 Enhancement of biogas production in bio-electrochemical digester from agricultural waste mixed with wastewaterKalp Bhusan Prajapati and Rajesh Singh Renewable Energy, 2020, vol. 146, issue C, 460-468 Abstract: In present study anaerobic digestion was integrated with bio-electrolysis of agriculture waste mixed with wastewater for biogas production. The Bio-electrochemical digesters were operated at 20 mV, 40 mV, 80 mV, 120 mV and Control under anoxic conditions. An enhanced methane yield 175.17 ± 81.39 ml/g COD was obtained at 40 mV, whereas it was 105.36 ± 40.73 ml/g COD under control condition (without voltage supply). The total COD removal rate and organic conversion to methane was also enhanced at various applied voltages. The modeling parameters Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC) and F-test were used to test methane production to predict the performance. Exponential model for methane yield and Gompertz model for cumulative methane production exhibited the highest fit at 40 mV.
