Learning Assessment

Learning Assessment Procedures

Final exam: oral discussion of Exercises / Project and other topicsof the course (the project paper (Word and Excel formats) must be sent to the teacher one week before the exam).

There is also an "in itinere" test. Passing the "in itinere" test allows students to take the oral exam mentioned above excluding the topics for which they have already had a positive evaluation that will contribute to the final grade. However, they have the opportunity to take the exam on the whole program even in the case in which a positive evaluation of the ongoing test is examined.

Exams can also be carried out electronically should the conditions require it, request it.

Examples of frequently asked questions and / or exercises

Reactor Sizing.

Coagulation.

Advanced oxidation processes,

Desalination.

Biological treatments.

Disinfection and control of DBPs.

Potable reuse.

Contaminants of emerging concern (CEC).
