Drinking Water Treatment Engineering
Objectives
Having as a starting point knowledge acquired at the course “Supply water and wastewater systems”, this course allows students to acquire technical skills that guarantee water treatment, regardless of its quality. More specifically, by completing this course the student must have the necessary skills to develop/propose solutions for the treatment or rehabilitation of systems, guaranteeing the quality of drinking water.

Teaching method
This course comprises two classes per week, one theoretical-practical and one practical, summarizing four hours/week. During classes, the theoretical concepts are discussed and students are exposed to different issues related to different scenarios.
The contents are shared with students before classes so that they can actively participate in topics’ discussions.
Exercises involve discussion and problems’ resolution in groups of three to four students. At the end of each class, the groups present their exercise and its solution.
Evaluation method
The assessment component of the C.U. includes one 90-minute test and a piece of work carried out in the first four weeks of classes and presented in the fifth week.
The test has a weighting of 50% in the final grade, the assignment 50%.
Approval in the U.C. implies a minimum attendance of two thirds of the practical classes.
Subject matter
- Development of Engineering skills in the design of conventional water treatment systems;
- Aeration and degassing techniques and their importance in reducing the consumption of chemical reagents;
- Flotation by dissolved air, as an alternative to decantation;
- Adsorption associated with the removal of natural organic matter, metabolites (MIB and Geosmin) and other contaminants present in the water;
- Ion exchange, in water treatment;
- Membrane separation processes (microfiltration, ultrafiltration, nanofiltration, and reverse osmosis), used in water treatment and desalination;
- Design of water treatment systems associated with water with the presence of specific contaminants (arsenic, nitrates, ..) or emerging contaminants (pharmaceutical compounds, pesticides, microplastics, ...).
