Disinfection of Water and Wastewater

Jim Newton, P.E., DEE

Untreated water used for drinking and especially wastewater contain microorganisms that may cause disease in humans and animals, referred to as pathogens. Disinfection uses a number of chemicals or physical processes to reduce and/or eliminate these pathogens. The disinfection of municipal water and wastewater is an integral part in ensuring the health and safety of the public. There are a wide variety of options that can be used to disinfect drinking water and wastewater, many of these disinfection processes, especially those involving the use of chemicals, present additional health and safety concerns to both employees and the general public. The US EPA developed a guidance manual on disinfection processes. This course is based upon the US EPA document “Alternative Disinfectants and Oxidants Guidance Manual ”, EPA Document No. EPA 815-R-99-014, April 1999.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
