“…WWTPs are considered a censorious response to the growing public health concerns associated with urban sprawl and industrialization, which have led to the contamination of natural water bodies [14,15]. Traditional energy consumption patterns in WWTPs have historically been characterized by high levels of electricity and thermal energy use, mainly due to the intensive mechanical and biological processes for aeration in the activated sludge process, pumping systems, and equipment required for water treatment through the removal of solids and other contaminants to meet regulatory standards [16,17]. Research on municipal wastewater treatment plants has revealed that up to 66% of the energy used in activated sludge treatment facilities is consumed by sludge pumping and aeration, as seen in Figure 1.…”

“…Increasingly, mathematical computer-based models are being utilized for wastewater treatment processes to predict various technological options, facilitating the identification of optimal solutions such as the aforementioned NO 2 shunt method and reductions in aeration costs. Aeration constitutes the most energy-intensive process in wastewater treatment plants [Gu et al, 2023], often exceeding 50% of total energy consumption [Drewnowski et al, 2019]. Most current aeration systems rely on measuring oxygen concentrations in the nitrification tank for control.…”
