Abstract
Calcium peroxide was applied as an alternative oxidant in the Fenton's treatment of distillery slop. Three main factors, namely:calcium peroxide loading, catalyst loading, and pH, were screened for their significance on COD and color reduction using a 2k full factorial design. The three main factors passes the screening and were subjected to second order design using response surface methodology (RSM). A model equation was developed and was used for numerical optimization. The optimized condition in treating 15 mL of distillery slop used 3.17 g of CaO2, 15.35 mL of FeSO4, and a pH of 2.9. This condition obtained an 85.25% COD reduction and 97.07% decolorization. Though high reduction was obtained, the treated distillery slop still did not pass the DENR standard, thus additional treatment process is recommended. Th reagent cost for the modified Fenton's treatment process is PhP 26 651 per m³ of distillery slop. The modified Fenton's treatment found in this study was compared to the conventional Fenton's treatment conducted by Belarmino (1998). The comparison of COD and color reduction efficiency was indeterminate since the distillery slop treated came from different sources. In terms of reagent costing. modified Fenton's treatment is 25.18 times cheaper than the conventional Fenton's treatment making it more economical.
