Biogas Production Optimization from POME by Using Anaerobic Digestion Process
The aim of this research is to optimize Biogas production from palm oil mill effluent (POME) with organic loading rate (OLR), carbon-to-nitrogen (C / N) ratio and pH using anaerobic processes. This study explores the potential of POME in anaerobic digestion with the perspective to develop a constructive process to treat POME and it can significantly contribute to biogas production. Design of Experiment (DoE) is used to determine the inputs (OLR, C/N, pH) for conducting research to achieve outputs (biogas production). Based on Central Composite Design (CCD), 5 levels of inputs for pH, C/N, and OLR are obtained. The findings of data analysis from Response Surface Methodology (RSM) shows that pH of 6.9, C/N of 30, and OLR of 6 VSS g/L.d have contributed to obtaining 3.8 L/day biogas production from POME. Treating POME anaerobically has proven to be successful because it is value-effective and environmentally friendly. The consequences of the research outcome in terms of environmental pollution are huge. The study suggests implementing a pilot scale study for producing required data is needed in developing economic scale POME treatment plant.
