Abstract

Industrial tempeh wastewater contains high organic compounds that will negatively affect the quality of water ecosystem whenever discharged without any proper treatments. Biological treatment, in particular, anaerobic digestion is potential to be an effective solution for eliminating that contaminant. Considering its advantages, especially to produce methane gas, a study to evaluate the performance of anaerobic digestion process to reduce the organic substances in industrial tempeh wastewater was conducted. Sludge from cow manure biogas digester was used as inoculum to foster anaerobic decomposition process, hence special focus was given to elaborate the effect of F/M ratio on the methane production. Controlled batch reactors, with effective volume of 4L each, were employed with several operational parameters (pH, COD, VFAs) to be monitored in order to understand the process. Results elucidated that methane production was closely related to the composition of substrate to microorganism. The maximum methane production (8720 mL) followed by the highest organic reduction (67.7%) were found in F/M = 1.12. The measured operational parameters informed a sequence of process involved in the complete anaerobic decomposition. Accumulation of VFAs, because of higher substrate loading, tended to hamper methanogens metabolism resulted in low methane production. In addition to that, inoculum from biogas digester of cow manure was proved to play significant role in the anaerobic decomposition for industrial tempe wastewater. This finding is essential for arranging an effective yet low cost wastewater treatment for tempeh producers, together with that as a basis for further study.
