Elixir-Enviro - Biological Nutrient Removal Plants (BNR)

Carbon, nitrogen, and phosphorus are significant nutrients for aquatic life. However, excessive levels of these nutrients pose serious problems. Wastewater treatment facilities must adhere to strict nutrient effluent limits, covering phosphorus, nitrogen, carbon, and various micronutrients commonly found in wastewater. Nutrient-rich wastewater can lead to eutrophication, ammonia toxicity, and nitrate contamination of groundwater. Nutrient removal in wastewater is crucial to reduce oxygen demand in receiving water bodies, protect aquatic ecosystems, prevent eutrophication, and ensure public health.
