generate large volumes of concentrated
waste, and fail to remove co-contaminants
- all of which threaten the sustainability of
treatment systems.
In response to the growing concerns
with ammonia contamination, EPA
engineer Dr. Darren Lytle developed and
patented a biological treatment system
for the concurrent removal ammonia and
three common co-contaminants - iron,
manganese and arsenic. This technology
was later awarded and transferred to
AdEdge Water Technologies, who began
the work of scaling the system to a point
of practical, municipal application. The
result of this collaboration is NoMonia,
a dual stage biotreatment process that
relies on naturally occurring bacteria in
groundwater to enhance the nitrification
process (the conversion of ammonia to
nitrite and then nitrate). In nature, the
amount of ammonia that can be oxidized
is inherently limited by oxygen availability
and its saturation level in water. NoMonia
addresses the oxygen requirement for
waters with high ammonia concentrations
by introducing oxygen to the system to
optimize bacterial activity.
NoMonia functions as a single process
across two distinct but integrated stages.
The first stage is a biological contractor
that introduces oxygen continuously,
allowing for the vast majority of ammonia
removal. The second stage is a biological
filter that concludes ammonia removal and
eliminates oxidized metals and other solids.
The end result is the complete oxidation of
ammonia to nitrate and the conversion of
contaminated groundwater to safe drinking
water. Additionally, biological treatment
with NoMonia is chemical free, produces
no waste stream, and can be integrated
into existing treatment systems.

Palo, Iowa: A case study
Prior to 2008, the town of Palo, Iowa
had no centralized water or treatment
center. However, heavy flooding that year
prompted the need to install infrastructure
that would provide potable drinking water
to Palo citizens. The high ammonia and iron
concentrations in the Palo groundwater
(3.3 and 0.82 mg/L respectively) made it
the perfect test site for the original EPA
patented technology. Consequently, an
EPA pilot system was installed to field
test the effectiveness of the system. The
