Ion Resin Exchange Water Treatment

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.

Ion resin exchange water treatment.

While many of us have heard of ion exchange ix resins few of us have a grasp on how the technology actually works. Ion exchange ix is the reversible interchange of ions between a solid and a liquid such as water. This structure gives the ion exchange resin bead certain physical properties. As water flows through the resin bed the ion exchange process is repeated many times polishing the water to a very high purity.

Physically ion exchange resins are formed in the shape of very small beads called resin beads with an average diameter of about 0 5 millimeters. Resin beads used in ion exchange water treatment. Ion exchange resins remove harmful contaminants from liquids replacing them with beneficial desired ions. During regeneration the resin is separated into distinct cation and anion fractions as shown in figure 8 12.

The hardness ions ca and mg move into the resin beads and each of these divalent. The majority of resins in use today have a styrene divinylbenzene copolymer bead structure. Customers can send their ix resin in tanks super sacks or totes to us for regeneration. Ion exchange resins are widely used in different separation purification and decontamination processes the most common examples are water softening and water purification in many cases ion exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites also ion exchange resins are highly effective in the biodiesel filtration process.

Effective ion exchange for challenging water treatment needs. Whether you re weighing potential treatment strategies looking for ways to get the most out of your existing ix resins or simply curious about ix chemistry you may be asking what is ion exchange resin and how does it work. Ion exchange india limited pioneered water treatment in india today we are the country s premier company in water environment management with a strong global presence. Two bed demineralizers have two vessels the first containing cation resin followed by a separate vessel containing anion resin.

Modern synthetic ion exchange resins that are now used in water treatment applications were developed and perfected around the time of world war ii.
