How Much Nitrogen can this Plant Remove?
In July 2006, an upgrade to the Bucklin Point wastewater treatment facility (WWTF) became fully operational. The project included modifying the plant's existing aeration tanks to the Modified Ludzack-Ettinger (MLE) process, targeting an effluent total nitrogen concentration of 8 mg/L. In response to regulatory requirements, a study was completed in 2007 to evaluate the process performance of the upgraded plant and to determine if the process could be optimized to achieve an average monthly effluent total nitrogen concentration of 5 mg/L. The evaluation consisted of a review of process performance and development of a process simulation model to use as a tool for evaluating performance under differing conditions of flow, load, and operation. The study determined that the MLE process at the Bucklin Point WWTF is not capable of achieving an average monthly effluent total nitrogen concentration of 5 mg/L and that capital modifications would be required to meet that treatment goal.
