On-Line Monitoring of Bioelectricity from a Microbial Fuel Cell Using Fishery-Industry Wastewater

Abstract

The fishery industry accounts negative environmental impacts to natural resources because of its wastewater with high amount of organic matter. The present study is focused on the production of bioelectricity using a single chamber of Microbial Fuel Cell (MFC), as well as the removal of suspended solids from a fishery industry wastewater. For this, an Arduino microcontroller and voltage sensors were used to monitor the bioelectricity production. The voltage peaked almost 750 mV in four cells at the end of 48 h. The removal of suspended solids reached almost a 87%. The harnessing of energy and wastewater treatment using a MFC is a promising method for valorization of wastes in the fishery industry.
