Removal of Odors from Swine Wastewater by Using Microbial Fuel Cells

Abstract

A single-chamber microbial fuel cell (MFC) was used to reduce 10 chemicals associated with odors by 99.76% (from 422 ؎ 23 g/ml) and three volatile organic acids (acetate, butyrate, and propionate) by >99%. The MFC produced a maximum of 228 mW/m 2 and removed 84% of the organic matter in 260 h. MFCs were therefore effective at both treatment and electricity generation.

Electricity Generation Coupled with Wastewater Treatment Using a Microbial Fuel Cell Composed of a Modified Cathode with a Ceramic Membrane and Cellulose Acetate Film

“…Kim et al [13] produced 228 mW/m 2 of electric energy at an electric potential of 0.4 V from 165 ml in a singlechambered MFC with 1,000 Ω of external resistance, consuming about 6,946 mg/l of COD. Jia et al [12] reported that 1.7 mW/m 2 of electric energy was produced by an MFC using denitrifying bacteria as an electron acceptor with a coulombic efficiency of 7%.…”

MFCs have also been used for ammonium oxidation and biological denitrification, in which the reducing power generated by exoelectrogenic bacteria may be converted to metabolic energy by denitrifying bacteria [5,6].…”

Bioelectricity Production and Comparative Evaluation of Electrode Materials in Microbial Fuel Cells Using Indigenous Anode-Reducing Bacterial Community from Wastewater of Rice-Based Industries

“…A variety of wastewater have been used in MFC as fuel such as domestic sewage with voltages ranging from 0.43-0.44 V (Ahn and Logan, 2010) and 0.32±0.01 V (Liu et al, 2004);Huang and Logan, 2008 were able to produce the power output of 400 mV -420 mV using paper and pulp wastewater; maximum voltages generated in an MFC using Rice mill wastewater were 0.304 V and 0.172 V (Behera et al, 2010); brewery wastewater was able to produce 0.071 -0.330 V (Feng et al, 2008); a current of 2.12-2.48 mA were recorded using distillery wastewater (Mohanakrishna et al, 2010); in odor-producing compounds treatment of swine wastewater a maximum of 0.4 V were recorded (Kim et al, 2008); Oil refinery wastewater produced the maximum voltage output of 0.355 V (Majumder et al,2014). A maximum open-circuit potential of 2.2 V was obtained using rice mill wastewater with the anode in batch-fed mode of operation (Daniel et al, 2009); 0.4908 V achieved using starch processing wastewater (Lu et al, 2009); 0.421V was produced using starch processing wastewater (Park et al, 2001), 0.207±0.03 V to 0.350±0.025 V were recorded using municipal Wastewater (Mohanakrishna et al, 2010); high open circuit voltage (OCV) of 0.810 V were reported using dairy industry wastewater (Lu et al, 2009), 0.689 V was generated using coconut husk retting wastewater (Park et al, 2001), near 1 V open circuit potential (OCV) were (Baranitharan et al, 2013).…”

Electricity Generation from Swine Wastewater in Mediatorless Single‐Chamber Microbial Fuel Cells

“…[20][21][22] In most cases, they used raw swine wastewater as inoculum as well as substrate after removing large particles. Maximum power densities in the range of 200 and 260 mW/m 2 using full-strength wastewater were obtained.…”
