خلاصه	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.	Wastewater treatment design is the comprehensive planning and engineering of municipal and industrial treatment plants to remove contaminants (organic matter, nutrients, pathogens, trace organics) from domestic and industrial wastewater. Modern treatment plants integrate preliminary screening, primary settlement, secondary biological treatment (activated sludge, trickling filters, lagoons), advanced treatment (membrane filtration, oxidation, absorption), sludge processing, and biosolids management. The design balances regulatory compliance, treatment performance, energy consumption, land use, and capital and operational cost.
