Water treatment using Microbial Fuel Cells

MFCs are devices where bacteria can grow on one electrode, break down organic matter, while releasing electrons from the organic matter, it is similar to how we get energy, we eat food, we oxidize it, we remove electrons, we send these electrons to the respiratory

enzymes and then when we are done with them, we release them to oxygen. We eat

and breathe to do this. So when bacteria releases this electron, it creates a potential

of about 0.5 V; voltage time current is power, and that is how power is generated

from the system. In concept, a real simple system, having two electrodes on either

side of the container, bolted together, wastewater is added to the system and you

generate electricity.
