Financial
The Project continues to be well under budget for both the Maintenance and Chemical
Rebateable accounts. Oxygen expenses have started to impact the Chemical Rebate
Account and will continue to pressure our budget, however, we are under budget for now.
Notable Expenses:
1- Oxygen for Noland: $27,488
2- Oxygen for Noland: $27,979.70
3- Pump parts: $4891.36

Jet Aeration
In May, the newly installed jet aeration system
was tested and started in Aeration Basin 1 of the
Noland WWTF. The new units replaced two older
surface mount aerators that were at the end of their
service life due to age and the lack of available
parts. Once the new units were tested, Aeration
Basin 1 was brought online to meet the demands of
high fiows and summer temperatures. So far, the jet
aerators are producing 2.0ppm dissolved oxygen
during daytime fiows while using 58 amps of power
each. By comparison, the older surface mount
aerators installed in the corresponding positions on
Aeration Basin 2 are using an average of 96 amps of
power to produce equivalent amounts of dissolved oxygen. As a result, the new jet
aerators are using 40% less power to aerate basin 1 than the older units in basin 2.
Inframark staff will continue to monitor the new
aerators and the basin. Of particular interest will be
the jet aerators ability to keep the mixed liquor
suspended inside the basin, without having
biosolids accumulate in areas were the turbulence
and fiow velocity are lower. So far, there is no
evidence of solids settling in the basin.

Maintenance
UV Disinfection
One of the focal points during the month of May was restoring the
capability of the UV disinfection system at the Westside WWTF.
Over the last year, a number of the bulbs had failed, reducing the
effectiveness of the UV system. Inframark was able to locate an
alternate supplier for compatible bulbs, reducing the cost by over
30%. With the new bulbs installed, fecal coliform counts for the
facility have dropped and we are much better able to deal with
the high storm related fiows that have pushed through the plant
over the past few months.
Laser Alignment
During the start up of Aeration Basin 1, care was
taken to align the motors and gearboxes of the
surface aerators that moved to accommodate the
jet aeration system. Proper alignment greatly
increases the service life of equipment by reducing
the strain on the output bearing of the electric
motor and the input bearings of the gearbox. At
the end of the alignment process, the motor and
gearbox were within flve thousandths of an inch
(0.005) of true. By comparison, the motor when
initially bolted to gearbox was over three hundred eighty thousandths (0.380) out of
alignment which would have resulted in extreme wear and early failure of both the electric
motor and gearbox.

Pretreatment
For the month of May, staff have collected several discrete composite samples from the
effluent of Con Agra as part of our industrial surveillance program. In addition, Inframark
met with Wolfspeed to facilitate removing them from the Categorical Discharge
classiflcation. Lastly, revenue is somewhat high this month due to the unusually high
surcharges for Tyson Foods.

Fertilizer production at the BMS facility has increased
due to warmer temperatures and the implementation
of the new dewatering polymers at Noland and
Westside. Currently, two drying houses per week are
being processed through the belt dryer, achieving
greater than 92% solids on a single pass.

Noteworthy Activity
During May 2025, Inframark
hosted four (4) tours of the
Westside WWTF. The groups
included children from both
middle school and high school
and totaled over 200 students.

Woolsey Wet Prairie
Inframark staff have conducted several surveys at Woolsey this month and applied
herbicide to non native species found at the site. Below are the areas we've covered:
Surveys conducted in Buffer zones and E1-5
Herbicide Applied:
2 gallons glyphosate (2%) applied in E3
2 gallon glyphosate (2%) applied in East Buffer Zone
2 gallons glyphosate (2%) applied in E2
1 gallon glyphosate (2%) applied in E1
Species targeted were Fescue, Yellow Rocket, and clover.
