摘要：
This study focused on treatment of sulfate-rich produced water (PW) using microbial fuel cell (MFC) with biotic anode (bAC) and abiotic cathode (aCC) separated by a cation exchange membrane (CEM). MFC was operated under varied circuitry modes open circuit (OC-without resistance) and closed circuit (CC-applied resistance (1k Omega)) to evaluate and assess the removal of sulfates and salts with simultaneous carbon utilization. The OC and CC operations depicted sulfates removal efficiency of 38% and 56%, salinity removal of 12% and 21% and COD removal of 47% and 58%, respectively. Both OC and CC showed K+ decrement in bAC and increment in aCC with a comparatively higher efficiency of ionic mobility in CC operation. Maximum open circuit voltage (OCV) of 498 mV (OC) was observed with redox catalytic peak currents from cyclic voltammetry [Anode/cathode, 3.5/ -4.9 mA (OC); 6.9/-7.9 mA (CC)]. Dominance of Proteobacteria and Actinobacteria with specific enrichment of sulfate reducing bacteria (SRB) and halophiles was observed in bAC at the end of operation.
