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

  1. Apply matter and energy balance to typical continuous and discontinuous environmental engineering systems.
  2. Apply numerical methods to resolve typical empirical cases in environmental engineering.
  3. Apply PID controls of temperature and level to typical environmental engineering processes.
  4. Apply the basics of chemical engineering to the treatment of urban and industrial solid waste and the obtainment of sources of renewable energy.
  5. Apply unitary operations to environmental processes.
  6. Calculate losses by friction in conduction in environmental technologies.
  7. Critically analyse the results of experiments and the overall work done in processes related with the treatment of environmental problems.
  8. Critically evaluate the work done.
  9. 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
  10. Design and calculate engineering solutions to environmental problems.
  11. Develop a capacity for analysis, synthesis and prospection.
  12. Generate innovative and competitive proposals in professional activity.
  13. Manage information by critically incorporating the innovations of one's professional field and analyse future trends.
  14. Monitor the progress of a chemical reaction in environmental processes.
  15. Objectively distinguish different alternatives in solid and industrial waste treatment plants and in the processes of obtaining renewable energies
  16. Organise and schedule the management of an environmental problem, an installation or an environmental service.
  17. Work with common equipment used in the treatment of environmental problems.

This subject does not contemplate the single assessment system.

The evaluation will consist of two parts:
Two written 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 assay that will have to be presented orally in which some of the main units of a sewage treatment plant
(30%) will be designed. The use of AI is allowed for the completion of written assay.


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.

Awarding an honors grade is the decision of the teaching staff responsible for the subject. The HG can only be awarded to students who have obtained a final grade equal to or greater than 9.00. Up to 5% of the total number of students enrolled can be awarded.

A student will be considered non-assessable (NA) if he/she has not presented a set of activities whose weight is equivalent to a minimum of two thirds of the total grade of the subject.

Without prejudice to other disciplinary measures that may be deemed appropriate, irregularities committed by the student that may lead to a variation in the grade of an evaluation act will be graded with a zero. Therefore, copying, plagiarism, cheating, allowing copying, unauthorized use of AI (e.g., Copilot, ChatGPT or equivalents), etc. in any of the evaluation activities will imply failing it with a zero. Assessment activities graded in this way and by this procedure will not be recoverable. If it is necessary to pass any of these assessment activities to pass the subject, this subject will be suspended directly, without the opportunity to recover it in the same year.

Repeating students may be exempt from carrying outthe written assay, maintaining their grade, provided that it is higher than 5.

The review of exams and assignments will be carried out in person, on a date agreed with the teaching staff.
