Cation Exchange Water Treatment Systems

Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange resin more precisely the term encompasses a large variety of processes where ions are exchanged between two electrolytes.

Cation exchange water treatment systems. Ion exchange is the reversible interchange of ions between a solid ion exchange material and a liquid in which there is no permanent change in the structure of the solid. Common cations include ca 2 mg 2 fe 2 and h 1. Ion exchange is used in water treatment and also provides a method of separation in many non water processes. Ion exchange is a water treatment process commonly used for water softening or demineralization but it also is used to remove other substances from the water in processes such as dealkalization deionization and disinfection.

In this process it is important that both positively and negatively charged ions are removed. So3 so3 so3 so3 so3 so3 so3. Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge. But what exactly is it.

Cation anion ion exchangers are used to produce demineralised water. Polymeric skeleton of the resin bead. The fixed ions of this cation exchange resin are sulphonates so3 that are attached to the skeleton. Therefore a treatment in 2 steps is required.

In this picture the mobile ions are sodium na cations. A cation resin is one that exchanges positive ions. Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes. It is porous and contains water.

While the chemistry of individual ion exchange reactions varies from one application to the next ix is a treatment process where dissolved ions are replaced by other more desirable ions of a similar electrical charge. There are two general types of ion exchange resins. Northeast regional agricultural engineering service cooperative extension. Aside from its use to purify drinking water the technique is widely applied for purification and separation of a variety of industrially and medicinally.

Our systems are also efficient in reducing toxic metals radium reduction unwanted color perchlorates and dbp precursor. See questions to ask before you buy a water treatment system for more information. Before installing an anion exchange unit consider the requirements of the treatment system. First the ion rich water will flow into the cationresin column.

This will help you determine if cation exchange is an effective treatment method for your situation. Nitrate and sulfate are odorless colorless and non staining so only drinking and cooking water may require treatment. Those that exchange positive ions called cation exchange resins and those that exchange negative ions called anion exchange resins. A cation is an ion with a positive charge.
