| 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. |
