Calibrating activated sludge models through hyperparameter optimization: a new framework for wastewater treatment plant simulation

Abstract Traditional calibration of Activated Sludge Models (ASM) is often manual, expert-dependent, and inefficient. This study introduces a hyperparameter optimisation framework using Optuna to automate the calibration of the ASM2d model. Built on Python, the model integrates the Tree-structured P...
