A Tale of Two Plants: Same City, Same Process, Different Effluent TN and TP

Abstract

The City of Durham, North Carolina, owns and operates two 20 million gallon per day (mgd) wastewater treatment facilities, the North and South Durham Water Reclamation Facilities (NDWRF and SDWRF). Both plants receive similar influents and utilize a 5-stage Bardenpho biological nutrient removal (BNR) process with a 23-hour detention time at design flow. Both facilities produce treated effluent with total nitrogen (TN) concentrations of less than 7 mg/L (without supplemental carbon) and total phosphorus (TP) concentrations of less than 0.5 mg/L. However, the NDWRF has produced a higher quality effluent (TN
