title: Biopower generation from kitchen wastewater using a bioreactor.
abstract: This research provides a comparative study of the power output from mediator-less and mediator microbial fuel cells (MFCs) under aerobic and partially anaerobic conditions using kitchen wastewater (KWW) as a renewable energy source. The wastewater sample was subjected to different physical, chemical, biochemical, and microbial analysis. The chemical oxygen demand (COD), biochemical oxygen demand (BOD), and power output values were greater for the fermented samples than the non-fermented samples. The power output of samples was compared through the development of MFCs by using sand-salt bridge and agar-salt bridge. The H2 that was produced was converted to atomic hydrogen by using the nickel-coated zinc electrode. In addition, the power output was further enhanced by introducing air into the cathodic chamber, where oxygen reacts with the protons to form pure H2O. The study showed that the power output was increased with the increase in COD and BOD values.
