Mathematical Model of a Collecting and Wastewater Treatment Integrated System

This paper addresses the mathematical model of an integrated system composed of a sewer network and a wastewater treatment plant (WWTP) that serves a city with a population of 250,000 inhabitants. The mathematical model also contains an adaptation interface between the sewer network and the WWTP. The BSM Sewer- Matlab / Simulink software package was used for the sewer network model. ASM2d model developed by the International Wastewater Association (IWA) in SIMBA development environment was used to model the plant. For the coupling of the two models, a conversion system was created between the components of the sewer network effluent and those of the influent of the WWTP. Numerical simulations of the integrated system mathematical model were performed considering an influent specific to five collecting areas from the urban area mentioned above.
