Recent regulatory trends from federal and state agencies suggest that many wastewater treatment plants will be required to remove total nitrogen (TN) and/or total phosphorus (TP) in upcoming years. In many instances, the required effluent nutrient concentrations are low (<3 mg N/L; <0.1 mg P/L) and often exceed a technologies best achievable performance. This proceeding is derived from a WERF Nutrient Challenge compendium that focuses on tertiary denitrification processes. Typically, these processes are the last barrier in a treatment train. As a result, they present special challenges when attempting to meet low TN/TP levels. The designs are largely based on empirical experience and performance is variable. The objective of this study is to provide a baseline state of the industry document on key design/operational issues and identify research gaps and challenges in meeting low TN/TP levels.
