Environmental remediationModule Natural purification techniques and water reuse
Academic Year 2023/2024 - Teacher: FELICIANA LICCIARDELLOExpected 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.
Required Prerequisites
Fundamentals of chemistry, biology, physics, mathematics and hydraulics

Learning Assessment
Learning Assessment Procedures
Students will have to pass a written test and a final oral exam
The written test lasts 2 hours and is valid for 1 academic year.
During the written and oral tests, you may be asked to solve exercises on the topics covered during the course
Verification of learning can also be carried out electronically, if conditions should require it.
The evaluation of the student's preparation will be carried out on the basis of the following criteria: learning ability and details degree of the topics covered, synthesis and exposition skills, and the student's reasoning ability.
Examples of frequently asked questions and / or exercises
Quantitative and qualitative characteristics of wastewater
Design of a treatment wetland
Reuse of treated water in agriculture
