This review emphasizes the significance of formulating control strategies for biological and advanced oxidation process (AOP)-based wastewater treatment systems. The aim is to guarantee that the effluent quality continuously aligns with environmental regulations while operating costs are minimized. It highlights the significance of understanding the dynamic behaviour of the process in developing effective control schemes. The most common process control strategies in wastewater treatment plants (WWTPs) are explained and listed. It is emphasized that the proper control scheme should be selected based on the process dynamic behaviour and control goal. This study further discusses the challenges associated with the control of wastewater treatment processes, including inadequacies in developed models, the limitations of most control strategies to the simulation stage, the imperative requirement for real-time data, and the financial and technical intricacies associated with implementing advanced controller hardware. It is discussed that the necessity of the availability of real-time data to achieve reliable control can be achieved by implementing proper, accurate hardware sensors in suitable locations of the process or by developing and implementing soft sensors. This study recommends further investigation on available actuators and the criteria for choosing the most appropriate one to achieve robust and reliable control in WWTPs, especially for biological and AOP-based treatment approaches.

“…Respirometry rate represents the digesting bacteria OUR due to their metabolic processes. OUR can be monitored using online respirometer probes [143]. However, to have a more effective control, knowing the MLSS value of the AS and employing it to determine the specific oxygen uptake rate (SOUR) is required.…”

Sequencing Batch Reactors (SBR) are a popular choice for wastewater treatment. Proponents of the technology note that SBRs do not require secondary clarifiers, can be adapted to biological nutrient removal and have a smaller overall footprint than conventional activated sludge treatment.The authors of this paper would like to suggest a further advantage to SBR technology -that it is the most controllable treatment option. They argue that respirometry is the best technique for controlling an SBR. Based on several years' experience in developing online respirometers, the algorithms for SBR control are now available for implementation in the form of a new Smart Activated Sludge (SAS) controller. This paper presents the fundamental principles behind respirometric control of an SBR and insight into how this can be applied to a full-scale SBR.
