Description:
This chapter provides an integrated overview of nitrification causes and control in chloraminated drinking water distribution systems, leading to an in-depth discussion of nitrification microbiology, monitoring, prevention, response, and engineering improvements in subsequent manual chapters. Chapter 4 revision authors, Routt and Wahman, gratefully acknowledge the substantial work and contribution of Andrzej Wilczak, as author the original M56 Chapter 4, and through his contributions and review for this revised chapter. The chloramine chemistry and conditions or factors causing or controlling nitrification are divided into the following interrelated categories for discussion and overview here: (1) Chloramine chemistry ~ demand and decay reactions, (2) Water Quality Factors ~ sources, treatment, and system (3) Distribution system Factors ~ operations, maintenance, and design (configuration). Overview of nitrification-related regulatory information is provided in chapter 1, nitrification in drinking water and waste water treatment and distribution in chapters 2 and 3, microbiology of nitrification in chapters 5 and 6, and detailed examples of nitrification monitoring, prevention, and control options in chapters 7 – 10.
