An activated sludge system accomplishes an enhanced biological purification of wastewater, and is the most frequently used system to purify such.

The purification of wastewaters are dynamical systems, operating under important and uncontrolled variations of concentration and composition of the polluting substances. Mathematical models are essential for describing, predicting, and controlling these processes.

The aim of this article is to describe the modeling and simulation of activated sludge processes, using COMSOL Multiphysics.
