Abstract Details

2007, MS, University of Cincinnati, Engineering : Environmental Engineering.
The objective of this project was to evaluate methods for possibly overcoming limitations of methanol addition for full-scale facilities that have limited available anoxic solids retention time (SRT). There is considerable uncertainty associated with the denitrification potential of aerobically grown methylophilic bacteria and its effect on full-scale plant design/operation. It was hypothesized that methanol addition under aerobic conditions (bleeding a small amount of methanol into the aerobic zone of a BNR process) could alleviate anoxic SRT limitations in a full-scale plant by increasing the active methylotrophic biomass content in the process. It is critical to understand denitrification kinetics under these conditions. To perform this research, 3.5 liter sequencing batch reactors were operated to observe methanol acclimation. Data was collected by monitoring the SBRs to determine the specific denitrification rate (SDNR). Once the SBRs stabilized, High Food to Microorganism tests were performed to determine the maximum anoxic growth rate of the methanol denitrifiers.
