Polymerized ferric sulfate Cas No 35139-28-7

Polymerized ferric sulfate,as also know as PFS, Cas No 35139-28-7 is a chemical compound that is used as a coagulant in water treatment processes. It is a highly effective coagulant and is commonly used in the treatment of drinking water and wastewater. Polymerized ferric sulfate is formed by the polymerization of ferric sulfate, which is a salt of iron and sulfuric acid. The polymerization process creates larger molecules that have enhanced coagulation properties. When added to water, polymerized ferric sulfate reacts with impurities and contaminants, such as suspended solids, organic matter, and microorganisms. It forms flocs, which are larger particles that can be easily removed from the water through sedimentation or filtration processes. Polymerized ferric sulfate is preferred over other coagulants, such as aluminum sulfate (alum), due to its higher coagulation efficiency and lower dosage requirements. It also produces less sludge, which reduces the amount of waste…
