A review of the operating parameters on the microbial fuel cell for wastewater treatment and electricity generation

摘要

Environmental and economic considerations suggest a more efficient and comprehensive use of biomass for bioenergy production. One of the most attractive technologies is the microbial fuel cell using the catabolic activity of microorganisms to generate electricity from organic matter. Microbial fuel cell (MFC) has operational benefits and higher performance than current technologies for producing energy from organic materials because they convert electricity from the substrate directly (at ambient temperature). However, MFCs are still not suitable for high energy demand due to practical limitations. The overall performance of an MFC depends on the electrode material, the reactor design, the operating parameters, substrates, and microorganisms. Furthermore, the optimization of the parameters will lead to the commercial development of this technology in the near future. The simultaneous effect of the parameters on each other (intensifier or attenuator) has also been investigated. The investigated parameters in this study include temperature, pH, flow Rate & hydraulic retention time, mode, external resistance, and initial concentration.
