Model-based optimization of microaeration for biogas desulfurization in UASB reactors

Original language description

During anaerobic treatment of sulfate-rich wastewater, biogas with a high concentration of hydrogen sulfide (H2S) is produced. Since H2S is toxic to humans and can cause corrosion of concrete and steel, it needs to be removed before using the biogas for energy and heat production. Biogas desulfurization can be achieved by blowing small amount of air into the anaerobic reactor, a process which is termed &quot;microaeration&quot;. In this study, the generally accepted Anaerobic Digestion Model No. 1 (ADM1) was extended with sulfate reduction and sulfide oxidation to optimize the microaeration process during the anaerobic treatment of sulfate-rich wastewater. The resulting model, termed ADM1-S/O, was validated against experimental data from two reactors operated under anaerobic and microaerobic conditions, showing a good description of H2S concentrations in the biogas. The biomass composition in both reactors was not significantly affected by microaeration. Additionally, scenario analyses were carried out to assess the effect of the influent S:COD ratio and the aeration intensity (O-2:S ratio) on the steady state reactor behavior.
