|Outline and Purpose of the Course||Water supply is introduced as one of the urban supplies, from the point of technologies of protection of life. Role of water supply system and risk management of water quality as well as water purification technologies are targeted in class. Class is conducted through thinking together.|
|Course Goals||To understand basics of water purification technologies, role of water supply system in water cycles in the basin, and management of health risk through risk management of water supply.|
|Schedule and Contents||
Overview (1 time)
Concept of sanitary engineering, a study on protection of life, and water supply engineering as an example of the sanitary engineering are introduced. Goal of the class is also stated.
Watershed management and water supply system (1 time)
Role of water supply system in water cycle of watershed is introduced. Concept of protection of water source, and integrated river basin management and its significance are discussed.
Over view of water supply system (1 time)
Total water supply system from catchment to consumer taps and outline of topics covered in the class are introduced.
Water purification process (4 times)
Basics of water purification processes are turbidity removal and disinfection. Mechanisms of slow and rapid sand filtration systems, disinfection and pathogens in water are introduced. Formation of disinfection byproducts, harmful compounds such as carcinogenicity, after disinfection is also stated in details.
Advanced water purification process (2 times)
Water qualities of source water are widely varied. It is difficult to meet many types of needs of consumers for drinking water by conventional water purification processes. Advanced water purification processes such as ozonation, activated carbon treatment, membrane treatment and their significance are introduced.
Water quality management (4 times)
There are microbial and chemical risks in drinking water. Safe levels should be maintained as drinking water are discussed. Concepts and methodologies to set drinking water quality standards, and future prospects of water quality management are stated.
Achievement confirmation (1 time)
Achievement of learning is confirmed.
|Evaluation Methods and Policy||
Grade is evaluated by reports, a paper test, and attendance.
Breakdown: sum of the results of the reports and the paper test (60%), attendance (40%).
