The intermittent cycle extended aeration system (ICEAS), a modified version of the Sequencing batch reactor (SBR) process, allows continuous wastewater inflow during a single-reactor operation. This system addresses the limitations of the standard SBR process, including the need for sedimentation tanks and sludge return systems and their susceptibility to shock loads. While maintaining simplicity in facility design, the ICEAS process addresses the challenge of achieving continuous inflow and outflow of wastewater. In this study, the performance and critical functions of a full-scale wastewater treatment facility with a capacity of 2,150 m³/day were primarily examined using the improved ICEAS process. The study focused on determining the optimal operating range based on standard parameters in biological reactors, such as MLSS, SRT, DO, sedimentation indices (SV30, SVI, SDI), and advanced treatment ratios (C/N ratio and C/P ratio). The obtained results were applied to the target facility from January 2020 to December 2022. Predictive modeling and operational modes were developed to handle scenarios encountered in real wastewater treatment plants, including fluctuations in influent concentration and flow, rainy weather conditions, and seasonal operations. These measures ensured stable water quality management and compliance with effluent quality regulations.
