The main objective of this course is introduction and application of quantitative methods and estimations used in bioprocess analysis, water and wastewater treatment technology and water quality analysis.

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.

Contents

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.

Required prerequisite knowledge

Bachelor's degree according to admission requirements for MSc in Environmental Engineering or Biological Chemistry.

Recommended previous knowledge

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).
