years. Anion resins
used in demineralization last anywhere from 3 to 5 years and are dependent on
operational conditions. Like every other resin, the life of mixed bed resin is
dependent on the application in which it is being used. Resin life is
difficult to predict; in critical applications it’s best to start analyzing and
benchmarking the resin at least once per year.
