This course provides a thorough introduction to ultraviolet (UV) light technology used to disinfect drinking water. The course includes a description of basic chemical and physical principles, the components of UV equipment, and performance monitoring for UV facilities.

You will learn how the mechanism of disinfection by UV light differs considerably from the mechanisms of chemical disinfectants such as chlorine and ozone. You’ll learn how UV light causes microbial inactivation, how microorganisms can repair the damage, and you’ll be introduced to the concept of UV dose-response. The material covers many aspects for consideration when implementing a UV disinfection system.

The course will be beneficial for a student with basic knowledge of water treatment design and is interested in learning about how UV disinfection is now being applied as a disinfection alternative. It is also an excellent overview for those professionals working in the field of water treatment.
