AMBERLITE™ Ion Exchange Resins are available in a very wide range of chemical compositions and polymer structures and have been used for decades in a high-value applications including water treatment in industrial and power generation plants.
AMBERLITE™ SCAV2 Ion Exchange Resin is Gaussian, Acrylic, Macroporous, Organic Scavenging Resin for Industrial Demineralization Applications. It is an exceptional scavenger used as an integrated part of the demineralization system to effectively remove natural organic matter (NOM) from waters under different operational circumstances, bringing water quality and operational stability back under control. Compared to conventional scavengers, AMBERLITE SCAV2 can save up to 85% on chemical costs when applied in Dow’s patent-pending organic scavenging process in which the scavenger is positioned between the cation and anion columns. This process can also reduce water use, and waste discharge volume/TDS, thus demonstrating that a process can be both environmentally and economically beneficial. AMBERLITE SCAV2 has the extraordinary flexibility to operate with two performance profiles depending on the regenerant used. The highest capacity for TOC removal can be achieved when regenerating this resin with hydrochloric acid. To achieve the lowest possible TOC leakage, it is recommended to regenerate with caustic. Compared to conventional strong base anion scavenger resins, the chemical properties of AMBERLITE SCAV2 provide outstanding adsorption capacity of undesired NOM species during service, and easy release of these compounds upon very mild (stoichiometric) regeneration conditions, making the use of (alkaline) brine no longer necessary. Because of its extra high loading capacity for organics, AMBERLITE SCAV2 TOC scavenging resin is the best product to use when throughput is expected to be limited by TOC rather than sulfate, as when the ratio of TOC (ppm C) to sulfate (meq/L SO4) is greater than 3.
