Abstract

The main objective of this study was to produce biodiesel from palm kernel oil and to purify the biodiesel washing water generated through adsorption, acidification, coagulation and filtration treatment processes. Removal efficiencies of these treatment processes were investigated by analysing biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, conductivity, total dissolved solids (TDS) and elements present in the biodiesel washing water (before and after treatments). The results of the trans-esterification process showed that the highest biodiesel yield of 87.6% was obtained at a reaction time of 65 minutes and methanol to oil mole ratio of 6:1.The overall removal efficiencies obtained using the stated water treatment processes were 65% (BOD), 38% (COD), 75% (TDS) and 94% (conductivity).The treated washing water met the waste water discharge standards of FEPA. Hence, adsorption, acidification, coagulation and filtration, were effective in treating biodiesel washing water.
