Content

The course consists of the following modules: Unit 1. Stoichiometry and energetics of microbial growth.

Stoichiometric conservation laws, red-ox reactions in microbiology, bioenergetics, assimilation and dissimilation, lumped parameters, the concept of chemical and biological oxygen demand, important parameters in Environmental Technology. Water quality and quantitative methods for chemical and physical characterization.

Unit 2: Process analysis

Reactors, Mass balances, Tranport and reactions, The steady state approximation.

Unit 3: Microbial conversion processes and kinetics

The cellular yield, cellular growth stoichiometry, COD balances and BOD. Population versus individual cell growth, substrate specific growth kinetics, Monod kinetics, Multi- substrate kinetics, Inhibition kinetics, Environmental factors and kinetics. Maintenance. Loss of bacterial cells: Cell death and endogenous respiration.

Unit 4: Bioprocess analysis

Continuous stirred tank reactors, Batch and Feed Batch reactors, Biomass retention, Activated Sludge Process, Biofilm reactors.

Learning outcome

Following this course, students will be able to combine transport and conversion mechanisms in systems analysis of natural and technical aquatic systems. Students are to establish the macrostoichiometry of cellular growth and decay, understand and apply microbial kinetics, perform elementary bioprocess analysis of batch and continuous mixed cultures. Furthermore, students will have detailed knowledge of chemical and physical characterization of natural- and wastewaters, and be able to perform these in laboratory and field settings.

Required prerequisite knowledge

General requirements for the MSc in Environmental Engineering.

Recommended prerequisites

Basic chemistry as required for admission to MSc Environmental Engineering, including elementary microbiology (in case this is missing MLJ520 Environmental Microbiology should be taken the same semester).

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
