Prerequisites
Completing the course "Environmental Engineering" is recommended before taking this course.
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
- Analyse, evaluate, design and operate the systems or processes, equipment and installations used in chemical engineering in accordance with certain requirements, standards and specifications following the principles of sustainable development.
- Develop personal work habits.
- Develop thinking habits.
- Objectively compare and select different technical options for chemical processes.
- Participate in the organisation and planning of companies.
- 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
- Adapt to unforeseen situations.
- Apply matter and energy balance to typical continuous and discontinuous environmental engineering systems.
- Apply unitary operations to environmental processes.
- Critically evaluate the work done.
- Describe and explain in depth the technologies, tools and techniques applied to the treatment of industrial and urban solid waste and the production of sources of renewable energy
- Design and calculate engineering solutions to environmental problems.
- Develop a capacity for analysis, synthesis and prospection.
- Objectively distinguish different alternatives in solid and industrial waste treatment plants and in the processes of obtaining renewable energies
- Organise and schedule the management of an environmental problem, an installation or an environmental service.
- Work with common equipment used in the treatment of environmental problems.
Content
This course is divided in nine parts:
1. Introduction to the problem of wastewater
2. Water purification
3. Pipes and pumping
4. Pretreatment
5. Primary treatment
6. Secondary treatment
7. Sludge management
8. Treatment of odours
9. Tertiary treatment and potabilization
Methodology
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

Assessment
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
