Drinking Water Treatment Engineering


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 four to six students. At the end of each class, the groups present their exercise and its solution.

Evaluation method


The evaluation component of the course. includes 2 tests lasting 50 min., and the exercises completed during classes.

The tests weight 60% in the final grade and the exercises 40%.

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, ...).
