Multiobjective performance assessment of wastewater

Multiobjective performance assessment of operational strategies at wastewater treatment plants (WWTPs) is a challenging task. The holistic perspective applied to evaluation of modern WWTPs, including not only effluent quality but also resource efficiency and recovery, global environmental impact and operational cost calls for assessment methods including both on and offsite effects.

Aeration Control with Gain Scheduling sciencedirect

Within process control one common example is scheduling of PIDcontroller parameters to handle a nonlinear process. An example of a version of gain scheduling in wastewater treatment is Gerksic et al. (2006). Käppala WWTP was the case study in this work where gain scheduling is investigated by simulations and in fullscale experiments.
