Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


Upon completion, the student should be able to:

  • Describe the most important physical and chemical water, wastewater, sludge, solid waste and waste gas treatment processes [knowledge]
  • Explain the theoretical background of relevant physical and chemical treatment units [knowledge]
  • Choose favorable treatment methods for specific water, waste and gases [knowledge/skill]
  • Design and dimension the most common physical and chemical unit processes [skill]
  • Do simple chemical analyses in the analytical water laboratory and write a report [skill]
  • Have a mind-set for understanding the inter-linkages between water, energy and other resources [identity]

  • valid for whole curriculum period:

    This course gives an introduction into the physical and chemical water, wastewater, sludge, solid waste and waste gas treatment processes. The course is useful for students interested in the operation and planning of municipal and industrial water, wastewater and waste treatment plants.

    Main content: Process principles (types of reactors, mass balances, process kinetics) and treatment processes (screening, sedimentation, flotation, coagulation, mixing, flocculation, filtration, adsorption, ion-exchange, membrane processes, gas transfer, disinfection, oxidation, precipitation).

    Note that there's a chemistry pre-assignment in this course. The study material for this is available under Materials. The exam assignment will be opened two weeks before the course starts.

Assessment Methods and Criteria
  • valid for whole curriculum period:

    Lectures, weekly exercises, plant visit, laboratory project (group work), exams. Assessment of the course is based on the exercises, the laboratory assignment and the exams. Relative weights between the different components are given in the beginning of the course.
