Experimental determination of a critical temperature for maximum anaerobic digester biogas production

Abstract

This paper presents an experiment anaerobic digester system. The objective was to evaluate the optimal temperature for maximization of the biogas production through optimal constraining of the mesophilic temperature between log phase for the best fission of methanogenic bacteria. The temperature was varied over time over several days and the biogas production is recorded every after 24 hours(1 day) . Based on the experiment setup, the results show a higher biogas production proportional to the rise in temperature, though critical a temperature should not be reached that denatures the bacteria. This model has potential in the application for energy production especially in remote areas and communities.
