Teaching language

Portuguese

Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

It is intended that the student:
-knows the unit operations and processes for water treatment (surface and groundwater);
-knows how to design the treatment organs;
-knows the main variables for the process control;
-knows how to monitor and operate water treatment plants, for its optimization.

Syllabus

1. Water and applied environmental legislation
European and National strategic action plans. Legislation on water quality for different uses. Environmental
quality standards. Public concession regimens for drinking water
2. General information on water supply systems
Water catchment. Adduction. Storage
3. Unit Operations and Processes in Water Treatment Systems
Conventional water treatment systems
3.1. Coagulation-flocculation
Jar-test. Agitation and mixing equipments
3.2. Sedimentation and Settling
Types of settlers
3.3. Granular Filtration
Types and control of filters used in water treatment.
3.4. Activated carbon adsorption
Application forms.
3.5. Membrane systems
Types, geometries and operation
3.6. Softening and conditioning
Reagents dose
3.7. Disinfection
Chemical disinfectants agents
4. Drinking water distribution systems:
Distribution and management of the water supply network. Leak detection.

Practical component: lab of each water treatment step

Demonstration of the syllabus coherence with the UC intended learning outcomes

In this unit students learn the processes and unit operations for the treatment of water (surface and
groundwater). The unit allows the competences in:
- Implementation, execution and monitoring of water treatment units projects;
- Operation and management of water treatment plants and distribution systems (monitoring, control,optimization).

Teaching methodologies

Theoretical and practical classes: participatory, interactive training. In laboratory classes, students perform experiments that will allow a better understanding of the studied matters regarding main operations, their parameters and monitoring.
There is a study visit to a Water Treatment Plant, within the discipline.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

The course has a strong laboratory component, intending that the student, in addition to knowing the unit operations involved in water treatment, knows in practice how to monitoring, control and optimize.
It is also intended to strengthen the ‘hands on’ skills and to develop team work competences.

Assessment methodologies and evidences

Theoretical grade weighs 70% of final classification and is obtained by the weighed arithmetic average of marks obtained in written tests (minimum of 2) or by the final exam classification. The lab grade weighs 30% of the final grade. The lab grade is evaluated based on written questionnaires and reports, an oral discussion of them and student performance on lab. The score of the tests cannot be less than 8 values, while the exam score cannot be less than 9,5. Lab grade cannot be less than 9,5.
The final grade must be greater or equal to 10 after rounding.
