Dynamic Simulation of Wastewater Treatment Plants
Simulation-based investigation to reduce nitrogen and phosphorous emissions
Mathematical modelling and dynamic simulation of municipal wastewater treatment plants, in particular activated sludge systems, have gained increasing attention for design and optimization of wastewater treatment plants within the last years. Standardized mathematical models have been implemented in several simulation platforms. These platforms provide basic tool-kits for physical-chemical process units, biochemical processes, activated sludge and biofilm technologies, sludge treatment and energy consumption estimates. Mathematical modeling of municipal wastewater treatment plants is thus a multidisciplinary effort combining physical/chemical reactiosn with microbiology, and transport phenomena.
The overall aim of such simulations lays in generating a better understand of the physicochemical as well as biochemical processes in technical systems, and to optimize performance and control. Especially, optimization of nutrient removal may benefit from dynamic simulations.
Objectives of the project
The objectives of the study are:
(1) Implementation of a municipal wastewater treatment plant schema with one/two software packages.
(2) Optimization of the treatment plant with special focus on nutrient removal (nitrogen, phosphorous)
(3) Comparison of the results obtained with respective software, defining pros and cons of the each
The software tools available will be Aquasim 2.1g, Simba#, Biowin 5.0 und SUMO.
Two IREP student(s) can work on this project.
