Justin Buck, Cambrian Innovation
Modular, turn-key waste water to energy systems using electrically active microbes. The amount of energy in waste water is proportional to the BOD level.
Uses exo-electrogenic organisms like geobacter and shewanella. Geobacter is efficient and shewanella can operate in a wider variety of circumstances (a generalist).
They can build microbial fuel cells using waste water as a fuel.
Cambrian is looking at water treatment, electricity generation, and information from the flow through the system.
Ecovolt - world's first bioelectrically enhanced waste water treatment system, a biogas producer which can remove more BOD from water than traditional methods and produce more biogas. Does not yet deal with heavy metals and pollutants like benzene. A primary treatment system that removes soluble BOD, provides heat through hot water, biogas, and electricity. Payback from less than a year to three years. 20,000 gallons per day per module. Working on a WEPA - water energy power agreement. The electricity comes from burning methane.
Scaling is the most difficult thing.
