Ion Exchange Resin

Listing ID #1360507

We are among the prime manufacturers and suppliers of Ion Exchange Resin. Ion Exchange Resin removes unwanted ions from a raw water by transferring them to a solid material, called an Ion Exchange Resin, which accepts them while giving back an equivalent number of a desirable species stored on the Ion Exchange Resin skeleton.
The Ion Exchange Resin has a limited capacity for storage of ions on its skeleton, called its exchange capacity; because of this, the Ion Exchange Resin eventually becomes depleted of its desirable ions and saturated with unwanted ions. It is then washed with a strong regenerating solution containing the desirable species of ions, and these then replace the accumulated undesirable ions, returning the exchange material to a usable condition. This operation is a cyclic chemical process, and the complete cycle usually includes backwashing, regeneration, rinsing, and service.
Polystyrene-divinylbenzene resins are still used in the majority of Ion Exchange Resin applications. Although the basic resin components are the same, the resins have been modified in many ways to meet the requirements of specific applications and provide a longer resin life. One of the most significant changes has been the development of the macroreticular, or macroporous, resin structure.
Ionizable groups attached to the resin bead determine the functional capability of the resin. Industrial water treatment resins are classified into four basic categories :

• Strong Acid Cation (SAC)
• Weak Acid Cation (WAC)
• Strong Base Anion (SBA)
• Weak Base Anion (WBA)
