Enhancing Anaerobic Digestion Process: A Comprehensive Optimization Study

Abstract

Anaerobic digestion constitutes a series of chemical reactions facilitated by anaerobic microorganisms, wherein organic matter is converted into biofuels. We did a bibliometric study to comprehend the factors influencing the optimization of this process. This investigation underscored crucial parameters affecting methane and biogas production: temperature, pH, hydraulic retention time (HRT), carbon-to-nitrogen ratio, and sample preparation and treatment procedures. We recommend an average of parameters as T = 35°C, pH = 6, HRT = 21 days, and total chemical oxygen demand > 8.5 COD/m³.d to attain optimal outcomes, it is recommended to maintain. By adhering to these guidelines, the process can be enhanced, thereby fostering greater efficiency in biogas production.
