Activated Sludge Model
The Activated Sludge Model (ASM) is a standardized mathematical framework for simulating biological wastewater treatment processes, developed by the International Association on Water Quality (IAWQ) beginning in 1987. It represents the transport, transformation, and fate of organic matter and nutrients in suspended-growth treatment systems. ASM is widely used to design, optimize, and predict the performance of wastewater treatment plants under varying influent and operational conditions.
