DOT ID & Guide. WebA common dechlorination process is the injection of sodium bisulfite or metabisulfite, classified as a chlorine scavenger. Eventually, the resin beads contain nothing but calcium and magnesium ions and no sodium. When dosed online at high dosages, it is an oxygen scavenger and many biofilm forming bacteria are anaerobic, making oxygen scavenging useless. WebSodium metabisulphite is a widely used white powder for the removal of chlorine from the water system. By combining the use of a miscible organic solvent with saturated sodium bisulfite, aldehydes and reactive ketones can be successfully transformed into charged bisulfite adducts that can then be separated from other organic components of a mixture by the introduction of an immiscible organic layer. WebSodium Bisulphite is one of the mostly widely used dechlorination chemicals. 7631-90-5 RTECS No. Rufen Sie uns an unter Energy XPRT

Sulfite salts are oxygen scavengers which can decrease oxygen levels in water. Dechlorination is performed because chlorine can form deposits on the internal edges of industrial equipment, cause health issues (e.g., choking) or lead to corrosion. endobj
