Microbial Fuel Cells (MFCs)

Microbial Fuel Cells (MFCs)

The global food industry, while vital, faces significant challenges in managing its wastewater. These effluents are typically rich in organic compounds, leading to high Chemical Oxygen Demand (COD) and considerable disposal costs, alongside environmental concerns. Traditional wastewater treatment methods can be energy-intensive and may not offer avenues for resource recovery. Our company introduces a transformative approach: Microbial Fuel Cell (MFC) technology, specifically engineered to address these challenges by converting food processing wastewater into bioelectricity while simultaneously purifying it, paving the way for a more sustainable and circular economy within the sector.

We specialize in providing cutting-edge Microbial Fuel Cell (MFC) services tailored to the unique needs of the food industry. Our core offering focuses on the dual benefits of sustainable wastewater treatment and energy generation, coupled with opportunities for high-value byproduct development. By harnessing the metabolic power of microorganisms, our MFC systems efficiently treat organic-rich effluents, converting waste streams into a valuable resource. This innovative approach not only mitigates environmental impact but also introduces new revenue streams and operational efficiencies for our clients.

Technical Principles

MFCs are bio-electrochemical devices that utilize exoelectrogenic microorganisms (microbes capable of transferring electrons externally) as catalysts. In the anaerobic anode chamber of an MFC, these microorganisms oxidize organic matter present in the food wastewater (the fuel). This process releases electrons (e-) and protons (H+). The electrons are transferred to the anode electrode and flow through an external circuit to the cathode electrode, generating electrical current. Protons migrate through a proton exchange membrane (PEM) or a salt bridge to the cathode chamber. At the cathode, electrons and protons combine with an electron acceptor, typically oxygen, to form water.

Technical Features

Our MFC technology offers several distinct advantages:

  • Direct Energy Recovery: Generation of electricity directly from wastewater, with our systems achieving a notable power density up to 1.2 W/m3.
  • High COD Removal Efficiency: Demonstrates exceptional organic load reduction, consistently achieving COD removal rates greater than 90%.
  • Reduced Sludge Production: Compared to conventional aerobic treatment, MFCs typically produce significantly less sludge, reducing disposal costs.
  • Ambient Temperature Operation: Operates effectively at ambient temperatures, minimizing energy input for heating.
  • Modular and Scalable Design: Systems can be customized and scaled to meet varying plant capacities and effluent characteristics.
  • Potential for Byproduct Valorization: Besides electricity, MFCs can be integrated into processes for recovering valuable biochemicals.

Application Areas

Our MFC technology is highly adaptable for treating various types of wastewater from:

  • Dairy processing
  • Breweries and distilleries
  • Fruit and vegetable processing
  • Sugar and confectionery manufacturing
  • Starch processing
  • Abattoirs and meat processing facilities.

Environmental Benefits

  • Reduced Water Pollution: Significant decrease in COD and BOD (Biochemical Oxygen Demand) of discharged water.
  • Lower Carbon Footprint: Reduces reliance on fossil fuels for wastewater treatment energy needs and potentially for plant operations.
  • Sustainable Waste Management: Transforms waste into a resource, aligning with circular economy principles.
  • Odor Reduction: Anaerobic digestion within the anode compartment can mitigate odor issues associated with raw wastewater.
