Abstract—Sediment microbial fuel cells (SMFCs) are the auspicious technology, which can recover energy from wastes in low-cost, but the low-level power recovery from these devices is great obstacle towards its community acceptance. The performance of SMFC could be prominently improved by using graphene oxide – Zeolite modified anode (GZMA) and application of V2O5/Vulcan XC composite catalyst on cathode. The SMFC with GZMA and V2O5/Vulcan XC composite catalyst (SMFC-4) was able to recover a power density of 15.2 mW/m2 from fresh water aquaculture pond. This power density was found 2.49-times higher than the SMFC using GO modified anode (GMA) and without catalyzed cathode (SMFC-1). However, GMA and V2O5/Vulcan XC composite catalyzed cathode in SMFC-2, the power density of 6.02 mW/m2 obtained from SMFC-1 could be enhanced to 10.6 mW/m2 for SMFC-2, which was found slightly higher than the SMFC using GZMA and without catalyzed cathode (SMFC-3, 10 mW/m2). The wastewater treatment efficiency in terms of chemical oxygen demand and total kjeldahl nitrogen from aquaculture water was found highest in SMFC-4 with a value of 89.5 ± 1.9% and 64.2 ± 1.7%, respectively. In addition, at the end of each batch cycle i.e. after 15 days of continuous operation, all the SMFCs were found to be capable of reducing the ammonia nitrogen up to desired level (i.e. < 1 mg/L) for culture of India major carp.
