Prerequisites
It is recommended to have completed the subject Environmental Engineering.
Objectives and Contextualisation
The course is an introduction to the treatment and management of urban wastewater and drinking water. At the end of the course, students will be able to understand the operation and to design the main elements of a water treatment plant.
Learning Outcomes
- CM33 (Competence) Undertake a general assessment of the social, economic and environmental impact on industrial activities and facilities.
- CM34 (Competence) Undertake partial environmental projects in the field of technology within a team.
- CM35 (Competence) Predict, using environmental engineering concepts, the potential environmental impact of new technological solutions or products.
- KM43 (Knowledge) Recognise the main concepts and technologies related to water management in natural environments or those modified by human activity.
- SM42 (Skill) Assess the analysis and synthesis strategies related to the environmental implications of industrial processes.
- SM43 (Skill) Extract relevant information from engineering or technological projects related to environmental issues.

Theory classes: Theoretical presentation of the subject's scientific-technical content, which will be accompanied by examples of application of the theoretical concepts.
Problem classes: Solving problems corresponding to the subject. Discussion with the students about the solution strategies and their execution.
Seminars: Theoretical presentation and subsequent discussion with a professional in the field of water management and treatment on topics directly related to the subject matter.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Assessment
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| Delivery of a work group | 20% | 0 | 0 | CM33, CM34, CM35, KM43, SM42, SM43 |
| First exam | 40% | 3 | 0.12 | CM33, CM35, KM43, SM42, SM43 |
| Second exam | 40% | 3 | 0.12 | CM33, CM35, KM43, SM42, SM43 |
The subject consists of the following evaluation activities:
- Two partial exams including theory and exercices (40% each exam)
- Delivery of a group work that consists of the design of the main units of a sewage treatment plant (20%).
The non-participation in any of the evaluation activities will be assessed with a zero.
For a student to pass the subject through continuous assessment it is necessary to obtain a minimum weighted grade of 5 in the global of the subject. To be able to make a weighted average between the delivery of group work and the grade of the partial tests, a minimum average grade of 4 out of 10 of the partial tests will be required with a minimum mark of 2 for each of the partial tests.
If grade 5 is not achevieved globally, the student may undergo a recovery exam. In order to be able to take the make-up exam, students must have participated in assessment activities throughout the course that are equivalent to 2/3 of the final grade. In this case, the delivered work group mark remains unchanged.
For each evaluation activity, a place, date and time of revision will be set. There will not be further revision opportunities for students not attending the revision.
Following UAB regulations, students with a grade of 9.0 or higher in a subject may be qualified by an Honors degree. The number of Honors degrees awarded to students cannot be higher than 5% of the total number of students enrolled in a subject.
A student will be considered non-evaluable (NA) if he/she has neither delivered the work group nor undertaken some of the partial exams or the recovery exam.
Without prejudice to other disciplinary measures, and in accordance with current academic regulations, any irregularities committed by the student that could lead to a variation of the score of an evaluation act will be marked with a zero. Therefore, copying or allowing to copy in an evaluation activity will imply a zero (0).
Students coursing the subject for a second or third year must undergo the above listed evaluation activities.
Unique assessment
Students who have accepted the single assessment modality must take a final synthesis test on the date marked in the exam calendar as the second exam. This test will consist of a theory part and a problem part that will account to 80% of the final mark. To be able to make a weighted average between the group work and the test, a minimum average grade of 4 out of 10 is required for the test. If the final grade does not reach 5, the student has another chance to pass the subject by means of the recovery exam.
