Biological Nutrient Removal (BNR) in municipal waste water treatment 2. INTRODUCTION Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water. Nutrient removal continues to be a growing area of focus for wastewater treatment throughout the world. The removal of nitrogen and phosphorus require different nutrient removal processes. To remove nitrogen, the nitrogen is oxidized from ammonia to become nitrate through a process called nitrification. This civil engineering seminar topic gives an insight into Biological nutrient removal in municipal waste water treatment which is a much needed technology. Main problem is the rising concentration of nutrients. Nitrogen and phosphorus are the primary causes of eutrophication. Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water. The rising concentration of harmful nutrient compounds specifically nitrogen and phosphorus in municipal wastewater treatment plant discharge causes cultural eutrophication. Carbon substrate is required by biological nutrient removal (BNR) microorganism, but it is usually insufficient in the influent of many municipal wastewater treatment plants. 31 Optimization of municipal wastewater biological nutrient removal using ASM2d Kevin J. Kennedy and Amy Marie McHarg Abstract: Activated sludge model No. 2d (ASM2d) was calibrated then used to determine optimal recycle rates and basin retention times, with respect to nal N, soluble P (sP) or N plus sP concentrations for Modied Bardenpho (MB). Biological Nutrient Removal in Municipal Wastewater Treatment: New Directions in Sustainability Zhirong Hu1; Dwight Houweling2; and Peter Dold3 Abstract: To control eutrophication in receiving water bodies, biological nutrient removal (BNR) of nitrogen and phosphorus has been widely used in wastewater treatment practice, both for the upgrade of existing wastewater treatment facilities and. processes in four biological nutrient removal (BNR) wastewater treatment plants (WWTPs). It was found that the dissolved organic nitrogen (DON) fraction was as high as 47 of soluble nitrogen (SN) in the lowSN effluent plant, which limited the plants capability to remove nitrogen to very low.
