Objectives
MODULE 1 TREATMENT AND REUSE OF URBAN WASTE WATER

Intended learning outcomes and competences to be acquired
To learn about plant and technological solutions for the treatment and reuse of urban waste water, their design criteria, as well as plant management and control solutions.

Knowledge and comprehension skills.
Acquiring knowledge: on the characteristics of urban waste water, on secondary (biological) and tertiary (biological, chemical, physical and chemical-physical) treatments of urban waste water intended for discharge or reuse, on the reference regulatory framework. Understanding of the process schemes for the purification of urban waste water in relation to the final destination (discharge to the environment or reuse), the environmental compartment where the discharge takes place and the regulatory restrictions in force.

Ability to apply knowledge and understanding.
Knowledge of process schemes for the treatment of urban waste water intended for disposal or reuse. Understanding of the problems related to the design of new sewage treatment plants, the functional verification of existing sewage treatment plants, and the design of solutions for the adaptation of existing plants.

Autonomy of judgement.
Ability to identify the most suitable plant solutions and treatment unit combinations according to the characteristics of the urban wastewater and the treatment objectives (discharge to water body, discharge to soil, discharge to sensitive area, water reuse).

Communication skills.
Presentation and discussion of a project thesis related to the functional verification of an urban waste water treatment plant and to the design of the subsequent adaptation for discharge or reuse. Ability to work in a team.

Ability to learn.
Ability to apply the knowledge acquired during the course to the verification and design of urban waste water treatment plants, according to the final destination (discharge or reuse).

MODULE 2 INDUSTRIAL WASTE WATER TREATMENT AND PURIFICATION

Intended learning outcomes and competences to be acquired
To learn the plant and technological solutions for water and industrial waste water treatment and their design criteria.

Knowledge and understanding.
Acquiring knowledge: on the characteristics of the different water matrices to be treated (industrial waste water, contaminated surface water, contaminated groundwater); on the chemical, chemical-physical and biological processes for treatment for disposal, reuse or drinking water; on the reference regulatory framework. Understanding of the process schemes for the purification of industrial waste water for disposal or reuse, and for the potabilisation of surface and ground water.

Ability to apply knowledge and understanding.
Knowledge of the process schemes for the treatment of industrial waste water intended for disposal or reuse and for drinking water treatment. Understanding of issues related to the functional verification and design of industrial waste water treatment and drinking water treatment plants.

Autonomy of judgement.
Ability to identify the most suitable plant solutions and combinations of treatment units according to the characteristics of the water/wastewater to be treated and the treatment objectives (discharge to sewer, discharge to water body, water reuse, potabilisation).
Prerequisites
BACKGROUND ON BIOLOGICAL PROCESSES (SUSPENDED AND BIOFILM SYSTEMS) FOR WASTEWATER TREATMENT.
Contents
THE COURSE IS DIVIDED INTO TWO MODULES CALLED "URBAN WASTE WATER TREATMENT AND REUSE" (MODULE 1, 60 HOURS) AND "INDUSTRIAL WASTEWATER TREATMENT AND DRINKING WATER TREATMENT" (MODULE 2, 60 HOURS).

MODULE 1
1. WASTEWATER TREATMENT PLANTS (WTPS): DEEPENING OF PLANT, TECHNOLOGY AND PROJECT SOLUTIONS FOR URBAN WASTEWATER TREATMENT (10 HOURS OF THEORY 2 OF EXERCISE).
2. BIOLOGICAL REMOVAL OF NUTRIENTS: DESIGN OF BIOLOGICAL TREATMENTS FOR THE REMOVAL OF NUTRIENTS (NITRIFICATION/DENITRIFICATION) AND RELATED SCHEMES (3 HOURS OF THEORY).
3. INNOVATIVE BIOLOGICAL PROCESSES FOR THE REMOVAL OF CARBON AND NITROGEN: BIOLOGICAL MEMBRANE REACTORS (MBR), MOVING BED BIOFILM REACTORS (MBBR), BIOLOGICAL AERATED FILTERS (BAF), UP-FLOW ANAEROBIC SLUDGE BLANKET REACTORS (UASB), ETC. DESIGN AND VERIFICATION (10 HOURS OF THEORY 5 OF EXERCISE).
4. TERTIARY/ADVANCED TREATMENTS: PROCESSES AND TECHNOLOGIES FOR FILTRATION OF WASTEWATER, INTRODUCTION TO ADSORPTION AND OXIDATION WITH OZONE PROCESSES (7 HOURS OF THEORY).
5. SMALL WTP: ROTATING BIOLOGICAL CONTACTORS (RBC), PHYTOREMEDIATION (CONSTRACTED WETLANDS), IMHOFF TANKS; MULTI-BARRIER SOLUTIONS FOR SMAL WTP, SOLUTIONS FOR ISOLATED USERS (4 HOURS OF THEORY 3 OF EXERCISE).
6. WASTEWATER REUSE: REGULATIONS, TECHNICAL PROBLEMS, PROCESS DIAGRAMS, POSSIBLE SOLUTIONS (5 HOURS OF THEORY).
7. WTP MANAGEMENT: FUNCTIONAL VERIFICATIONS, UPGRADING, PROCESS CONTROL, OPERATIONAL PROBLEMS (3 HOURS OF THEORY).
8. DESIGN CRITERIA AND COSTS (3 HOURS OF THEORY)
9. LABORATORY (5 HOURS)

