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 comprehension and a capacity to apply the transmitted information with the required competence, the student must know the necessary operative fundamentals, that are at the basis of the technological solutions that may be adopted in the different cases. The required knowledges concern 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.

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 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.

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

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 .

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.

Exam: Compulsory oral exam; Paper-based written test with video surveillance of the teaching staff; Group project;

Compulsory oral exam; Paper-based written test with video surveillance of the teaching staff; Group projects; In order to verify the apprehension of the teached arguments and the capacity to arrive to practical applications, a traditional exam in written form is used. In the written exam one exercise is proposed to students. The written exam lasts 75 minutes and the maximum mark is 30. No texts are allowed during the written exam for consulting. The oral is compulsory and consists in one question on the topics examined during the lessons, the maximum mark is 30. An average of the written exam mark and of the oral mark will be done. The final mark takes into account also the group works performed during the lesson period. A public presentation of the group work by all the students is foreseen. 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
