Auditable Automation of Activated Sludge Modeling for Wastewater Treatment Diagnosis Using LLM-Agents

Abstract Wastewater treatment plants (WWTPs) need mechanistic models that explain carbon, nitrogen, and phosphorus transformations under changing operating conditions. Building activated sludge models (ASMs) still depends heavily on expert choices about boundaries, components, an...

Scalable OnlineMachine Learning for Water QualityOptimization and Carbon Source Reduction in Wastewater Treatment Plants

Abstract Effective real-time control of wastewater treatment plants (WWTPs) remains challenging due to highly variable influent conditions, while regulation of external carbon sources (ECS) is critical for sustaining nitrogen removal and meeting increasingly stringent effluent st...
