Internal resistance of the cells generally increased with time
(Figure 8). Since ions are responsible for conductivity in the cells
then the increase in resistance must be attributed to the decrease in
electricity conducting shuttles/carriers [12]. The electricity conducting
shuttles present in sew-age include sulphate ions, nitrates, nitrites,
ammonium, sulphides, hydrogen ions, phosphates and other salt
ions. The concentration of ions like the sulphates, nitrites, nitrates and
others were reduced since they are electron acceptors. The sulphate is
reduced to sulphide and then given off to the atmosphere as hydrogen
sulphide which exhibits an undesirable odor. This odor is given out in
high concentration during the first three days of cell life. The nitrates
and nitrites are also given off to the atmosphere through the nitrogen
cycle. The process of electron acceptor loss led to the decrease in
concentration of the ions in the three cells. This led to the decrease
