Abstract
Malaysia has emerged as one of the world's leading producers and exporters of palm oil products in recent decades. Raw palm oil mill effluent (POME) includes a high concentration of organic compounds and residual oil, resulting in a high biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS). It has a dark brownish colour and a high acidic value. Because raw POME is a highly polluting effluent, it cannot be dumped freely into any source of water without previous adequate treatment. In this study, air stripping pre-treatment is used in treating POME for anaerobic digestion process in producing biogas. Air stripping is a cost-effective technique that requires relatively little energy inputs and involves the transfer of free ammonia from wastewater to the gas phase. This research is conducted to analyze the best stripping time and initial pH of air stripping in reducing chemical oxygen demand (COD), total suspended solid (TSS) and ammonia nitrogen (NH3-N) of POME and to identify the amount of COD, TSS and NH3-N after air stripping pre-treatment. Laboratory-scale experiments of air stripping were conducted using 550 mL of POME from Felda Lepar Hilir 3 Palm Oil Mill at various initial pH and stripping time and constant operating condition of temperature and flow rate. The sample of POME collected was tested for its COD, TSS and NH3-N before and after the air stripping pre-treatment. The experimental results showed that the high COD, TSS and NH3-N removal efficiencies of 22.5%, 50% and 92.8%, respectively operating at initial pH of 12 and stripping time of 4 days. Higher pH and longer stripping time resulting higher COD, TSS and NH3-N removal efficiencies. The air stripping pre-treatment able to minimize the polluting effect by COD, TSS and ammonia nitrogen of POME thus produce a better quality of biogas.
