This study conducts a comprehensive statistical analysis to evaluate the impact of different treatments on biogas production and assesses the effectiveness of anaerobic digestion processes. Results from ANOVA indicate a significant effect of treatment on biogas production (F-value = 6.28, p < 0.05), with the 55°C GAC treatment showing notably higher biogas yields. Post-hoc comparisons further confirm the positive influence of GAC addition and higher temperature on biogas production, with the 55°C GAC treatment significantly outperforming all other treatments (p < 0.05). Analysis of total solids (TS) and volatile solids (VS) before and after digestion demonstrates a significant reduction in both TS and VS content across all treatment conditions. For instance, the 37°C treatment showed a decrease in VS from an initial value of 6.38% to a final value of 2.96%, while the GAC 37°C treatment exhibited a decrease from 6.38% to 3.26%. Similarly, the TS decreased from 8.01% to 4.01% in the 37°C treatment, and from 8.01% to 4.89% in the GAC 37°C treatment. Removal efficiencies of volatile solids show that higher temperatures enhance removal rates, with approximately 53.6% removal efficiency at 37°C and 60.9% at 55°C, while the presence of GAC slightly reduces removal efficiency compared to treatments without GAC. The study also compares two kinetic models, the first-order kinetic model and the Cone model, to analyze biogas production kinetics. While the first-order model provides insights into the exponential stage of gas production, the Cone model offers a better fit to the data and predicts methane yield more accurately, with root mean square prediction error (rMSPE) values ranging from 1.7087% to 6.836%. These findings contribute to advancing understanding and refining models for optimizing anaerobic digestion processes and maximizing biogas yields for sustainable energy production.
