摘要：Textile industry is one of the major industries that pose environmental concern, whereby the wastewaterproduced by it is characterized with high temperature, pH, colour and COD. A hybrid coagulant whichis consisting of polyacrylamide aided magnesium chloride was applied in treating textile industrialwastewater. Four independent factors, i.e. pH, dosage, agitation speed and time were used todetermine their effects on colour removal (%) and COD reduction (%). All independent factors wereproved to have significant effect on the colour removal and COD reduction. The optimal operatingparameters 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 theeffluent is safe to be discharged into the environment.
