Abstract

Anaerobic co-digestion was carried out at mesophilic condition (37°C) in 1-L media bottles with a working volume of 800 mL consisting of different dilution ratio of distillery wastewater (DWW), press mud, bagasse, and inoculum. Distillery waste water was diluted with tap water at two different ratios (2:3 and 3:2) and in two sample bottles, micronutrients were added. Batch test results showed that press mud mixed with diluted distillery wastewater with and without additional micronutrients gave the highest methane yield of 61.3% and 78.23% (v/v), respectively. Methane yield is affected by the sensitivity of microorganisms to pH variations. In this study, optimum pH was found out to be 5.0 to maximize methane yield. COD/BOD ratio was also evaluated and the optimum initial COD to BOD ratio of the sample that yields higher methane yield ranged from 1.8 to 2.6 which indicate that it is amenable to biological treatment. Meanwhile, the optimum C/N ratio is found to be in the range of 72:1 and 78:1. For the effect of dilution, higher methane yield occurred at higher dilution ratio. Moreover, anaerobic co-digestion of organic sugar waste was more favorable in biogas production compared to mono-digestion of a single biomass. Lastly, effect of micronutrients to the digestion and heterotrophic plate count were evaluated in this study.
