Base Knowledge
Knowledge about chemical reactions in solution, namely acid-base, oxidation-reduction, complexation and precipitation reactions.
Knowledge about metabolism of biomolecule and energetic conversion. Aerobic and anaeóbic process
Knowledge of some pratical exercices about volume, flow rates, degradation or removal percentage … etc
Teaching Methodologies
In order to achieve the proposed objectives and confer the competences defined for the curricular unit, lectures will be given on the presentation of theoretical contents, complemented by problem solving and discussion of application situations in concrete cases.
Laboratory protocols for evaluating the quality of an effluent will also be carried out and a final analysis report will be prepared.
Learning Results
1. Describe the environmental impacts caused by the discharge of waste, produced by different human activities, into soil and water resources. Evaluate the possibility of its biological treatment.
2. Describe the operating principles of the different types of biological treatment (aerobic and anaerobic), the main factors that influence its functioning and the control parameters of process.
3. Know the applicable legal provisions.
4. To know the role of biotechnology in various fields of action for a more sustainable development.
5. To perform the analytical methodology of some physical-chemical parameters of evaluation of the quality of an effluent, in order to evaluate the operating regime and the efficiency of a treatment system.
