Abstract

The synergy of Fenton's oxidation and electochemistry (known as Electro-Fenton (EF) process) was used as an alternative water remediation technique to treat desiccated coconut manufacturing plant wastewater. A 3ᵏ factorial experimental design was applied to investigate the effects of FE²⁺ dosage H₂O₂ dosage and operating current on COD reduction efficiency and reaction time index(the time for the reaction to reach the peak temperature). Statistical analyses showed that the main factors (Fe²⁺ dosage, H₂O₂ dosage and current) and the interaction between the Fe²⁺ dosage and operating current interaction have significant effects on COD reduction efficiency though too high levels of current and H₂O₂ dosage were also observed to lower COD reduction efficiency. Statistical analysis also showed that only the main factors have significant effect on the reaction time index of the EF treatment and high level of current would lengthen the reaction time index. An "exploratory" optimization was made since statistical modeling for the responses of COD reduction efficiency and reaction time index resulted to a significant lack of fit. By response surface methodology, the suggested volume (mL0 ratio of Fe²-H₂O₂-top-wastewater was 6.67:66.58:200 mL under 857.84 mA preliminary costing revealed a high cost of treatment due to energy cost.
