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 <i style="">p</i>H 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, <i style="">p</i>H and reaction time, is evaluated. Working with the wastewater <i style="">p</i>H 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.
