The experimental data obtained showed that it is actually possible
to generate electric power from the waste water. The distance between
the cells’ anode and cathode deter-mined the magnitude of the voltage
created between the electrodes. The shorter the distance between the
anode and the cathode, the higher the voltage developed between the
electrodes. Using soil as a membrane greatly increased the cell’s internal
resistance therefore the use of soil is not viable option for electricity
generation. The MFC cells showed higher treatment efficiency rates
than ordinary waste treatment ponds under similar environmental
conditions (Figure 6). The highest treatment efficiency was 80% after
20 days whereas that of the control was 30% after the same number of
days. The constructed practical model developed a maximum volt-age
of about 217 mV on day one from the introduction of the MFC fuel.
