Water Chlorination and Chloramination Practices and Principles (M20): AWWA Manual of Practice (Manual of Water Supply Practices)

A complete information resource on the uses of chlorine and chloramines in municipal water treatment. The manual focuses on chemical properties, disinfection mechanisms, feed rates, handling, storage, and safety. Recent developments in equipment, disinfection strategies, and techniques to minimize the formation of disinfection by-products is also covered in detail This publication is the second edition of the American Water Works Association (AWWA) Manual M20; the original manual was titled "Water Chlorination." This manual provides information on chlorination and chloramination practices for the disinfection of drinking water. It does not cover the use of chlorine as an oxidant or as a disinfectant for pipeline and appurtenances. Topics covered include: history of chlorination and chloramination; properties of chlorination chemicals; chlorination water chemistry and disinfection mechanisms; handling, storage, feed equipment of chlorine and ammonia systems; chlorine and ammonia safety; chlorine/chloramine disinfection strategies; dechlorination; CT values for inactivation of Giardia and viruses by free chlorine and other disinfectants; chlorine residual test methods, and disinfection (chlorination) of facilities. "Disinfection of drinking water is a vital component of the water treatment and delivery system, and the protection of public health is the primary function of drinking water purveyors. It is a great challenge to provide microbiologically safe water and at the same time control disinfectant by-product production. AWWA Manual M20, Water Chlorination/Chloramination Practices and Principles, provides information on two common disinfection methods - chlorination and chloramination - for the disinfection of drinking water."--BOOK JACKET
