Re: Application for Authorization to Construct
Floating Aeration Rotors
West Jefferson Wastewater Treatment Plant
NC Division of Water Resources:
Calvin Green, Alderman
Jerry C. McMillan, Alderman
John K. Reeves, Alderman
Stephen Shoemaker, Alderman
Brett T. Summey, Sr., Alderman
Please accept this letter as the formal request for the Authorization to Construct for the Floating
Aeration Rotors at the West Jefferson Wastewater Treatment Plant, NPDES Permit No.
NC0020451. The project involves the replacement of the existing Orbal Rotors in the outer
basin of the WWTP Oxidation Ditch. The existing rotors do not provide sufficient mixing and
oxygen transfer. Additionally, the pillow block bearings on the existing rotors wear out annually
and have to be replaced at a significant cost. The proposed floating aeration rotors will provide
both better mixing and oxygen transfer without the need for any pillow block bearings.
Additionally, the floating aeration rotors will operate at a reduced Hp, thereby saving electrical
costs. The Town of West Jefferson proposes to directly purchase the new rotors and hire a local
contractor to install them. The overall cost of the project is estimated to be approximately
$125,000. The Town will use fiend balance to build this project. It is expected that the project
will begin in the early Spring of 2019 and will be completed in less than 60 days.
The following items are included in the application package, 1 hard copy of each and 1 digital
copy of each on a CD:

Recommended Oxidation Ditch Ivlodifications
West Jefferson, NC - 0,30 MGD Orbal Oxidation Ditch
Designed for CBOD Removal, Nitrification and Denitrification
November 275 201�
WWTP Design Parameters for 0.50 mI= Design Flow:
Oxidation Ditch Activated Sludge
1) Aeration tank volume =
2) Detention time =
3) Sludge age
4) MLVSS
5) MLSS
6) F/M ratio
7) Waste sludge
8) TSS in waste sludge
9) Waste sludge flow
10) Return sludge flow
11) Eff. soluble CBOD5
12) Site elevation
WWTP Design Loading:
1) Design Influent Flow:
0.5 million gallons (0.3 mil gal in outer ring)
24 hours
20 days
2,300 mg/L
= 3,000 mg/L
= 0.16 lb BOD5 per lb MLVSS
590 lb/day (TSS)
= 101000 mg/L
0.0071 mgd
= 25% to 150% of raw waste flow
2 mg/L
2,700 feet
2) Influent BODS Concentration:
3) Influent TSS Concentration:
4) Influent Ammonia-N Conc:
Effluent Requirements (Estimated):
CBODS
TSS
Ammonia-N
Total N
0.50 MGD
375 mg/L (1,5601b/day)
240 mg/L (1,000 lb/day)
20 mg/L
= 5 mg/L
= 10 mg/L
1.6 mg/L (summer) and 3.6 mg/L (winter)
= No limit yet

Analysis of Aeration Requirements:
Oxygen required = oxygen for CBOD removal + oxygen required for NBOD
removal — oxygen savings due to denitrification
Oxygen required for CBOD removal = 1.5 x mg/L) x 0.5 mgd x 8.34
1.42 (biomass production)
= 2,3301b/day — (1.42)(3601b/day)
= 2,330 lb/day — 510 lb/day
= 1,8201b/day
Oxygen required for NBOD removal = 4.33 x (20 — 1.6 mg/L) x 0.5 mgd x 8.34
— 330 lb/day
02 savings (denitrification) = 2.86 x (12 mg/L NO3-N --� N2) x 0.5 mgd x 8.34
= 140 lb/day
Oxygen required =1,820 + 330 - 140 = 2,010 lb/day
The proposed plan is to replace the existing Orbal disk aerators in the outer ring
with S&N AIROFLO aerators.
AeNator Pey foNtrtance:
Desired DO concentration in outer ring = 0.2 mg/L for simultaneous nitrification-
denitrification
S&N AIROFLO field transfer rate
S&N AIROFLO field transfer rate
= 2.1 lb/HP-hr at DO = 2.0 mg/L
2.71b/HP-hr at DO = 0.2 mg/L
Reduction in aerator efficiency is due to field conditions adjustments
for temperature, pressure, DO level, and characteristics of wastewater.
Design temperature
Elevation
a
R
DO concentration
28°C
02 requirement from above calculations = 2,010 lb/day

Oxygen requirement in outer ring = 1,300lb/day (conservative estimate)
Horsepower (HP) required for oxygen transfer (design needs)
= 1,3001b Oz /day _ (2.71b/HP-hr x 24 hr/day)
= 20 HP
To meet design needs, use two 10-HP S&N AIROFLO units in the outer ring.

