Performance Analysis of a Dual Chamber Microbial Fuel Cell Using Kitchen Wastes as Substrate

This research paper analyzes the performance of MFC under aerobic condition for drain sludge, textile sludge, tannery sludge and Buriganga sludge. Kitchen wastes (rotten rice, vegetables) were utilized as source of carbohydrates for the growth of bacteria. A total number of four experiments were conducted throughout the research work and all of them were observed for seven days. Voltage, current density and power density were recorded for each experiment to analyze the electrical potential of the Microbial Fuel Cells constructed as well as environmental parameter related to waste water treatment like Biological Oxygen Demand (BOD) was also observed in this study. In this study 319.6 mV was measured as maximum voltage while 30.1 mA/m
²
and 9.62 mW/m
²
were recorded as maximum current density and power density respectively for textile sludge. The BOD reduction was found to be 45.45%. 39.90%, 44.14% and 33.10% for drain sludge, textile sludge, tannery sludge and Buriganga sludge respectively.
