Abstract:
This paper aims to determine the mechanism by which microbial fuel cells convert chemical energy to electrical energy by the catalytic reaction of microorganisms in waste water/sewage treatment plants, to be predictable and controllable. Wide range of soluble activated sludge in waste streams as a source of bacteria from low to very high estimated statistically is responsible for risks of electric current inhibition. Thus a mathematical model is presented that describes: the bacteria growth due to appropriate amounts of biochemical oxygen demand contained in fed wastewater accompanied by amounts of generated electricity in each case. Simulations of the presented model showed that the bacteria growth energy, consumed energy of organic matter that contained in the fed wastewater and their subsequent generated electrical energy are always balanced according to law of conservation of energy. Accordingly, current approach accounts for variations in added activated sludge in fed wastewater should enable more accurate amount estimates for produced electricity.
