Abstract: The present study deals with treatment of coffee pulping wastewater using Fenton’s oxidation process. The coffee pulping wastewater used for the present study is characterized by low pH with high concentration of COD, ammonia nitrogen, nitrate nitrogen and phosphorous with BOD/COD ratio varying from 0.037 to 0.050. The effect of different operating conditions, namely Fenton dosage, mixing speed, pH and reaction time, is evaluated. Working with the wastewater pH of 6.42, mixing speed of 25 RPM, molar ratio of 12.43 and mass ratio of 0.60 for reaction time of 60 min makes possible the COD conversion of 84.39%. The percentage removal of other pollutant parameters, such as ammonia nitrogen, nitrate nitrogen and phosphorous, is found to be 90.75, 57.5 and 80% respectively.
