Abstract

The performance and applicability of electron-Fenton method for the COD reduction on a local dairy processing effluent with a low biodegradability of 0.37 was studied. Individual and interaction effects of hydrogen peroxide, iron catalyst and current on COD reduction efficiency and time-to-reach-peak-temperature were studied. Results showed that increasing the individual dosages of H₂O₂ and catalyst rendered significant favorable effects on COD reduction, but current supply was insignificant. For time-to-reach-peak-temperature, only iron catalyst dosage gave significant results. All intersections among the treatment factors gave insignificant results. Insignificance of treatment factors was attributed to competing reactions, electrode fouling due to cathodic deposition and limited dosage/supply of the factors. Using response surface method with three-level factorial design,a quadratic model was recommended for relating the treatment factors both response variables. the best condition in terms of catalyst-to-H₂O₂-to-effluent ratio condition was approximated at 1.00:7.37:37.11 based on an operating current range of 0.3 to 0.9 A. Based from the response surface model, the predicted most favorable COD reduction efficiency and time-to-reach-peak-temperature of 84.2hp 4,172.30 per cubic 5% and 16.12 minutes, respectively. The corresponding treatment cost at the recommended treatment condition was php 4,172.30 per cubic meter of wastewater.
