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.

Fundamental knowledge of chemistry and physics are compulsory.

Introduction: Organic and inorganic pollutants and related properties. Interaction with soil, water and air. Main pollutants sources (1,5 cfu); Measure units, reaction kinetics, mass balances, concentration balances, energy balances, ideal reactors (1,5 cfu); Water and wastewater treatment (2 cfu) • primary treatments: equalization, separation of coarse solids, sedimentation, flotation; • biological treatments: aerobic fermentation, anaerobic fermentation, suspended and adhered 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): • Characterization and risk analysis • Remediation technologies Applied cases and preliminary dimensioning (2 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.

Material available on the web (portale della didattica): lecture slides, limited portions of reference books; scientific papers as further readings.

Modalità di esame: Prova scritta (in aula); Prova orale facoltativa; Elaborato progettuale in gruppo;

Exam: Written test; Optional oral exam; Group project;

... 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.
