Abstract

Palm Oil Mill Effluent (POME) wastewater generation has been rocketed in the past few decades due to the ever increasing demand for the usage of fats and oils. Conventional biological treatment has been undoubtedly the best way to reduce the organic matters but insufficient to meet the discharge standard by the local authority. As a result, further treatment is needed to meet more stringent discharge standards. The present study indicates that integrated post-treatment would further treat wastewater so that the wastewater could achieve the required discharge standards. Using response surface methodology (RSM), a few operational parameters would be prioritized such as current density, reaction time and pH that were empirically determined by optimization via RSM. The optimum performance of 69.56% COD, 97.80% colour and 99.64% turbidity removal were obtained under 56 mA/cm2 of current density and a reaction time of 65 minutes with pH 4.5. Through the regression analysis, R2 , was found to be 0.86, 0.93, 0.97 and 0.86 for colour, COD, turbidity removal efficiency and pH respectively. Upon these findings, electro oxidation process at specified level maybe used as a post treatment technology that is effective and efficient before final discharging so as to meet the requirements.
