Object of the course is the description of the systems that, by using characteristic methodologies of an engineer approach, are able to lead to the environmental sustainability of human processes: on the basis of the knowledge of the origin of the phenomena that must be regulated and also of the evaluation of the tools that can be used, the different solutions able to lead to a containment of impact are presented. In particular the intervention technologies for primary waters and wastewater, for residuals treatment, for limitation of emissions are presented. Also different approaches useful for environmental protection are introduced, with reference to the adoption of prevention policies, the use of economic and financial tools, the fixation of rules. The course is a part of a whole formation way, that is directed to evaluate the possibilities for the technological control of the quality of the environment and the right use of the resources, with particular focus on process and plant aspects.

The course is a part of a whole formation pathway, that is aimed to evaluate the possibilities for the technological control of the quality of the environment and the right use of the resources, with a particular focus on process and plant aspects. In addition to theoretical insights, time is dedicated to practical examples that allow the student to realize the concepts learned in experiences of common life and in the context of future professional life. The use of practical examples is also aimed at stimulating reflection on how the adoption of engineering technologies can limit/reduce the impact on the environment of human activities.
On the basis of the learning of the proposed solutions and technologies the student will be able to evaluate the impact load that is originated from a specific human activity, and to fix the instruments that must be adopted for the containment, by considering performances, applicability, project criteria, costs, results. The knowledges that must be acquired are directed to the definition of a multi-disciplinar approach to the establishment of solutions for impact limitation, by evaluating for the different tools that could be considered the best use in a perspective of integrated resolution.
On the basis of the learning of the proposed solutions and technologies the student will be able to evaluate the impact load that is originated from a specific human activity, and to set the instruments that must be adopted for the containment, by considering performances, applicability, project criteria, costs, results. The knowledge that must be acquired are directed to the definition of a multi-disciplinar approach to solutions for impact limitation, by evaluating, for the different tools that could be applied, the best use in a perspective of integrated resolution. Particularly the student will know: - the main laws concerning water, waste and gaseous emissions management and treatment; - pollutants physical and chemical properties and related possible dynamics in the environment; - the main physical, biological and chemical technologies that may be adopted for emissions treatments with related advantages and disadvantages, - some dimensioning technologies and cost-benefit evaluation.
In order to obtain an useful apprehension and a capacity to apply the transmitted information with the required competence, the student must know the necessary operative fundaments, that are at the basis of the technological solutions that are adopted in the different cases. The required knowledge concerns aspects of water chemistry (stoichiometry, equilibria, chemical kinetics) and basical elements of biology that are applied in the operations of biological oxidation; it is also very important the preliminary capacity to define the reactor process aspects and the plants for mass transfer, as these structures are the basis for the construction of most of the technological solutions that are adopted in the pollution treatment.

The course is organized in five modules. I module (20 h) - Economic and normative tools for the realisation of environmental sustainable solutions .Clean technologies, modification of industrial processes, intervention on raw materials and on the employed resources. Physical, biological and chemical processes applied to solid, liquid and gaseous residues. II module (20 h) - Formation of urban solid wastes, prevention, different collection systems, reuse and recycle. Treatment of urban solid wastes: separations, composting, anaerobic digestion, thermal utilisation, landfill Treatment of industrial wastes, valorisation, destruction, segregation . III module (5 h) - Principles for atmospheric emissions limitation, planning solutions, scenarios for modification of processes and plants. IV module (25 h) - Global water cycle. Selection of primary sources, characteristics for water supply. Primary water treatment: aeration, sedimentation, filtration, disinfection, adsorption, chemical treatments. Hypothesis for reuse and recycle for non-drinking water.Treatment of wastewater: physical, physico-chemical, chemical, thermal operations. Generation of residuals and sludges in primary and waste waters. Principles and operating conditions for biological oxidation and nutrients removal. Generation, treatment and final destination for sludges deriving from biological operations V module (10 h)- Advanced water treatments: membranes.
During the presentation of the arguments that constitute the object of the course numerical exemplifications are introduced, in order to explain the principles and the applications of the described systems. To these exercises it is devoted a third of the total time of the course.
The course is structured in: - 50 hours of classroom lessons, aimed at the development of knowledge related to pollutants, emissions according to industrial activities, treatment technologies, applied solutions to practical cases (as described in detail in the program); - 30 hours of group and classroom exercise aimed at stimulating the ability to apply the knowledge acquired in the resolution of practical problems. Numerical exercises will also be presented and the treatment technologies will be discussed to provide students with tools for their selection and critical analysis.
In account of the quite low complexity of the arguments that are introduced during the course, and from the other side by considering the high application meaning and the constant technological evolution of the presented schemes, it doesn’t seem convenient to indicate a specific textbook, able to be a specific reference basis for the exam preparation. In order to know more, for all the presented arguments there is a very large bibliography, with different level of deepening and different treated arguments; this bibliography can be suggested to the students for an higher comprehension or a more extended analysis of the arguments that are introduced during the lessons or the exercises.

Modalità di esame: Prova scritta (in aula); Prova orale facoltativa; Elaborato scritto prodotto in gruppo;
Exam: Written test; Optional oral exam; Group essay;
In order to verify the apprehension of the presented arguments and the capacity to arrive to 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 verify the maturity level that from the student has been obtained. 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 lessons. By means of the oral it is possible to add/decrease until 3 points. The final mark takes into account also the group works performed during the lesson period. An excellent judgement in the group work may add until 2 points to the final mark. Without the existence of the group work 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 the general indications that are introduced.
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.
