Abstract

Current practice which utilized aerobic process to treat anaerobically treated palm oil mill effluent (AT–POME) still required much time due to the long hydraulic retention time (HRT) and start–up time. This experiment study the characteristics of AT–POME and the removal of organic pollutants from the solution by an aerated heterogeneous sono–Fenton process. Nano zero valent iron (nZVI) dispersed by vigorous aeration and low frequency ultrasound (24 kHz) were used in the treatment process. The effect of flow rate, power input, ultrasonic duration and reaction time on chemical oxygen demand (COD) removal from AT–POME was investigated and optimized. Results show that AT–POME contain 4568 mg/L of COD. Model predicted that approximately 93% of the COD content could be removed from AT–POME at optimum condition of the treatment process. The degradation data show that the COD removal from AT–POME via aerated heterogeneous sono–Fenton process experienced a biphasic behaviour and it well fitted with second–order kinetic model. The overall results indicate that aerated heterogeneous sono–Fenton process is a promising way to accelerate the removal of COD from AT–POME, thus could save the overall treatment time for raw palm oil mill effluent (POME).
