The statistical model developed predicted optimal operating
conditions for SMFC configuration. Similar COD removal and TN
removal, as predicted by model, in all four SMFCs during validation
experiments suggestthatthe statisticalmodel predicted the performance
of SMFC reasonably well. However,the present optimization
experiments established the trend of substrate degradation and
power generation that could be obtained at different levels of operating
variables under study and indicated the effects among the
operating variable on the responses expected from the SMFC, i.e.,
COD removal, TN removal and power recovered.
