概要

Abstract

The purpose of this paper was to propose proper sensitivity analysis criteria which can minimize calibration efforts and produce reliable effluent quality predictions. ASM1 and ASM3 parameter sensitivity (in combination with a one-dimensional settling model) was analyzed by various criteria based on the step variation of single parameters (SVM) or random variations of all parameters (RVM), using the IWA Simulation Benchmark (Copp et al. 2002). SVM was not significantly affected by the analysis conditions and it produced reliable ΔEQ values in every case. Moreover, it was the easiest and simplest methodology. Once selected the parameters were estimated with a genetic algorithm. It was concluded that SVM was the best sensitivity analysis criteria for both ASM1 and ASM3 in this case.
