Abstract:
|
|
Disinfection of effluent from water reclamation facilities (WRFs) is required to decrease the disease risks associated with the discharge of wastewaters containing human pathogens (disease-causing organisms) into receiving waters. These microorganisms are present in large numbers in wastewater effluents, and waterborne disease outbreaks throughout history have been directly attributed to wastewater contaminated drinking water supplies, water-contact recreational waters, and impacted shellfish habitats. The pathogens of greatest concern are enteric (intestinal) bacteria, viruses, and parasites.
Disinfection is an important step in deactivating potentially harmful organisms. This chapter will describe the most commonly used disinfection practices, including UV irradiation, chlorination and subsequent dechlorination, ozonation, and other methods such as the use of bromine chloride, chlorine dioxide, and peracetic acid.
While the understanding of fundamental mechanisms for wastewater disinfection has changed little over the years, applications of the technologies have evolved considerably. This chapter has been revised to include current industry trends associated with post-September 11, 2001, emphasis on security and safety associated with selection of technologies; recent focus on receiving water impacts caused by disinfection byproducts; challenges associated with wet weather treatment applications; and new and evolving technologies.
