Performance of anaerobic baffled reactor (ABR) in treating domestic wastewater

Performance of a laboratory-scale Anaerobic Baffled Reactor (ABR) system treating chemically adjusted domestic (sewage) wastewater with variable strength of 100-500 mg/L was investigated at anaerobic condition (25-30 °C) for 81 days after reaching steady-state at different retention time of 1 d, 2 d...
