Wastewater Carbon Source Comparison - Case Study

Three batch reactors were constructed using 6” PVC pipe with a total volume of approximately 7L and a working volume of 5L. The reactors each had independent pH and dissolved oxygen controls in addition to monitoring temperature. A custom microcontroller interface was designed to control reactor set points, and to view real time sensor output.

Wastewater was obtained from the Stevens Point, Wisconsin municipal wastewater treatment facilitiy. The wastewater was diluted to 1500 mg/L MLSS concentration prior to the study start using city tap water.
