Learning outcomes

Students achieve general expertise about dimensioning, management and functional testing of wastewater treatment plants together with main rules of solid waste management. At the end of the course the student may evaluate and control the effects of hydraulic sanitary works and natural system applied to the improvement of water volumes. Course contents

Course contents

A good expertise and understanding of base subject taught of first years should be gained. Mandatory requirements are on imposed but it’s important that the student has taken care of Hydraulics and Chemistry courses. Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.

SANITARY AND ENVIRONMENTAL ENGINEERING

Preface: Sanitary and Environmental Engineering: Hygiene and facility.

Part 1) Wastewater: Cycles and balance in natural and waste water. Technical laws. Industrial and domestic water supply. Hygiene Municipal Regulation. Water outfall discipline. Wastewater reuse regulations. Flowrate and characteristics of domestic and industrial wastewater. Treatability in order to use. Water volumes protection and sanitary reclamation plans. Oxygen balance in lakes and rivers. Eutrophic assessment and water quality in rivers, lakes, and transition volumes.

Part 2) Urban wastewater treatment: Kinetics and biochemistry of bacterial and algal biomass. Growth and death in suspended and biomasses. Full-scale domestic wastewater treatment plant. Choice and location. Equalization. Raw and fine screens. Sand removal. Primary sedimentation. Biodegradability and biological phases for secondary treatment. Secondary sedimentation. Wastewater disinfection. Treatment and disposal of sludge.

Part 3) Solid waste ad air emissions: Product profile and quantitative characteristics for domestic and industrial solid waste. Optimization of harvest and collecting systems. Landfill design criteria. Calculation, drainage and storage of leachate. Biogas production and landfill collection systems. Treatment of organic fraction. Meteorology and atmospheric pollution. Main pollutants and chemical reactions in atmosphere. Diffused and localized sources. Principles and schemes utilized in dispersion models.

Teaching methods

All subjects developed in room lessons are coupled with applications and practical examples.

During exercise hours are analyzed and discussed different biologic wastewater treatment plant schemes based on suspended biomass.


Assessment methods

Achievements will be assessed by the means of an oral final examination. This is based on an analytical assessment of the "expected learning outcomes" described above.

In order to properly assess such achievement the examination is composed of three questions, each related to one of three main parts of the course program: Wastewater, Urban wastewater treatment, Solid waste ad air emissions.

To obtain a passing grade, students must demonstrate a knowledge of the key concepts of the subject and a comprehensible use of technical language.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject and a good ability for critical application.

Failing grade will be awarded if the student shows knowledge gaps in key-concepts and logic failures in the analysis of the subject.


Teaching tools

Each student receives:

  1. slides and projected files used during room lessons which are previously given by the teacher
  2. a design example of an active sludge based wastewater treatment
  3. an harvest of existing technical laws regarding: water resources collection, outfall regulation, treatment and reuse of wastewater.
