Low DO, High Performance: Optimizing BNR with Online Sensors at Warren WWTF
Join us at WEFTEC booth #1221 for a case study presentation on how Warren, Rhode Island’s wastewater treatment facility achieved remarkable energy savings while optimizing nitrogen removal.
By implementing a low-DO control strategy, Warren WWTF significantly reduced summer blower energy use by 47% —all while consistently meeting a stringent effluent total nitrogen limit of <3 mg/L. Using real-time DO and nitrate measurements to fine-tune aerobic SRT and internal recycle rates, operators successfully lowered DO setpoints to as little as 0.2 mg/L without sacrificing water quality.
This presentation will highlight:
- Best practices for online sensor placement in BNR systems
- Strategies for low-DO control and process optimization
- Practical insights for balancing energy efficiency with compliance reliability
Whether you’re an operator, engineer, or plant manager, you’ll walk away with actionable guidance to reduce energy costs and improve performance in seasonal BNR operations.
