Specific course objectives

The course is composed of two modules. The FIRST MODULE (Wastewater and drinking water treatment plant design) deals with the design criteria of technologies for water and wastewater treatment, with the use of different evaluation approaches. The SECOND MODULE (Advanced technologies in water and wastewater treatment) deals with innovative techniques for water and wastewater treatment, in order to provide the tools for a critical assessment of new processes; appropriate technologies for environmental management in developing countries will be analyzed.

Course programme

MODULE 1 (Wastewater and drinking water treatment plant design) – WASTEWATER TREATMENT

• Definition of design data (wastewater flow, load of pollutants) by means statistical evaluations, surveys, analytical campaigns.
• Design of processes for urban wastewater treatment (water line and sludge line).
• Plant layout.
• Preparation of design drawings; examples of wastewater treatment plant project.

MODULE 1 (Wastewater and drinking water treatment plant design) – DRINKING WATER TREATMENT

• Definition of design data (wastewater flow, water characteristics) by means statistical evaluations, surveys, analytical campaigns
• Design criteria of processes for surface water treatment.
• Plant layout.
• Examples of a water treatment project.
• Technical tour to a water treatment plant.

MODULE 2 (Advanced technologies in water and wastewater treatment) – WASTEWATER TREATMENT

• Membrane Biological Reactor (MBR).
• Sequencing Batch Reactor (SBR).
• Biological treatment using attached-growth biomass.
• Advanced chemical oxidation processes and their integration with biological processes.
• Fate of hazardous compounds (mass balance).
• Technologies for minimization of sludge production.
• Performance evaluation of wastewater treatment plants (conventional and innovative techniques).
• Management and structural upgrading.

MODULE 2 (Advanced technologies in water and wastewater treatment) – DRINKING WATER TREATMENT

• Technologies for drinking water treatment.
• Design criteria for drinking water treatment plants.

MODULE 2 (Advanced technologies in water and wastewater treatment) – APPROPRIATE TECHNOLOGIES FOR ENVIRONMENTAL MANAGEMENT IN DEVELOPING COUNTRIES

• Environmental issues in emerging markets.
• Requirements for sanitary-environmental engineering systems.
• Issues in design and implementation of facilities.

Testing and exams

MODULE 1: The exam consists of a written test and an oral exam. The written exam could be performed with two written tests (average score greater than or equal to 18/30), planned in the middle and the end of the course; as alternative to the two written tests, student can perform a single test on the whole program of the course. MODULE 2: The exam consists of a written test and an oral exam. The students have to pass the written test with 18/30 at least, and then they will take the oral exam. The final score is the average of the scores in the two modules.
