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 the completion, the student should be able to

  • Describe the most important biological water, wastewater, sludge, waste and gas treatment methods [knowledge]
  • Explain biochemical, microbiological and ecological phenomena in biological treatment processes [knowledge]
  • Form the simple mass balances of biological unit processes [knowledge/skill]
  • Identify the critical factors affecting the efficiency of biological treatment processes and describe their control systems [knowledge/skill]

  • Valid 01.08.2020-31.07.2022:

    This course gives an introduction into the biological water, wastewater, sludge, solid waste and waste gas treatment processes. The main focus is on wastewater treatment. The course is useful for students interested in the design and operation of municipal and industrial water, wastewater and waste treatment bioprocesses. Introduction to aerobic, anoxic and anaerobic water and waste treatment processes and their biochemistry, microbiology and ecology (biosorption, metabolic processes, mass and energy balances, biomass composition and yield, optimal process environment, inhibitory effects, acclimatization, adaptation and succession); Types of processes and bioreactors; Process parameters and their optimization; Bioprocess control and bioreactor sizing

  • Applies in this implementation:

    Laboratory work will be organized in small groups (max 6 people) with special safety measures. 

    During Spring 2021 the course lectures and homework support sessions will be organized on-line. The possibility to follow the laboratory work remotely will be proposed, but it is advisable to participate in the lab if possible.

    Laboratory work takes place in the Water lab, Tietotie 1E.
