Biological Nutrient Removal (BNR)


Enhanced Biological Phosphorous Removal (EBPR) is capable of achieving soluble phosphate concentrations under 0.1 mg/L. However, many facilities struggle to routinely achieve soluble phosphate concentrations under 1.0 mg/L. This research report will aid municipal wastewater treatment plants in more efficiently and cost effectively removing phosphorus through EBPR processes.

The report includes detailed analysis of routine water quality and operating data, field testing observations, and special studies conducted over the course of the project to evaluate the variability of EBPR, factors influencing EBPR performance, and the relationship between EBPR and the presence of glycogen accumulating organisms.
