Ing - Civ (Mag.)(ord. 270) - MI (489) INGEGNERIA PER L'AMBIENTE E IL TERRITORIO - ENVIRONMENTAL AND LAND PLANNING ENGINEERING*AZZZZ099296 - WATER AND WASTEWATER TREATMENT TECHNOLOGIES

Obiettivi dell'insegnamento

In the field of Environmental Engineering, this specific course aims at providing the fundamental knowledge to

1) interpret analyses of water and wastewater, by understading the meaning of the analytes and their importance related to pollution of water resources and to the characterization of analytical parameters nedded to design water and wastewater treatment unit operations;

2) outline the main features of treatment unit operations, both for water supply and wastewater tratment plants;

3) outline the proper treatment train to produce safe drinking water from surface water and underground water and to treat polluted wastewater 

4) design, model and operate biological degradation processes, including the treatment and management of the residues produced by the processes.

 


Risultati di apprendimento attesi

Using the terminology and the nomenclature of the Dublin Descriptors (DD), adter passing the exam, the student:

• knows the fundamental principles, theories and concepts of chemical, physical and biological processes for treating water and wastewater (DD1: Knowledge and comprehension)

is able to apply knowledge to specific problems related to water and wastewater treatment (DD2: Ability to apply knowledge and comprehension)

is able to autonomously use and explain the meaning of factual knowledge (terminology, classification, methods, technologies) in the relevant topics of potabilization of water, treatment of wastewater and management of the residues originated from the treatment  (DD3: Making judgments)


Argomenti trattati

The course focuses mainly on water and wastewater treatment process design and operation, and covers the following topics:

1. Water and wastewater characteristics

2. Description and design criteria of primary sedimentation in rectangular, circular and lamella settling tanks

3. Description and design criteria of biological treatment for the removal of biodegradable compounds

4. Modelling the activated sludge process: stoichiometry and biological kinetics; simplified steady-state activated sludge model

5. Aeration and oxygenation capacity: theoretical aspects; clean water and “in process” tests;

6. Other biological processes (fixed-biomass processes, membrane bioreactors)

7. Water treatment for drinking and industrial water supply

8. Sludge treatment and management (production and characteristics; biological stabilization; thickening, conditioning and dewatering; final disposal options.

During Classworks, numerical exercises will deal with:

- Calculation of design flow rates, daily and peak loads;
- Process design of: primary settling, activated sludge process for carbonaceous BOD and nitrogen removal
- Basic design of aeration systems and criteria for testing under operating conditions
- Sludge treatment operations


Prerequisiti

Students are required to know the fundamentals of Mathematics, Chemistry and Physics


Modalità di valutazione

The exam can be passed through a WRITTEN test based on BOTH computational exercises and open text questions.

During the examination the student should prove to be able to

- understand the implications on design of treatment processes of given water or wastewater characteristics

- apply the principles of chemical, physical and biological processes for water and wastewater treatment processes

- size treatment units such as primary settling tanks, biological reactors, secondary settling tanks, aeration systems for biological reactors, anaerobic digesters.
