Programma dettagliato e risultati di apprendimento attesi

The course will focus mainly on water and wastewater treatment process operation and biological process modelling. In particular, the course will cover the following topics: man and the water cycle, future of water and wastewater treatment: innovation and sustainability, water and wastewater characterisation; preliminary and primary treatments; biological treatments (suspended and attached growth); respirometric tests; focus on oxygen transfer and aeration; tertiary and polishing treatments; sludge treatment and disposal.

The Course will combine lectures and classwork for a total of about 80 hours.

The topics developed during the Course are the following:

Water and wastewater characteristics;

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

Description and design criteria of biological treatment for BOD removal;

Activated sludge process for nitrogen and phosphorus removal;

Respirometry: theory and technique for elaboration of rbCOD, Yh and bCOD from raw data;

Modelling the activated sludge process: stoichiometry and biological kinetics; dynamic modelling with ASM;

Modelling the activated sludge process: simplified steady-state activated sludge model;

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

Fixed-biomass processes: trickling filters, rotating biological contactors, submerged biofilters, fluidized beds, upflow sludge blanket reactors;

Membrane bioreactors: description and characteristics;

Water treatment for drinking and industrial water supply: turbidity removal and filtration; adsorption, ionic exchange resins; disinfection;

Sludge production and characteristics;

Anaerobic digestion: process theory, stoichiometry and design criteria;

Thickening, conditioning, dewatering and final disposal options;

Example of using commercial tools for process modeling;

Slides of lectures, classworks and laboratory description are given as downloadable pdf files, and can be found at the "Beep" website of the Course (see below)

 

CLASSWORK sessions are ESSENTIAL for passing the examination.

Exercises will include the following topics:

1) Flow rates, daily and peak loads, primary settling, activated sludge process for carbonaceous BOD removal

2) Activated sludge process: design procedure by using a simplified steady - state model

3) Nitrogen removal: basic design of the process

4) Aeration capacity: assessment in clean water tests and under operating conditions

5) Respirometric test elaborations

6) Sludge treatment: Anaerobic digestion of mixed primary and excess activated sludge, conditioning and dewatering.

 

The students should prove to be capable of reporting on the following topics:

a) sampling and characterization of water and wastewater

b) fundamentals about unit operations requested for drinking water treatment, the removal of biodegradable organics and other common pollutants in wastewater (nutrients, metals, suspended solids, pathogens);

c) fundamentals of activated sludge process design, modeling and operation, including the interpretation of respirometric tests and the evaluation of the performance of the aeration equipment;

d) fundamentals about unit operations for the treatment of sludge produced by wastewater treatment.


Note Sulla Modalità di valutazione

 

The EXAM will be a WRITTEN test based on BOTH computational exercises and open text questions. A brief discussion with the student will follow the test.
