A simple in-situ methane enhancement system in mesophilic anaerobic digestion was developed to take advantage of the different solubilities of CO2 and CH4.The methane enhancement system consists of low solids plug-flow sorghum digester coupled with a leachate recycle loop to an external intermittent CO2 stripper.Quantitative evaluation of the system variables defined the effect of intermittent stripping of CO2 at different sweep gas flow rates on offgas methane content,biogas productivity and TVS removal efficiency.
