Assessment of performance mesophilic single-stage biogas digester for treating agricultural wastes

Urban Farm DB summary

This 24-week study in Ghana assessed the performance of an 8 m3 pilot-scale mesophilic single-stage biogas digester for treating urban agricultural wastes. Operating at 30 °C with various hydraulic retention times (HRTs), the digester used cow dung as inoculum and various plant and animal wastes as substrates. The system produced 3 m3 of biogas (60% CH4) daily, with HRTs of 23 and 26 days showing better removal efficiency for most parameters compared to 20 days.
