Brooks and streams are naturally aerate water in bubble brooks. Their tools are rocks, and gravity, disturbing and oxygenating the water and breaking down organic content.
The result: life in the riverbed thrives - a healthy stream, full of bio-diversity.
Natural aeration is the inspiration and basis for modern wastewater treatment...
Municipal & Industrial Aeration
This is how large-scale wastewater is aerated - blowing air into water 24/7. It's very energy intensive (even with newer, efficient systems). Mechanical aeration uses 3% of US Electricity (120,000 GWh of power.) Every year. That equals more than 89,000 Metric Tons (annually) of CO2.
So, although industrial aeration is effective, it's costly. Financially and environmentally.
Of course, there is another way...
How MFCs Work
A biofilm of naturally-occurring microbes (mostly electrogenic) live on the Anode (left), consuming organic waste and generating electrons.
On the right, our set of proprietary materials are assembled into a conductive cathode, to accept the electrons. (AKA, DC Power)
Notice, rather than aerate all the water, a very small amount of Oxygen is provided to the cathode, as the ultimate electron acceptor.
The Result: Microbes treat the waste, as usual. And your wastewater treatment becomes Energy-Positive, without the high power bills. (The blowers are off!)
