Learning objectives

Divided in two parts biology and chemistry. Natural scientific basics get across to join the extension courses of water usage concern. The part of biology contains the biological coherences of water quality and wastewater treatment. Organism in waters and in wastewater treatment will be presented, cell structures and metabolism of organism illustrated. Significant processes such as respiration, fermentation, nitrification, denitrification, bio-logical phosphate elimination will be exemplified basically and related to the degradability in waters/wastewater. The part of chemistry contains the basic terms and definitions of water chemistry as there are oxidation and reduction processes, acid-based-equilibrium, carbonation and precipitation.


Part biology

  • Systematics and morphology of organisms
  • Eco-systems and their biocoenosis
  • Mass and power balances
  • Basic principles of biological wastewater treatment
  • Aerobic and anaerobic metabolism, nitrification, denitrification, biological phosphate elimination

Part chemistry

  • Atoms and elements, chemical bond and chemical reactions
  • Water and its properties, pH-value, acid, base, buffer
  • Thermodynamical basics and reaction kinetics
  • Electrochemical potential, redox potential, oxidation and reduction processes
  • Precipitation, flocculation and further chemical-physical wastewater treatment processes
