ABSTRACT
With the world’s population growing at a very rapid rate, the demand for improvements in technology also increases. This goes alongside with the rise in energy consumption, whiCh could, in turn, lead to energy depletion. One way of addressing this modern dilemmas the harnessing of the energy potential of Microbial fuel cells.
Microbial fuel cell utilizes the bacteria’s capability of synthesizing compounds present in waste water to produce electrical energy.
The study aimed to compare the efficiency of three different kinds of waste water in terms of voltage output. This study can help find an alternative source of energy while alternately utilizing wastewater, which is considered a pollutant.
The microbial fuel cells produced voltage in each of the three different wastewater and there is no significant difference across the different time intervals in each of the three samples and between the three samples. The mean voltage output in the first sample is 956.7 mV, for the second is 933.3 and for the third is 916.7. The highest mean voltage output for the first sample is 1100mV and the lowest is 895.33 mV. For the second, the highest mean voltage output is 1020.7mV and the lowest is 894.3mV. For the third and last sample the highest mean voltage output is 964.7 mV and the lowest is 877.3 mV.
