Environmental remediation
Module Natural purification techniques and water reuse

Academic Year 2022/2023 - Teacher: Salvatore BARBAGALLO

Expected Learning Outcomes

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. The student will acquire skills on the design of natural wastewater treatment systems.

Course Structure

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.

As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.

Detailed Course Content
