Textile industrial wastewater treatment by polyacrylamide aided magnesium chloride hybrid coagulant

Research output: Contribution to journalArticle

Abstract

Textile industry is one of the major industries that pose environmental concern, whereby the wastewater produced by it is characterized with high temperature, pH, colour and COD. A hybrid coagulant which is consisting of polyacrylamide aided magnesium chloride was applied in treating textile industrial wastewater. Four independent factors, i.e. pH, dosage, agitation speed and time were used to determine their effects on colour removal (%) and COD reduction (%). All independent factors were proved to have significant effect on the colour removal and COD reduction. The optimal operating parameters were fixed at pH = 12.00, dosage = 1000 mg/L, agitation speed = 100 rpm and agitation time = 5 minutes, in attaining colour removal and COD reduction of 82.83% and 26.38%, respectively. Secondary treatment is needed to reduce COD of the textile industry wastewater to ensure that the effluent is safe to be discharged into the environment.
