Ion Exchange

ION EXCHANGE

Ion exchange is an exchange of ions between two electrolytes. The term is often used to describe the process of purification, separation and decontamination of aqueous and other ion-containing solutions. Ion exchange can also be used to remove hardness from water by exchanging calcium and magnesium ions for sodium ions in an ion exchange column.

Nalco Pretreatment Solutions (PTS) designs and manufactures water treatment equipment, many of which use ion exchange resins to treat the water. 

The two primary ion exchange resins used in our equipment are strong acid cation ion exchange and strong base anion ion exchange resins. 

In our service DI tanks, we mostly use mixtures of cation resins regenerated using a concentrated acid solution, and anion resins regenerated using a concentrated caustic solution termed a mixed bed.  Softeners and condensate polishers use cation ion exchange resins and regenerate using a concentrated sodium chloride (brine) solution. Dealkalizers use anion resins and regenerate using a brine solution as well.

Nalco PTS manufactures Resin Traps for 2", 3" and 4" piping to prevent resin and other media from contaminating downstream equipment.

Nalco PTS also offers Ion Exchange resin testing analysis services as well as onsite preventive maintenance to monitor and maintain these units in peak performance and reduce the workload of your team.
