Disinfection is an important step in ensuring that water is safe to drink. Water systems add disinfectants to destroy microorganisms that can cause disease in humans. The Surface Water Treatment Rule requires public water systems to disinfect water obtained from surface water supplies or groundwater sources under the influence of surface water. Primary methods of disinfection are chlorination, chloramines, ozone, and ultraviolet light.
This 2-hour interactive online course presents the basics of each type of disinfection system and the advantages and disadvantages of each system. The material is taken from Technical Briefs published by the National Drinking Water Clearinghouse.
There is a test included at the end of this course.
