Summary This course on water and wastewater treatment shows how to apply physical and chemical methods and techniques to produce drinking water, and how to implement and design different methods and techniques to eliminate organic matter, nitrogen, and phosphorus from wastewater. Content

Water quality

Water resources, raw water composition, drinking water regulations

Principles of drinking water production

Physico-chemical processes, oxidation, disinfection, adsorption processes, membrane technologies, biological processes.

Process combinations for drinking water treatment

Evolution of treatment trains, standard process combinations, water re-use systems

Principles of organic and inorganic pollutants removal from wastewater

Primary, secondary and tertiary treatment, uncoupling the hydraulic and sludge residence time.

Activated sludge and immobilized biomass wastewater treatment plants

Operational principles and process diagrams, structure, biology, process configurations.

Elimination of nutrients

The microbial and chemical processes for the removal of nitrogen and phosphorus from wastewater.

 

 Learning Prerequisites Required courses

ENV-200 Environmental chemistry; ENV-202 Microbiology for engineers; ENV-304 Treatment and valorization of water and waste

 Learning Outcomes By the end of the course, the student must be able to:
  • Interpret data on parameters of water and wastewater
  • Verify the design of a classical wastewater treatment plant
  • Optimize nutrient elimination in a wastewater treatment plant
  • Propose a solution for wastewater treatment
  • Assess / Evaluate quantitatively unit processes for drinking water treatment
  • Propose adequate process combinations for drinking water treatment
  • Link raw water quality with drinking water treatment
 Transversal skills
  • Demonstrate the capacity for critical thinking
  • Access and evaluate appropriate sources of information.
  • Assess one's own level of skill acquisition, and plan their on-going learning goals.
 Teaching methods

Lectures ex cathedra and exercises

 Assessment methods

Two written mid-term exams during the semester (40 % of the final grade) and one final written exam (180 min) during the winter session exam period (60 % of the final grade).
