Abstract
Anaerobic Digestion (AD) technology has gainedacceptance as an effective method for biogas production,providing an alternative energy source and wastewatertreatment solution. This study examines the influence of keyparameters, including influent Chemical Oxygen Demand(COD), Hydraulic Retention Time (HRT), and reactortemperature, on the %CH<sub style="text-align: justify; text-wrap-mode: wrap;">4</sub> content in biogas, which serves as anindicator of biogas quality, using a UASB reactor. A simulationmodel was developed in Aspen Plus, employing a 2k factorialdesign to analyze wastewater treatment and biogas productionprocesses. The results highlight HRT as the most influentialparameter affecting %CH<sub>4</sub> content. The study confirms thatlonger HRTs enhance organic compound degradation, therebyimproving CH<sub style="text-align: justify; text-wrap-mode: wrap;">4</sub> production efficiency by providing ample timefor substrate conversion. Higher influent COD levels alsocontribute to increased CH<sub style="text-align: justify; text-wrap-mode: wrap;">4</sub> yield by boosting available organicmatter. Optimizing these factors is critical for maximizing CH4production efficiency and improving wastewater treatmentquality, underscoring the importance of sustainable biogasproduction and wastewater treatment technologies.
