Abstract

An integrated pollution-based real-time control (RTC) approach is proposed for a sewer network (SN) integrated with wastewater treatment plants (WWTPs) in a sanitation system (SS) to mitigate the impacts of pollution from combined sewer overflows (CSOs) on ecosystems. To obtain the optimal solution for the SS while considering both quantity and quality dynamics for multiple objectives, model predictive control (MPC) is selected as the optimal control method. To integrate SN and WWTP management, a feedback coordination algorithm is developed. A closed-loop virtual-reality simulator is used to assess the results of the optimal management approach achieved by applying MPC. The Badalona SS (Spain) provides a pilot case study to assess the efficacy and applicability of the proposed approach. A comparison with local rule-based and volume-based control strategies currently in use indicates that the proposed integrated pollution-based RTC approach can reduce the pollutant loads released to the receiving environment. ; The authors wish to acknowledge the support from the European Commission research grant of project LIFE EFFIDRAIN (LIFE14 ENV/ES/000860), from Spanish national project DEOCS (MINECO DPI 2016-76493) and the internal project TWINs from the Spanish State Research Agency through the María de Maeztu Seal of Excellence to IRI (MDM-2016-0656). The authors also thank Aigües de Barcelona for their financial and technical support. Considering the fact that data, models and tools used in this research are confidential or commercial, we refer other researchers to contact SUEZ Spain Group (for access to detailed, simplified models; the Closed-loop Simulation Framework software; and the rain data) and Innovyze (for licenses to InfoWorks ICM).
