Wastewater treatment modelling: dealing with uncertainties

摘要

This paper serves as a problem statement of the issues surrounding uncertainty in wastewaterntreatment modelling. The paper proposes a structure for identifying the sources of uncertaintynintroduced during each step of an engineering project concerned with model-based design ornoptimisation of a wastewater treatment system. It briefly references the methods currentlynused to evaluate prediction accuracy and uncertainty and discusses the relevance of uncertaintynevaluations in model applications. The paper aims to raise awareness and initiate ancomprehensive discussion among professionals on model prediction accuracy and uncertaintynissues. It also aims to identify future research needs. Ultimately the goal of such a discussionnwould be to generate transparent and objective methods of explicitly evaluating the reliabilitynof model results, before they are implemented in an engineering decision-making context.
