摘要：Central composite rotatable design experiment is used to study the effect of coagulation process for acid dye effluents and to optimise the variables such as dye concentration, coagulant dosage and initial pH, which influence the efficiency of colour and COD removal of dye effluents. The steel industrial wastewater (SIWW) FeCl3 rich is used for this study as an original coagulant to remove the acid red 14 dye solutions. A model has been obtained among decolourization, COD reduction and relevant parameters by means of variance analysis and obtained model was optimized. The efficiencies of decolourization and COD reduction for acid dye solution were accomplished at optimum conditions as 98% and 94%, respectively.
