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.
- Apply scientific method to systems in which chemical, physical or biological transformations are produced both on a microscopic and macroscopic scale.
- Assume the values of professional responsibility and ethics required in chemical engineering.
- Demonstrate knowledge of the different reaction, separation and processing operations for materials, and transport and circulation of fluids involved in the industrial processes of chemical engineering.
- Demonstrate understanding of the main concepts for controlling chemical engineering processes.
- Develop personal attitude.
- 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.
- 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
- Apply PID controls of temperature and level to typical environmental engineering processes.
- Apply matter and energy balance to typical continuous and discontinuous environmental engineering systems.
- Apply numerical methods to resolve typical empirical cases in environmental engineering.
- Apply the basics of chemical engineering to the treatment of urban and industrial solid waste and the obtainment of sources of renewable energy.
- Apply unitary operations to environmental processes.
- Calculate losses by friction in conduction in environmental technologies.
- Critically analyse the results of experiments and the overall work done in processes related with the treatment of environmental problems.
- 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.
- Generate innovative and competitive proposals in professional activity.
- Manage information by critically incorporating the innovations of one's professional field and analyse future trends.
- Monitor the progress of a chemical reaction in environmental processes.
- 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
Visit to WWTP
The proposed teaching methodology and the examinations may undergo some modifications depending on the attendance restrictions imposed by the health authorities
About 15 minutes of the course will be allowed to the students so they can fill the teachers and course assessment forms.
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
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
