Abstract:
The Upflow Anaerobic Sludge Blanket (UASB) team has been designing, fabricating, and testing a gravity-powered wastewater treatment system for communities seeking an alternative to releasing waste directly into streams and rivers. A reactor with pulsed flow was installed at the Ithaca Area Wastewater Treatment Facility (IAWWTF) in Fall 2019, and sludge granules were added to initiate organic decomposition. The Spring 2020 subteam began monitoring pH, biogas accumulation, and sludge blanket height on a regular basis, and implemented a system to control reactor temperature. When the reactor completes its startup phase, the subteam will begin monitoring its performance with Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) tests.
