Anaerobic Digestion of Cow Dung and Rumen Fluid for Biogas Production

The Anaerobic Digestion of Cow Dung and Rumen Fluid for Biogas Production was investigated using a 75L bio-digester. The substrate mixture, comprising cow dung and rumen fluid in a 1:1 ratio, was anaerobically digested with a water-to-substrate ratio of 1:1. The digester was stirred thrice daily to ensure optimal mixing and biogas production. Over a 14-day retention period, biogas production was monitored, and the resulting gas composition was analyzed. The biogas yielded 57.99% methane (CH<sub>4</sub>), 39.99% carbon dioxide (CO<sub>2</sub>), 2.00% oxygen (O<sub>2</sub>), 0.01% hydrogen sulphide (H<sub>2</sub>S), and 0.01% water vapor. The findings demonstrate the feasibility of co-digesting cow dung and rumen fluid for biogas production, highlighting the potential for sustainable energy generation from agro-industrial waste. The study reveals that the anaerobic digestion process was effective in converting organic waste into a valuable energy resource. The presence of methane as the primary component indicates the potential for energy generation, while the low oxygen content confirms the anaerobic nature of the process. The results suggest that co-digestion of cow dung and rumen fluid can enhance biogas production, offering a promising solution for waste management and renewable energy production. This study Reveal the optimization of biogas production from agro-industrial waste, contributing to the development of sustainable energy solutions. The outcomes of this research have significant implications for Nigeria's energy sector, where abundant agricultural waste can be harnessed to meet energy demands.
