2. Objectives and learning outcomes
2.1 Objectives
The aim of the course is to introduce the complex processes taking place during drinking water and wastewater treatment technologies:
  • Technological lines suitable for the purification of drinking water, especially in the case of deep water bases, with special regard to the removal of iron, manganese, arsenic and ammonium ions
  • Water quality changes in the water distribution system
  • Analysis of case studies (technological deficiencies, water quality deterioration in the water distribution system)
  • Possible technologies for wastewater treatment for large, medium and small wastewater treatment plants
  • Activated sludge methods, biofilm methods, case studies, sludge treatment, biogas utilization, energy balance of wastewater treatment plants
2.2 Learning outcomes
