Simplified Model for the Activated Sludge System: WWTP Cost Minimization via an Augmented Lagrangian Pattern Search Method

摘要

This paper aims to validate a proposed simplified model of the activated sludge system. A comparison between the classical and simplified models is made. The optimization of the operational and investment costs in order to achieve the best design is conducted using an augmented Lagrangian pattern search based algorithm. The results are similar in both models and reinforced that the simplified model is a good approach.
