This paper addresses the mathematical modelling of wastewater treatment plants (WWTPs) extending the traditional WWTP models by considering not only the actual treatment processes but also the associated measurement, actuation and control equipment. Thus, a three-layer, componentbased modelling architecture replicating a complete WWTP is presented: (1) the “mass” layer, i.e. WWTP’s unit processes; (2) the “instrumentation & actuation” layer, i.e. sensors and actuators; and (3) the “automation & control” layer, i.e., control devices. Important aspects for assessing controllers’ performance such as signal noise, signal delay, faults, sampling frequency or energy consumption have been also considered in order to mimic the real conditions at which controllers usually operate. Based on this, a first implementation integrating two well known simulation platforms (Matlab/Simulink and WEST/Tornado) has been carried out.
