RECYCLING OF THE EXHAUSTED CATION EXCHANGE RESIN FOR
tercurrent regeneration technology to your ion exchange system without the problems associ-ated with other countercurrent technologies. In the following pages, we’ll profile our resin products for you. But first here’s a brief overview of the polymer structures we use to produce resins for the broad spectrum of ion exchange applications. Capacity, Stability, and Strength Most DOWEX resins metro map download in pdf The regeneration of cation and anion exchange resins used in deionizers is a more complicated process than simple softening. The process includes the use of strong acid and caustic. It is important to observe the appropriate safety considerations for handling these chemicals and …

Valence is the term that describes the category of the electrical charge on a dissolved ion such as positive 2 or positive 3. If the contaminant has a positive charge, it would be called a cation, and would be removed by use of an IE media called a cation exchange resin. If the contaminant has a negative charge, it
