Single-Course English 10 ECTS

Environmental Processes

Overall Course Objectives

The overall aim of the course is to:
Get a quantitative understanding of important physical,chemical and microbiological processes that control:
– Concentrations of compounds in the environment
– Concentrations of compounds in environmental engineering reactors/technical installations
Create the foundation for more advanced courses within water technology and water pollution
Illustrate how the engineer works with practical issues.

Learning Objectives

  • Calculate concentrations in chemical equilibrium systems with acids and bases, chemical precipitation and complex formation reactions
  • Carry out equilibrium calculations in two-phase gas/liquid systems
  • Calculate concentrations in systems with sorption and ion exchange
  • Explain the content of specifications of water quality and be able to describe the concentrations of important components in water
  • Set up mass balances for natural and technical systems and be able to calculate characteristic times
  • Conduct calculations – based on mass balances – of transport of water components controlled by advection, diffusion and dispersion, including the transport in porous media
  • Carry out tracer experiments and interpret the data in relation to basic reactor parameters
  • Carry out calculations of reaction kinetics in simple batch reactors
  • Calculate concentrations in reactors combining reaction kinetics and mass transport (reactor hydraulics)
  • Conduct experiments in the laboratory
  • Communicate aims, theory, methods, results, discissions and conclusions in a technical report
  • Carry out an engineering analysis of the concentrations of compounds in a relatively complex system consisting of processes in nature (surface water and groundwater) and in a waterworks

Course Content

Mass balances,chemical equilibria,acids and bases, carbonate chemistry, chemical precipitation, complex formation,phase distributions in two- and three-phase systems (water, solid gas),redox systems,ion exchange,sorption. Flow in porous systems. Soil properties. Emphasis is put on learning the theoretical principles through practice-oriented activities: project work and lab. exercises. In addition, emphasis is put on communication of results in the form of well-structured reports.

Recommended prerequisites

12000, A basic course in chemistry at the Institute for Chemistry DTU og Excel

Teaching Method

Lectures, exercises, 3 laboratory exercises and project work in groups.



The course is a prerequisite for the majority of the courses offered by DTU Environment. As a consequence, it should be taken early during the studies.
