The document discusses treatment of wastewater from resin manufacturing industries using coagulation-flocculation. It begins with an introduction to resins, their types and uses. It then discusses the coagulation and flocculation processes and mechanisms. Literature review covers various studies on treatment of wastewater from different industries like textile, distillery using different coagulants. It also discusses characteristics of wastewater from phenol formaldehyde and ABS resin industries. The objectives of the work are to characterize the wastewater and optimize treatment process using composite coagulants to remove pollutants like acrylonitrile, COD, BOD, TSS. Comparison of different treatment systems for acrylonitrile containing wastew
