Comparative studies on cleaning effect and electricity generation capacity of microbial fuel cell in different water quality conditions

Microbial fuel cell is considered to be a promising sustainable technology to meet increasing energy needs. It can produce electricity directly from wastewater, and this opens the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity. Low energy output is one of the major bottlenecks that limit industrial applications of MFC. This paper mainly carries out some comparative studies on the electricity production of microbial fuel cell system with different kinds of wastewater. An experimental system of microbial fuel cell including data collection session is set up first. Then, five kinds of wastewater are used in the microbial fuel cell to test their respective electricity production. It is shown by analyzing the experimental data that all kinds of wastewater used in this paper have the ability of generating power, especially, the power generation capacity of construction wastewater and mess hall wastewater are considerable. © Research India Publications.
