Nitrogen is present in many forms in wastewater. Excess nitrate discharged from a wastewater plant can be harmful to both humans and the environment. Nitrate entering drinking water wells can have serious health effects while excess nitrate in water bodies can lead to eutrophication (nutrient enrichment due to human activity) which can create an unfavorable environment for aquatic ecosystems. Biological nutrient removal (BNR) is a process commonly used to remove nitrate from wastewater.
Effective nitrogen removal requires supplemental carbon addition to support denitrification. Real-time monitoring of nitrate concentration allows for carbon addition optimization to maintain nitrogen removal targets and avoid overfeeding to lower costs.
- Optimized supplemental carbon addition
- Meet TN effluent compliance
- Avoid overfeeding
- Lower costs
