《Nitrite pre-treatment of dewatered sludge for microbial fuel cell application》
Polarization analyses were done on the MFCs operated with100 mg-N/L of nitrite addition and different pH(shown in Appendix A).The internal resistance of MFC for pH 5,6,7,8,and 9 was around 2080,1240,280,240,and 200Ω,respectively as shown in Table 2.The internal resistance of the MFC was lowest at pH 9(alkaline condition).The high internal resistance under acidic condition could be due to the inhibition effect of the FNA and unfavorable pH effect on the population of electrogenic bacteria at the anode.Under alkaline condition,the higher substrate availability compared to that under neutral condition,and lower FNA inhibition,contributed to the lower internal resistance within the MFC and thus resulted in higher power density for the MFC.This study showed that the alkaline condition combined with nitrite pre-treatment of sludge is a viable way to increase the power generation of a MFC.
