Fig. 8From: A novel fragmented anode biofilm microbial fuel cell (FAB–MFC) integrated system for domestic wastewater treatment and bioelectricity generationThe voltage generated in the aerobic-MFC integrated domestic wastewater treatment system. Error bars indicate the standard deviation (SD). External load 1000 Ω. The p < 0.05 indicates a significant difference between the FAB–MFC and MFC. A circle with arrows indicates wastewater replacement and system shockBack to article page
