Overview

Country Fresh Dairy operates a dairy processing plant that currently provides a waste stream containing 175,000 gallons of whey. Currently Country Fresh Dairy is unable to dispose of the whey through Wyoming, MI wastewater system due to the high phosphorus content. The City of Wyoming Clean Water Plant is interested in providing a disposal method that will benifit both plants. Whey can be fermented into volatile fatty acids. The City of Wyoming Clean Water Plant is interested in using these volatile fatty acids in the stability of the phosphorus removal process.

Objective

To create a preliminary design for a whey bioreactor at the Wyoming Clean Water Plant in Wyoming, MI. The fermentation processin the bioreactor will optimize the ratio between propionic acid and acetic acid. This ratio is importatant in the stabilization of the phosphorus removal process. The team will also analyze the best method of transporting the whey from Country Fresh Dairy to the Wyoming Clean Water Plant.
