The aim of the course is to build the basic knowledge concerning organic and inorganic pollutants and the related possible interaction with the environment due to physical and chemical properties. The main sources of pollutants will be examined too. Applied treatments concerning waste, waters and gaseous emissions will be presented with the objective to increase the environmental sustainability of activities and processes involving environmental and civil engineers.

The students will be able to apply the acquired knowledge to understand and evaluate the criticalities deriving from the interaction between anthropic activities and environmental matrices and to select the proper treatment technologies in order to avoid any environmental damages. He/she will be able to perform preliminary dimensioning concerning waste, wastewater and gaseous emissions plants.

biomass systems;
• tertiary treatments: nitrification, denitrification, dephosphating, adsorption, disinfection, filtration, chemical and membrane treatment.
Gaseous effluents (0.5 cfu):
• particulate removal: cyclones, mechanical filters, electrofilters, washing towers; - gas removal: absorption, adsorption, oxidation, biofiltration; - chemical treatments: catalytic conversion, combustion.
Solid effluents and waste (1,5 cfu):
• material recovery: material recycling, conditioning, leaching;
• energy recovery: incineration; inertization;
• biological processes: composting, anaerobic fermentation.
Polluted soil (1 cfu):

The course is 100 hours long and it is organised as follows: about 70 hours are dedicated to lectures about fundamental and technical knowledges. During lectures students are often involved with questions and exercises carried out individually but discussed with the whole group of students to assess the comprehension of principles and theory. Around 15 hours are dedicated to applied cases that will be presented and discussed all together but will be developed and solved in groups working also outside the class hours. This activity has the task of developing students competence and solving capability of real environmental problems. About 5 hours are dedicated to seminars performed by enteprises working in environmental field and presenting applied cases.

In order to verify the apprehension of the presented topics and the capacity to deal with practical applications, a traditional exam in written and oral form is used. In general to the student in the written exam two main arguments are proposed, and as concerns these arguments some questions concerning theoretical basis for the technologies or possibilities of application are asked in order to check the maturity level that has been obtained by students. The written exam lasts 75 minutes and the maximum mark is 30. The oral is facultative and consists in one question on the topics examined during the lectures. By means of the oral it is possible to add/decrease up to 3 points. The final mark takes into account also the group works performed during the lesson period. An excellent judgement in the group works may add until 2 points to the final mark. Without the existence of the group works it is not possible to give the exam.
The final evaluation is based on the apprehension capacity that has been demonstrated, on the quality of presentation, on the demonstration of the acquired capacity to apply to specific practical cases .
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.

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.
