    Abstract

    Generation of raw palm oil mill effluent (POME) has rocketed over the past few decades. Due to palm oil is versatile in several applications for either food or nonfood uses. Conventional biological treatment is considered as one of the best methods to degrade organics in the POME. However, biologically treated effluent is unable to fulfill regulatory discharge standards decreed by Environmental Quality Act (EQA) 1974 in which post treatment is necessary. Thus, electro persulphate oxidation was introduced as a post treatment to further treat biologically treated POME to achieve stringent discharge standards for the first time. Using response surface methodology (RSM), optimum operational conditions such as current density, contact time, initial pH, and persulphate ( ) dosage were empirically determined. Hence, 77.70 of chemical oxygen demand (COD), 97.96 of colour, and 99.72 of suspended solids (SS) removal were obtained under 45 of current density, 45 of contact time, pH 4, and 0.892 of . Through analysis of variance (ANOVA), determination of coefficients ( ) were acquired with values of 0.9881, 0.9612, and 0.9589 for each quadratic model of COD, colour, and SS removal. High values as close to 1 indicate each quadratic model is statistically desirable and has reasonable agreement to experimental data. Upon these findings, electro persulphate oxidation had been proved that it is an effective post treatment due to its promising performance.
