Protection of Ion Exchange Resin during Storage

Ion Exchange Resin, supplied in dry or moist condition, require proper care at all times. Always keep the resin drums/bags closed and in the shade at a temperature between 10oC and 40oC.
Most Resin: Resins which are supplied in moist condition must never be allowed to dry. Regularly open the drums/bags and check the condition of the resin. If the resin is not moist enough, add decriminalised water to keep it in completely moist condition.
Dry Resins: Resins which are supplied as dry beads or dry powders should never be allowed to come in contact with moisture.


Moist Resins: All water treatment resins and resins supplied in moist condition are generally sold on volume basis. The volume is measured in a column after back-washing, settling and draining of water to the bed surface.
Dry Resins: All dry resins are sold on weight basis.

How does the Ion Exchange Resins help in water treatment system ?

Ion exchange resins finds its application in the treatment of water. In this process, the sodium ions swap with calcium and magnesium ions to remove the hardness of the water. The process is sometimes known as dealkalization, de-ionization. Now, let’s understand how the ion exchange process helps in water treatment system.

How this process purifies water?

Ion exchange is a process in which swapping between different ions occurs of a similar charge. The magnetic properties of atoms help in removing contaminants from water. During this process, the exchange takes place between different particles. These ions form group with resin material. The transfer occurs between cation ions and anions that come in contact with each other during the water purification process. During the anion exchange process, the swapping between negative ions occurs with negative ions seen on the resin surface, generally chloride. Various water contaminants like nitrate, fluoride, and arsenic can be quickly pull off during the anion exchange process.

The resins are can help in treating water. If there is a substance known as benzene that doesn’t fall in this group, it cannot be withdrawn using the ion-exchange process.

How Ion Exchange Resin helps in treating drinking water?

The Ion Exchange process helps in the treatment of drinking water as well. Special resins are available now that allow in extracting contaminants from drinking water, including uranium and perchlorate. There are multiple resins for this purpose, like durable base resin, which removes nitrate and perchlorate, and then there are resin beads that help in water softening.

How to recharge resins?

Resin materials have a finite capacity. When the swap process doesn’t occur, the regeneration process takes place to bring back to its original condition. Various substances help in this process, like sodium chloride, hydrochloric acid, sodium hydroxide, and sulfuric acid.

This process is highly beneficial and finds its application in industrial use and to treat municipal wastewater. The process’s efficiency depends upon mineral scaling, surface clogging, and other issues that help in resin fouling. Pretreatment processes like filtration or the addition of chemicals help in the prevention of such problems.

The capacity of water treatment depends upon the type of exchange material, amount of dissolved material, regeneration process, and mechanical condition. The process is simple and helps to remove harmful minerals from water.
