Water Treatment and Environmental Biotechnology EET2110


The candidate will get an overview of methods to analyze and solve aquatic pollution problems and an understanding of how to select sustainable solutions. In-depth understanding of biogas production, including modeling and laboratory tests, is to be obtained, together with an overview of biological processes available for waste and water treatment.

A candidate who has passed the course will have a learning outcome in the form of acquired knowledge, skills, and general competence, as described below.


The candidate:

  • has a highly specialized knowledge of theory and methods used in water treatment, environmental biotechnology and methane production by anaerobic digestion related to general ecological theory


The candidate:

  • is able to apply adequate methods and techniques in solving water treatment and environmental biotechnology problems
  • is able to work as an individual, as well as in teams, in planning and conduction of experiments and technical water treatment projects
  • is able to work safely in environmental laboratories, in accordance with HES procedures
  • knows how to use computer based tools, especially Aquasim, to solve water treatment problems
  • is able to analyze and solve different types of water related environmental problems and recover resources, especially energy from wastewater, based on fundamental, advanced and specialized knowledge

General competence

The candidate:

  • is able to analyse and compare water and waste handling solutions in an ecological and ethical context
  • masters the terminology used and is able to communicate acquired knowledge in the area water treatment and environmental biotechnology – orally, and in technical report writing
  • is able to discuss - with experts as well as with the general public - technical problems, analyses and conclusions within the area of water treatment and environmental biotechnology


  • Aquatic ecology in natural systems and microbial ecology in bioreactors
  • Water quality parameters and physical, chemical and biological water treatment processes
  • Biological processes: Metabolic functions, kinetics and stoichiometry, activated sludge, biofilm and sludge bed bioreactors
  • Biogas production through anaerobic digestion is studied in depth through mathematical modeling and laboratory experiments

Arbeids- og læringsformer

Lectures, theoretical and experimental exercises are integrated with approximately 1/3 of the time spent on each method. This is combined with a good textbook to achieve knowledge, skills and general competence. The lectures highlight the most relevant course topics, knowledge also given in the textbook and help the students understand the most complicated theories. The theoretical exercises are designed to give the students skills in formulating biological processes in mathematical models, implementing these in a computer based simulations tool and carrying out relevant simulations. Some minor laboratory tasks are given as specified elsewhere to achieve skills in relevant laboratory techniques. A major laboratory exercise carrying out a biological experiment is conducted to obtain skills in operating bioreactors, converting waste into renewable resources and interpreting experimental results. A higher level of comprehension is obtained by modeling, simulating and interpreting the biological experiment. The students will also report the experimental and simulated results, gaining general competence in writing scientific reports, including how to cite and reference sources.


The final test counts 70 % and covers the whole course; laboratory work counts 30 % and is graded based partly on performance in the laboratory (5 %) and mainly on an individual report of the theoretical and experimental exercises carried out in groups (25 %).
Grades A-F are used.
To pass the course, the final test must be passed.

Det tas forbehold om mindre justeringer i planen.
