الملخص	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.	Biogas production modeling is a quantitative method to predict methane and carbon dioxide generation from anaerobic digestion of organic residues (wastewater sludge, food waste, agricultural manure, slaughterhouse waste). Developed from microbial kinetics and thermodynamics, these models account for substrate composition, microbial consortia (acetogens, methanogens), process conditions (temperature, pH, retention time), and inhibition factors (ammonia, volatile fatty acids). Biogas modeling supports reactor design, energy recovery planning, and operational optimization.
