acid, to produce TTHMs or HAA5s. The chlorine dioxide does not produce
these two DBPs above. However, the chlorine dixoide does produce its unique
byproduct, chlorite, which is in the EPA primary drinking water standard.
In the past 10 years, chlorite was found to be an effective inhibitor for
ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) growth
. It has been used for controlling nitrification in
