PERIOD: MARCH - JUNE
The course provides theoretical and practical aspects of seawater/brackish water desalination technologies. Fundamental thermodynamic and transport processes which govern the creation of fresh water from seawater and brackish ground water will be discussed. The technologies of existing and future desalination systems will be discussed, with a focus on membrane-based separation and thermal separation: technological, economic, and environmental factors which limit the performance or the affordability of these systems will be highlighted. Emerging materials and technologies for desalination will be considered. This course is organized within the framework of the CleanWaterCenter, the interdepartmental center of Politecnico di Torino devoted to research and innovation of water treatment technologies.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam:
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
