Attempts were made in this study to examine the efficiency of Fenton process combined with coagulation for treatment of water-based printing ink wastewater. Parameters affecting the Fenton process, such as pH, dosages of Fenton reagents and the contact time, were determined by using jar test experiments 98 % of turbidity and 54% of chemical oxygen demand (COD) and 14% of biological oxygen demand (BOD) could be removed at pH 4, 0.8 ml/L H2O2, 25 mg/l FeSO4 and 40 minutes contact time. The coagulation using fenugreek and ferrous sulfate (FeSO4) was beneficial to improve the Fenton process treated effluent in reducing the flocssettling time, enhancing turbidity, COD and BOD removal. The overall turbidity,COD and BOD removal reached 99%, 63% and 39.5% under selected conditions, respectively. Thus this study might offer an effective way for wastewater treatment of water-based ink manufacturer and printing corporation.
