Abstract
A cost and energy efficient method of liquid dairy manure solution treatment was investigated with the use of Microbial Electrolysis Chamber technology. The electrolysis chamber would precipitate phosphorus out of solution with the use of an applied voltage and the present microbes in the manure. It was seen that higher voltages around 1.0 V would remove roughly 35% of the total phosphorus out of solution. Reactors with a smaller induced voltage did not follow a steady trend and instead all remove between 8-16% of the total phosphorus in solution. This MEC treatment method does not remove as much as MFC and other removal technologies, but has proven to be very cost efficient. The economic feasibility of this experiment will allow it to be studied more in-depth and on a larger scale.
