Ion Resin Exchange Water Treatment

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

Ion resin exchange water treatment. 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. 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 exchange ix is the reversible interchange of ions between a solid and a liquid such as water. Customers can send their ix resin in tanks super sacks or totes to us for regeneration.

Among few companies worldwide with the entire range of technologies processes products services we are able to provide solutions for every sector industrial institutional municipal and household for both. 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. Resin beads used in ion exchange water treatment. Two bed demineralizers have two vessels the first containing cation resin followed by a separate vessel containing anion resin.

During regeneration the resin is separated into distinct cation and anion fractions as shown in figure 8 12. This structure gives the ion exchange resin bead certain physical properties. 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. Effective ion exchange for challenging water treatment needs.

As water flows through the resin bed the ion exchange process is repeated many times polishing the water to a very high purity. The hardness ions ca and mg move into the resin beads and each of these divalent. Rohm and haas ion exchange ion exchange introduction 4 fd sep 2008 to soften water you take a cation exchange resin on which the mobile ion inside the beads is sodium na and you pass the hard water through a column filled with the sodium form resin. 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.

The majority of resins in use today have a styrene divinylbenzene copolymer bead structure.
