Depletion of existing groundwater sources forced Tampa Bay
(Fla.) Water to use alternative sources for drinking water supply.
To help determine the effect of alternate source water quality
on distribution system water quality, a kinetic model for nitrification
was developed using Monod kinetics. The model was
tested on finished waters that had been produced from groundwater,
surface water, and saline sources and then distributed to
pilot distribution systems.
Many US utilities have implemented chloramination for residual
and disinfection by-product control. Nitrification has been reported
by some of these water providers using chloramines in their distribution
systems. The steady-state plug-flow model described here
predicted ammonia, nitrite, and nitrate in the presence of chloramines
as well as active ammonia-oxidizing bacterial biomass and
nitrite-oxidizing bacterial biomass.
This model is one of the first developed specifically for drinking
water distribution systems and from data from a large-scale
field study. It provides the water community with a tool previously
unavailable, i.e., a fundamental model for predicting nitrification
in chloraminated distribution systems. By using the model to
estimate nitrification, water providers can take a proactive
approach to controlling nitrification in their systems. Includes 43 references, 4 tables, 10 figures.
