Dynamic Influent Generator for Alternative Wastewater Management with Urine Source Separation

Abstract

The simulation of wastewater treatment plants allows obtaining predictive results when one needs to understand, evaluate, optimize or design a plant. However, one of the bottlenecks of the simulation feasibility is to obtain reliable and dynamic influent data. This difficulty is even more important when alternative scenarios are considered, such as source-separated streams. The present paper offers an influent generator to simulate scenarios where urine is separated at source and at a user-specified level of retention. The proposed tool contains several blocks to include different contribution (household and industrial wastewater) and, due to its flexibility, allows the user to easily modify the parameters to fit other case studies. The tool allowed generating dynamic, long-term and predictive data for both urine and wastewater streams. Also, the extensive set of state variables ensured the generation of influents for different modeling platforms.
