Resin Analysis

Res-Kem Corp offers independent resin analysis to help determine if and when to replace the resin. Our in-house engineering staff can assist in reevaluation of your resin choice in the event the conditions of operation have changed. Res-Kem Corp has the knowledge to determine what type of resin will work best to maximize the output of your equipment

Resin Equivalency

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:

1. Strong acid cation (SAC)
2. Weak acid cation (WAC)
3. Strong base anion (SBA)
4. 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:

1. Nitrates
2. Organics
3. Arsenic
4. Perchlorate
5. 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.
