IER offers a proprietary
super-oxygenation technology which is designed to convert anaerobic
effluent streams to a fully aerobic environment. This technology,
trademarked as Gener-Ox™ was installed at the above facility in April
2009 and the result was an immediate and full conversion of the
entire 7.5 mile transport system from an anaerobic, H2S-producing
environment to a totally aerobic, non-sulfur reducing environment.
Effluent water being discharged into the pressurized line was treated
with high concentrations of fully dissolved oxygen while being
transported to the land application network of crop circles. The
resulting benefit has been all odors have been eliminated, zero H2S
has been detected and the land application points and previous
corrosion issues from H2SO4 have been greatly
reduced. An additional benefit has been the reduction of digester
effluent COD levels by 12%, from 583 mg/liter at the digester effluent
point to 510 mg/liter at the end of the force main. All of this
is achieved without the requirement for any chemical feed while only
utilizing mother nature’s oxygen supply. The only costs
that are associated with the Gener-Ox™ system are the installation and
utility costs which are required to operate the system. In the case of
this processor, the resulting electrical consumption associated with
the operation of the system involves a 15 HP centrifugal feed pump and
a 20 HP compressor. Together at full load conditions they result in a
monthly operational cost of ~ $1000.00 based on electrical costs of
brief, the IER’s Gener-Ox™ system gave this client:
dissolved oxygen residual has been maintained at the most distant
application point which is 7.5 miles from the point of initial
were reduced to non-detectable within hours of Gener-Ox™ startup.
- Gas phase Hydrogen
Sulfide (H2S) has been totally eliminated.
- Reduction in corrosion
from acid formation within pumps, wet-well and irrigation components.
- COD/BOD levels were
lowered by 12% (This reduction accomplished even considering the low
COD residual present in the digester effluent).
- Operations and
maintenance costs reduced to a small fraction of the never ending
chemical addition costs, allowing for an accelerated ROI.
