The objective is to determine if a point of diminishing returns is reached where the sustainability impacts of increased levels of nutrient removal outweigh the benefits of better water quality.\nFive different hypothetical treatment trains at a nominal 10 mgd flow were developed to meet treatment targets that ranged from cBOD mode (Level 1) to four different nutrient removal targets. The nutrient removal targets ranged from 8 mg N/L; 1 mg P/L (Level 2) to the most stringent at <2 mg N/L; <[url] mg P/L (Level 5). Given that sustainability is a broad term, the industry-accepte.
