Membrane less microbial fuel cell (ML-MFC) is one of the attractive approaches for the simultaneous electricity generation and wastewater treatment. In this present paper, electricity generation by ML-MFC has been studied in continuous mode. Several experiments such as effect of aeration in cathode compartment, sludge concentration, initial substrate concentration and the COD removing capability of the ML-MFC were investigated to maximise the performance. A maximum power density of 8.98mW/m
was observed at the current density of 34.02 mA/m
. COD removal was detailed from 44% to 54% in all experiments.
