Organics Removal
ouling resistance. DOWEX ion exchange resins are engineered to provide the optimum balance of organic removal and organic fouling resistance. The experts at Dow Water Solutions can help you nd the right resin and the right technology for your specic application.
Productivity. Many DOWEX resins are manufactured with uniform particle size (UPS) a technology invented by Dow researchers. UPS technology provides faster kinetics for higher ow rates, greater operating capacity, greater physical durability and increased resistance to fouling. Durability. DOWEX ion exchange resins are tough, durable plastic beads that remain stable when exposed to strong acids, bases and solvents. DOWEX ion exchange resins have been engineered by polymer chemists at Dow to be one of the toughest beads on the market. In many applications, DOWEX resins can be regenerated and reused for thousands of cycles. Reliability. DOWEX ion exchange resins provide reliable and dependable water purication, backed by more than 60 years of ion exchange manufacturing expertise. DOWEX resins are sold with guaranteed specications and certicates of analysis for every batch. DOWEX resins are manufactured with statistical quality controls under a certied quality system that complies with ISO 9000 standards.
Residential Applications
Options for Clearer, Better Tasting Drinking Water In many geographical areas, drinking water supplies are discolored due to tannins, which are generated by the decay of naturally occurring organic matter such as leaves and plants. DOWEX TAN-1 strong base anion exchange resin is specially designed to remove tannins, helping to improve the clarity and taste of home drinking water. In addition to its excellent tannin removal capabilities, DOWEX TAN-1 resin has a very porous structure that allows for easy regeneration. In many home drinking water systems, DOWEX TAN-1 resins can be added directly into existing water softeners to immediately begin producing clearer, better tasting water.
Industrial Applications
Options to Keep Demineralizers Running Strong Demineralizer applications for the removal of organics are demanding wand the anion resin must remove dissolved salts while handling organics effectively. In this application, operating capacity is the objective while organic fouling is the largest obstacle. DOWEX MARATHON 11 resin is an excellent solution for demineralizer fouling resistance, with distinct porosity to allow organic release while maintaining exceptional operating capacity. For installations where total ion exchange capacity is less critical, DOWEX MARATHON MSA resin has a macroporous structure that allows even better release of large organic molecules during the regeneration process. In addition, Dow offers DOWEX ASG acrylic resin as a cost-effective alternative in applications where higher temperatures and silica leakage are not a concern. More Options to Protect Demineralizers The use of an organic screen can provide further protection for industrial demineralizers. An additional bed of DOWEX MARATHON 11 resin can be installed upstream of the demineralizers, to remove organic molecules before they reach the demineralizers. When regenerated with a solution of alkaline brine, the organic screen will extend the life of the demineralizer resin. Options for Single Bed and Layered Bed Systems For demineralizer applications that require the highest capacity, along with complete organics removal and maximum fouling resistance, a combination of weak base and strong base anion resins may present the most effective solution. Layered beds with DOWEX resin combine the fouling resistance and high regeneration efciency of weak base anion exchange resins with the high operating capacity and more complete demineralization of strong base anion exchange resins. Layered bed regeneration technology is available from certied licensees of the DOWEX UPCORE ion exchange system. Options for Solvent Removal Naturally occurring organics are not the only contaminants that cause problems in industrial water applications. Solvents and other synthetic organics must also be removed to protect your system and purify your water supply. DOWEX OPTIPORE L493 resin is a broad spectrum polymeric adsorbent that is specially designed to remove a wide variety of chlorinated and organic solvents from water supplies. Options for Removal of Volatile Organics DOWEX resins can be used to purify air as well as water. DOWEX OPTIPORE V493 and DOWEX OPTIPORE V503 polymeric adsorbent resins effectively remove chlorinated and organic solvents from air streams, particularly in uid bed systems. In many cases, DOWEX OPTIPORE adsorbents can be used as a cost-effective replacement of activated carbon.
