Abstract

The anaerobic baffled reactor is a high rate digester and the biogas produced by this digestion can be used to produce power generated by its combustion. Methane produced by the anaerobic digestion of the Anaerobic Baffled reactor (ABR) was measured and studied by performing a Bio-methane Production (BMP) test. BMP tests are widely used in studies concerning the anaerobic digestion of organic solids in wastewater treatment. They are a useful tool to improve the knowledge on the anaerobic digestion process to treat organic wastes. Sludge Activity and Substrate biodegradability is important to identify because the measurement of the activity of microorganisms involved in wastewater treatment delivers information about biochemical processes responsible for substrate utilization or the speed of methane produced by substrate. Therefore, the goal of the research was to characterize the ABR sludge and learn more about the degradation kinetics of both ABR sludge and ABR wastewater. The findings after implementing this test show that anaerobic digestion with complete mixing is most ideal because it increases the contact time of microorganism to substrate ratio, which rises the methane production rate unlike non-stirred conditions that limit diffusion. On the other hand, this limitation of diffusion is closer to real ABR conditions where there is less than optimal methane gas production. Additionally, ABR wastewater was found to be less digestible than acetate, and the total fraction of wastewater had a higher biodegradability than the soluble wastewater fraction due to the difference in particulate matter.
