The Full-Scale Implementation of an Innovative (Supplemental)
Across the United States, high levels of ammonia in drinking water
sources can be found. Although ammonia in water does not pose
a direct health concern, ammonia nitrification can cause a number
of issues and reduce the effectiveness of some treatment processes.
An innovative biological ammonia-removal drinking water
treatment process was developed and, after the success of a pilot
study, a full-scale treatment system using the process was built in
a small Iowa community. The treatment plant included a unique
aeration contactor design that is able to consistently reduce
ammonia from 3.3 mg of nitrogen/L to nearly nondetectable after
a biofilm acclimation period. Close system monitoring was
performed to avoid excess nitrite release during acclimation, and
phosphate was added to enhance biological activity on the basis
of pilot study findings. The treatment system is robust, reliable,
and relatively simple to operate. The operations and effectiveness
of the treatment plant were documented in the study.
