• Summary
Who Is NuSystems?
NuSystems is located in Bay City, Michigan serving customers
throughout the Midwest. We perform our services in Wastewater
Treatment, Industrial Processing, Institutional Applications and
the Paper Industries. We support Environmental Management
Systems (EMS), and quality programs such as ISO 14000 and
Good Manufacturing Practices (GMP).
We provide life science chemistry based solutions for municipal
and industrial applications from air scrubbers to waste treatment
processes. Our technology focus is pH neutral chemistries that
work to eliminate odors, reduce COD/BOD, breakdown
Suspended Solids, Fats, Oils and Grease which provides a more
treatable waste for downstream processes.

What happens in a lagoon..
Aerobic Respiration – The Role of Oxygen
Municipal Waste + Bacteria + Oxygen  CO2 + Bacteria
Two pounds oxygen per pound BOD
Compressed air or electric aerators.
WWTP budgets are typically 30% for
power.
Lagoons use less power and more time.
Oxygen Sources in Municipal Lagoons
• Biological (algae)
• Mechanical (aerators, diffusers)
• Atmospheric Diffusion (wind)
Algae
Oxygen
Photosynthesis and Respiration
Algae + CO2 + Sunlight
More Algae + Oxygen + Carbonate
• Biomass increases nutrient uptake ( P, N ).
• Bacterial respiration decreases organic waste (C)
• ReNew allows algae to produce more oxygen.

Value Proposition
• Near future (present to 6 months)
– Reduced Odor
– Reduced Power (if aerated)
– Reduced Chemical Addition
– Improved D.O.
• Long term (6 months to 1 year)
– Reduced Sludge Layer
– Reduced Green House Gas Emissions
– Steady Improvement in Effluent Quality
Clarification of water allows algae to produce more oxygen
Case Study Data
Data and Methodology: In order to understand the affects of candidate treatment
technologies we must safely collect surface and subsurface water quality data before and after
treatment. There are numerous variables that can affect the data like rain, sunlight,
temperature, volume flow rate changes, and fluctuations in organic load. The equipment shown
here is used to collect, Dissolved Oxygen, Oxidation Reduction Potential, Total Suspended
Solids, pH, Conductivity, and chlorophyll content. This information is used to better understand
the performance of the untreated lagoon, and to make decisions on the viability of various
treatment options.

Village of  – NuSystems Lagoon Program Results
Primary issues regarding the wastewater lagoons:
•
Sludge: Sludge removal cost for cells 1&2 was approximately $300,000.00 plus.
The NuSystems Lagoon Treatment Program reduced the sludge 25% in the first
year. This is a reduction of approximately $75,000.00 in removal costs.
•
H2O/Odor: Community odor complaints averaged five or six per year. For the years
ending 2011 and 2012, there were 0 complaints.
•
Aeration costs: Two aerators were in operation with a cost of $1,500.00 per
month, excluding man hours for maintenance and repair. Three months after the
beginning of the NuSystems technology implementation, the aerators were
decommissioned and the dissolved oxygen numbers increased.

Village of  – NuSystems Lagoon Program Results
Primary issues regarding the wastewater lagoons:
•
Sludge: Sludge removal for the Village of  was to be 25% greater
than average due to high metal content within the sludge. The sludge blanket has
been reduced 10% annually since 2009 with the NuSystems Lagoon technology.
•
Odor Control: Before the NuSystems technology was implemented, 
was experiencing extensive odor issues on cell #1 and the main lift station in town.
After a week of implementation, all odors were gone. There was also no odor at
turn over time in the spring.

Summary
• Hard data in Lagoon enhancement has been scarce
• Claims for performance improvements have been many
• Operators have been justifiably skeptical
• Data gathering is expensive and necessarily site specific
• Best data sets combine laboratory, controlled field and
actual operating data from a variety of Lagoon
operations
• Decision to accept an enhancement program must be
based on scientific data, field experience and value to
the community
