Nitrification potential curves: a new strategy for nitrification prevention

Journal AWWA, 2005
In this article, nitrification potential curves are introduced as a possible operational strategy to prevent nitrification in chloraminated distribution systems. Nitrification potential curves are constructed based on the parameters that define growth and inactivation kinetics of ammoniaoxidizing bacteria in environments that contain chloramine and ...

Simulated distribution nitrification: Nitrification Index evaluation and viable AOB

Journal AWWA, 2013
Lab‐scale reactors were used to evaluate the impact of simultaneously increasing temporal influent monochloramine (NH2Cl) concentrations (0.0 to 3.2 mg/L Cl2) and chlorine‐to‐nitrogen mass ratios (0:1 to 3.2:1) on nitrification, allowing evaluation of the recently proposed Nitrification Index (NI) for chloraminated drinking water distribution system ...

Symbiotic Aspects of Nitrification

Nature, 1946
IN an interesting article on the symbiosis between myxobacteria and nitrifying bacteria, Imsenecki1 describes an observation which he made during his studies on the biology of myxobacteria, when he was able to isolate from a culture of Nitrosomonas, grown in its elective medium, a heterotrophic organism which he has named Sorangium symbioticum.

Nitrification in Inland Waters

2011
Over the past 15 years, the use of modern molecular biological approaches has radically advanced our understanding of nitrification processes. With chapters contributed by leading experts in the field, Nitrification fully reviews all the latest research findings on microbes involved in conventional aerobic nitrification, anaerobic ammonia oxidation ...

Autotrophic Nitrification in Bacteria

1990
Publisher Summary This chapter highlights the physiology of autotrophic ammonia- and nitrite-oxidizing bacteria. Several aspects of the physiology of nitrifiers of relevance to their growth and activity in natural environments are considered. The chapter describes the basic features of the biochemistry of ammonia and nitrite oxidation and discusses ...
