Prerequisites
None
Objectives and Contextualisation
The main objective of the course is that the student is able to integrate the previous knowledge of chemical
engineering and environmental engineering to design the most common operating units in the processes of
wastewater treatment. In addition, the student must acquire a critical spirit to be able to assess the different
alternatives that exist in these treatments and to know how to propose the best option under different
scenarios.
Competences
- Communication
- Develop personal work habits.
- Develop thinking habits.
- Show an understanding of the role of chemical engineering in the prevention and resolution of environmental and energy problems, in accordance with the principles of sustainable development.
- Understand and apply the basic principles on which chemical engineering is founded, and more precisely: balances of matter, energy and thermodynamic momentum, phase equilibrium and kinetic chemical equilibrium of the physical processes of matter, energy and momentum transfer, and kinetics of chemical reactions
Learning Outcomes
- Analyse and evaluate processes in observance of sustainability criteria.
- Apply chemical engineering to the prevention of environmental and energy problems in accordance with the principles of sustainable development and applied to the different production processes of the main inorganic and organic products in the different sectors of industrial chemistry.
- Apply environmental and technological risk the evaluation procedures.
- Apply matter and energy balance to typical continuous and discontinuous environmental engineering systems.
- Communicate efficiently, orally and in writing, knowledge, results and skills, both professionally and to non-expert audiences.
- Develop scientific thinking.
- Enumerate and describe the social factors involved in environmental solutions.
- Identify the applicable environmental legislation on a local, regional and global scale.
- Propose a logical sequence of technologies applicable to the resolution of an environmental problem.
- Work autonomously.

Theory classes. The basic theoretical concepts for the subsequent practical development are introduced in an
orderly and concise manner.
Classes of problems. A series of problems is selected from the collection of each theme. The resolution step
by step of the most representative problems is shown and the resolution scheme of other problems is
presented. Resolution of problems by the students.
Seminars 1) Sludge line of a WWTP. 2) Disinfection processes
Visit to WWTP
Note: 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 |
|---|---|---|---|---|
| Group work. WWTP elements design | 30 | 2 | 0.08 | 4 |
| Partial exam 1. Design of waste water purification processes | 35 | 2 | 0.08 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 |
| Partial exam 2. Design of drinking water production systems | 35 | 2 | 0.08 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 |
| Recuperation exam | 70 | 4 | 0.16 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 |
The evaluation will consist of two parts:
Two partial examinations (70%: 35% each partial) that can include a part of theory and one of problems. A
minimum mark of 3.5 is needed in each one of the partial exams. Otherwise, it will be necessary to recover the
partial suspended in the recovery exam.
Written work that will have to be presented orally in which some of the main units of a sewage treatment plant
(30%) will be designed.
To participate in the recovery exam the students must have been previously evaluated in a set of activities
whose weight equals to a minimum of two thirds of the total grade of the subject
