Main analytical methods for the determination of pollutants in the samples under examination
To acquire knowledge on the issues of wastewater natural treatment. The student will acquire knowledge about the regulatory limits for discharge and reuse of wastewater and the most innovative systems of extensive natural wastewater treatment.
Frontal lessons and exercises (in classroom, seminars and technical visits)
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it.