MODULE 2
1. PHYSICAL, CHEMICAL AND CHEMICAL-PHYSICAL PROCESSES: COAGULATION, PRECIPITATION, AIR STRIPPING, OXIDATION, ADVANCED OXIDATION, DISINFECTION, ION EXCHANGE, ADSORPTION (20 HOURS OF THEORY 2 OF EXERCISE).
2. ADVANCED URBAN WASTEWATER TREATMENTS: EMERGING CONTAMINANTS; WASTEWATER REUSE; POSSIBLE SOLUTIONS FOR ADVANCED TREATMENT; DESIGNING CRITERIA (5 HOURS OF THEORY).
3. INDUSTRIAL WASTEWATER TREATMENT: QUALITY CHARACTERISTICS OF THE MAIN TYPES OF INDUSTRIAL WASTEWATER (AGRO-FOOD, TEXTILE, TANNING ETC.); MULTI-BARRIER SOLUTIONS FOR INDUSTRIAL WASTEWATER TREATMENT; DESIGNING CRITERIA (10 HOURS OF THEORY).
4. PHYSICAL (AIR STRIPPING) AND CHEMICAL (OXIDATION) PROCESSES FOR THE REMOVAL OF NUTRIENTS (2 HOURS OF THEORY 1 OF EXERCISE).
5. DRINKING WATER TREATMENT: RELEVANT REGULATIONS, SURFACE AND GROUND WATER CHARACTERISTICS, CONTROL OF DISINFECTION BY-PRODUCTS, MULTI-BARRIER SOLUTIONS FOR DRINKING WATER TREATMENT, DESIGNING CRITERIA (8 HOURS OF THEORY 2 OF EXERCISE).
6. LABORATORY (10 HOURS)
Teaching Methods
FRONTAL LECTURE, PRACTICE EXERCISES, LABORATORY EXPERIENCE, DESIGN WORKING-GROUP HOMEWORK, TECHNICAL VISITS OF WTP/DWTP. IN PARTICULAR THE CLASS INCLUDES TWO MODULES WITH APPROXIMATELY 4.5 ECTS OF FRONTAL LECTURES, 1 ECTS OF EXERCISES, AND 0.5 ECTS OF LABORATORY/VISIT TO URBAN WTP FOR MODULE 1 AND 4.5 ECTS OF FRONTAL LECTURES, 0.5 ECTS OF EXERCISES, AND 1 ECTS OF LABORATORY/VISIT TO INDUSTRIAL WTP/DWTP FOR MODULE 2. THE DESIGN WORKING GROUP HOMEWORK, TO BE DISCUSSED DURING THE EXAM, IS FOCUSED ON THE DESIGN OF THE UPGRADING OF AN URBAN WTP OR THE DESIGN OF AN INDUSTRIAL WTP OR THE DESIGN OF A DWTP. LABORATORY ACTIVITY INCLUDES EXPERIMENTAL TESTS AND RELATED MEASUREMENTS ACCORDING TO THE TOPICS ADDRESSED DURING THE COURSE. CLASS ATTENDING IS NOT MANDATORY.
Verification of learning
INTERVIEW AND HOMEWORK WILL BE THE TOOLS TO EVALUATE LEARNING SKILLS (TOTAL TIME OF THE EXAM APPROXIMATELY 45 MIN). THE TWO STUDENTS OF THE SAME WORKING GROUP ARE REQUIRED TO PRESENT THE HOMEWORK TOGETHER (DURATION OF THE PRESENTATION 15 MIN) IN THE EXAM SESSION IN WHICH AT LEAST ONE OF THE TWO TAKES ALSO THE SUBSEQUENT ORAL EXAMINATION.THE AIM OF THE EXAM IS TO PROMOTE AND EVALUATE STUDENTS' CAPACITY TO SUCCESSFULLY OPERATE IN WORKING GROUPS (QUALITY OF THE HOMEWORK, SPEAKER SKILLS, ANSWER TO QUESTIONS WILL BE EVALUATED) AS WELL AS TO CHECK BY AN INTERVIEW STUDENT CAPACITY TO FIND EFFECTIVE SOLUTIONS TO THE TREATMENT OF SPECIFIC WATER AND WASTEWATER. THE MINIMUM SCORE IN THE ORAL EXAM REQUIRES BASIC KNOWLEDGE OF CHEMICAL, CHEMICAL-PHYSICAL AND BIOLOGICAL PROCESSES FOR THE TREATMENT OF WATER AND WASTEWATER. THE MAXIMUM SCORE IS ACHIEVED WHEN THE STUDENT DEMONSTRATES AN IN-DEPTH KNOWLEDGE OF THE TOPICS COVERED IN THE COURSE AND THE ABILITY TO PROPOSE SUITABLE DESIGN SOLUTIONS FOR THE TREATMENT OF SPECIFIC WATER AND WASTEWATER. THE FINAL EVALUATION MARK WILL TAKE INTO ACCOUNT BOTH HOMEWORK OPEN EXPLANATION AND DISCUSSION, AND SUBSEQUENT INDIVIDUAL INTERVIEW. TO AWARD THE STUDENT THE HIGHEST GRADE THE LEVEL OF DEEPENING OF THE TOPICS INTRODUCED DURING THE CLASS, CAPACITY AND CLARITY IN THE PRESENTATION AND THE INTERVIEW, CORRELATION CAPACITY BETWEEN DIFFERENT ARGUMENTS AND AUTONOMY OF JUDGMENT WILL BE CONSIDERED.
