The course is focused on suspended and biofilm monitoring, modeling and control in environmental applications based on the knowledge of stoichiometry, kinetics, thermodynamics and models conceptual structure of bioprocesses. This knowledge is applied during a guided simulation of a wastewater treatment train.

Learning Objectives
To understand the ecological function of microbes in natural ecosystems and their metabolic potential in environmental engineering.
To acquire knowledge on basic mathematical modeling tools for the simulation of contaminated matrices treatment processes based on microbial communities application.
To learn how toapply mathematical modelling tools in the design, monitoring and control of wastewater treatment facilities.
To acquire learning ability on natural selection-based microbial community mechanisms and to apply it in microbial community engineering.
Prerequisites
Basic knowledge of physical chemical and biological processes of waste and wastewater
During the lectures the teacher will provide a software and the information needed to simulate a case study of a wastewater treatment train. A report on the case study will be required in order to get access to the oral exam. During the oral exam the modelling case study will be discussed together with the other topics of the course and the final score will depend on the quality of both the report and the oral exam. It will be necessary to be registered for the oral exam of “Modelling and control of microbial ecosystems” in order to receive a score in the online system.
During the oral examination the following learning objectives will be considered:
- the knowledge of the ecological function of microbes in natural ecosystems and their metabolic potential in environmental engineering;
- knowledge on basic mathematical modelling tools for the simulation of contaminated matrices treatment processes based on microbial communities application.
- the capability of applying mathematical modelling tools in the design, monitoring and control of wastewater treatment facilities.
- the knowledge of natural selection-based microbial community mechanisms and the capabilities of applying it in microbial community engineering.
