Aeration is typically the largest energy consumer in activated sludge systems, making efficient process control a key priority for wastewater treatment plants. At the same time, new regulations like the Urban Wastewater Treatment Directive of the European Union increase the pressure on facilities to meet stricter nutrient removal requirements, reduce greenhouse gas emissions, and operate more sustainably.
In this webinar, discover how continuous ammonium (NH₄⁺) monitoring can help optimize biological treatment processes and enable more efficient aeration control. Learn why ammonium is the most valuable indicator for nitrification control, how modern online monitoring technologies deliver reliable real-time data, and how that data can be used to improve process stability while reducing energy consumption.
Through practical application examples and a live demonstration of WTW's online ammonium monitoring solutions, you'll gain a clear understanding of how ammonium-based aeration control supports operational efficiency, regulatory compliance, and sustainability goals.
What you'll learn
- Understanding the relationship between ammonium concentration, nitrification control, aeration demand, effluent quality and sustainability goals
- Comparison of online NH₄ measurement technologies, including practical applications and a live product demonstration
- Identify the most effective measurement locations for ammonium monitoring within activated sludge processes
- Distinguish between time-based, dissolved oxygen (DO)-based, and NH₄-based aeration control strategies and understand their respective applications
- Real-world examples of operational improvements, energy savings, and successful implementation of online monitoring systems
