1,200 kWh/million gallons (MG) Average Energy Used:

  • 1 MGD  2,200 kWh/MG
  • 10 MGD  1,200 kWh/MG
  • 50 MGD  1,000 kWh/MG

Energy Use Scales with Size

  • 45%
  • 17%

Onsite wastewater treatment system – Septic systems

  • Conventional methods using gravity flow – no energy costs, relatively cheap,

anaerobic

  • 20% of U.S Homes use septic systems to treat their wastewater (EPA)
  • Septic tanks need regular maintenance and lack of it leads to groundwater

pollution

Potential applications for the microbial battery technology to be used in wastewater treatment in Septic systems

  • Two companies Emfcy and Proningeer are scaling MFC technology to be able

to use it in onsite wastewater treatment

  • Using a greener technology might entail subsidies from The ARA (America

Recovery Act - Kit Rosefield from California Onsite waste water association (COWA).

  • Energy generation from wastewater treatment in septic tanks

will be of interest in developing countries without proper access to municipal sewers and electricity

Application: Microbial batteries in aquaculture

  • System types
  • 2004 EPA effluent guidelines
  • Information from “getting out of the building” step
  • Pathogen removal is key problem
  • Modularity/easy addition

Conclusion – Several Issues Remain

  • Additional R&D required

– Cost high (materials, maintenance, labor, etc) – Efficiency low

  • Regulatory Considerations
  • Operational Considerations

– Existing infrastructure
