Coulombic efficiency and power output from a dual chambered microbial fuel cell (MFC) using water samples from pond, canal and; treated and untreated sewage water at pH 4.5 and 5.5 indicated the following. The high pH 5.5 samples showed higher values for all the recorded parameters of voltage, current, current density, power density and coulomb i.e. efficiency. The highest voltage recorded was obtained with pond water (724 mV) and the lowest with untreated sewage water (492 mV). Maximum power density was obtained with pond water (190.6 mW/cm2) and lowest with untreated sewage water (71.04 mW/cm2). The maximum power of 4970.25 mW was obtained with treated sewage water unlike untreated sewage water due to the absence of sediment and oily material which inhibit electrical conductance. The high coulombic efficiency of 69%-75% using the various water samples indicates that bioremediation using MFCs is a feasible and economic strategy for water treatment.
