Publisher's Synopsis
Nitrification is a common operational problem experienced by utilities that chloraminate, arising from the associated addition and release of ammonia that can support the growth of AOB. Due to the slow growth of AOB, monitoring for nitrification events has focused on surrogate parameters instead of direct AOB enumeration. These surrogates can be influenced by factors other than nitrification and detectable changes in their concentrations can lag behind increases in the AOB population.
