Effects of potassium permanganate catholyte and salt enrichment on electricity generation and human wastewater treatment in microbial fuel cell were investigated. Water samples were collected from FUTO male student hostels. Microbiological and physicochemical analyses were carried before and after the experiment. Tests were conducted using a double chamber microbial fuel cell (DCMFC) containing four electrodes in each chamber. It was observed that the maximum average voltage of 1.10 V for carbon was obtained while on addition of salt, the maximum average voltage was 1.16 V. The maximum average voltage of 1.05 V for copper was obtained while on addition of salt, the maximum average voltage was 1.06 V. The results revealed that the microbial fuel cell with carbon electrode had the highest value of the efficiency while reducing the TOC by 93.54% while the least efficiency was observed in microbial fuel cell with copper electrode (salt enriched) having an efficiency of 26.90 % which is an increase in the copper level instead of a decrease. With microbial fuel cell technology, our environment can be safer and power can be generated hence obtaining a self-sufficient waste treatment method. The calculated waste water treatment efficiencies served as a base for the identification of the treatment capacity of the microbial fuel cell
