Electric power generation from treatment of food waste leachate using microbial fuel cell

Abstract

The volume of the air-diffusion cathode MFC was 234 mL (6.5 cm × 6 cm × 6 cm), with an effective volume of 200 mL (Fig. 1).Environ. Eng. Res. 2017; 22(2): 157-161 pISSN 1226-1025 https://doi. ABSTRACTSimultaneous treatment of food waste leachate and power generation was investigated in an air-cathode microbial fuel cell. A TCOD removal efficiency of 95.4 ± 0.3% was achieved for an initial COD concentration of 2,860 mg/L. Maximum power density ranged was maximized at 1.86 W/m 3 , when COD concentration varied between 60 mg/L and 2,860 mg/L. Meanwhile, columbic efficiency was determined between 1.76% and 11.07% for different COD concentrations. Cyclic voltammetric data revealed that the oxidation peak voltage occurred at -0.20 V, shifted to about -0.25 V. Moreover, a reduction peak voltage at -0.45 V appeared when organic matters were exhausted, indicating that reducible matters were produced during the decomposition of organic matters. The results showed that it was feasible to use food waste leachate as a fuel for power generation in a microbial fuel cell, and the treatment efficiency of the wastewater was satisfied.

Validity and Reproducibility of Counter Electrodes for Linear Sweep Voltammetry Test in Microbial Electrolysis Cells

“…[17][18][19]. Among MESs, MFCs are the system that generates electricity by degrading organic matter in wastewater using a microbial catalyst in the anode [20][21][22][23][24][25][26][27][28][29][30]. This technology has the potential to prevent direct fuel combustion and convert the chemical energy of organic waste into bioelectricity [31].…”

“…In contrast, bioremediation processes are more cost-effective, eco-friendly and thorough tactics to remove CNPs from waste water. Recent studies have shown that bioelectrochemical systems (BES) (including microbial fuel cells (MFC) [16][17][18][19], microbial electrolysis cells (MEC) [20].). There is the ability to remove refractory pollutants in water of those BES.…”