manufacturer shall have a basic aerator design that has eighteen (25) years experience. The
manufacturer shall certify to not less than five (5) successful operating installations in the United
States meeting the performance specifications as evidence of meeting the experience requirement.
1.5 PERFORMANCE REQUIREMENTS:
A. The aeration equipment, as installed, shall comply with the following:
1
2.
3
PART 2 PRODUCTS
Each aerator shall provide an oxygenation capacity of 4141b OZ per 24-hour
period of continuous operation at standard conditions.
Each aerator shall develop an oxygen transfer efficiency of no less than 2.3 lb
OZ/HP-hr based on motor output power at standard conditions.
The performance requirements for each aerator must be met at an amp loading
no greater than 90% of full load amps.
The 7.5-HP mechanical aerator units shall include (but not be limited to) the following components:
2.1 MOTORS:
A. Each aerator shall be driven by single speed, Premium efficiency, minimum 1.25 SF (at full load
amps, not to be confused with operational loads) horizontal shaft electric motor. The electric
motor shall be an induction motor 3-phase, 1800 RPM, 60 Hertz, 230/460 Volt, TEFC, NEMA
PREMIUM Efficiency. Motor shall operate at 90% or less of its rated full load during normal
operation. The aerator manufacturer shall provide certification that the nameplate data affixed to
SECTION 11000 ELECTRIC HORIZONTAL -ROTOR FLOATING AERATION EQUIPMENT PAGE 2 OF 6

2.2
2.3
2.4
the aerator's electric motor is valid, specific data applicable to that particular motor. The motor
shall carry a manufacturer's warranty from the date of installation.
GEAR REDUCERS:
A. Each aerator shall have a new constant -duty AGMA class III gear reducer possessing a minimum
2.0 service factor based on manufacturer's recommended loads. The gear reducer shall connect
directly to the rotor shaft by twin tapered bushing. The gear reducer shall be connected inline to
the electric motor and driven by a coupling with an elastomeric element. The coupling shall be
attached to the motor & gear shafts by a taper lock bushing instead of set screws, to prevent
damage to the shafts.
B. Each gear reducer shall be equipped with a Vent Breather modified to attach to the gear reducer to
extend the life of the gear oil and reduce maintenance costs. As the thermals change in the cavity
of the gear reducer, moisture vapor is trapped in the proprietary media to be released through the
bottom of the vent housing. This prevents the accumulation of moisture in the cavity of the gear
reducer reservoir. The Modified Vent Breather lowers and stabilizes the relative humidity inside
the reservoir leading to a lower dew point. Lower dew point means no condensation, even when
the machine is shut down. Neither diaphragm nor desiccant style breathers shall be acceptable.
Breathers shall operate at ambient pressure.
C. Each gear reducer shall be fitted by the aerator manufacturer with extefnal seal guards to provide
a labyrinth of protection to the gear reducer seals. Protection of the seal must include not only
protection from splashed water but also protection form atmospheric moisture. Experience has
shown that "off the shelf' gear reducers with no additional protection for the seals will lead to
accelerated seal failure, thus leading to leaks, contaminated lubricants and eventual gear reducer
failure. Experience has shown that an unprotected seal without the benefit of a breather will allow
a gear reducer to pull moisture from the atmosphere around the seal into the gear cavity as units
are cycled on and off. The seal guards provide an extra layer of protection to each of the three
seals in a gear reducer. The seal guards consist of a rubber or Teflon seal plate (depending on the
gears design) with and additional barrier of grease over the seal area for extra protection from
atmospheric moisture. Each gear reducer is drilled and tapped to accept a UHMW hold down ring
to stabilize the seal plate. Gear reducers without external seal guards will typically have a
shortened seal life, thus usually resulting in a shortened gear life. Sim le v-rings or slingers do
not constitute the same protection as described above.
D. Gear reducers shall be mounted in an open area to allow convenient access for maintenance and
for a free flow of air in order to prevent heat buildup and the possible need for external cooling
devices.
DRIVE ASSEMBLY
A shaft mounted gear using a face mounted plate, is attached to the frame with heavy pins to allow
tri-axial movement. The movement allowed by the pin and plate arrangement eliminates critical
alignment issues, thus eliminating misalignment pressure on the bearings in the gear reducer.
Further reduction of possible alignment issues is greatly reduced through the use of an elastomeric
coupling between the motor & the gear. Drive assemblies with rigidly mounted gear reducers will
not be accepted.
SHIELDS AND MOTOR COVER
A. Splash Containment Shields (SCS) consist of a pair of 10' wide shields and structural frame work,
attached to the main frame, on either end of the rotor. The SCS is designed for operation in cold
weather and to provide a clean dry area around the motor and gear reducer and around the tail end
work platform. Thus eliminating winter freeze-up and solids accumulation on the ends of the unit.
The rotor cover material is XR-5 UV resistant geomembrane using textile style double diamond
SECTION 11000 ELECTRIC HORIZONTAL -ROTOR FLOATING AERATION EQUIPMENT PAGE 3 OF 6

2.7
construction. The rotor cover is used in conjunction with the SCS Shields and serves to contain all
mist, reduce heat loss and reduce aerosols.
B. Each rotor cover will be constructed of non -corrosive laminated polyester fabric XR-5. Each unit
will be equipped with a rotor cover for aerosol control and heat retention. This fabric is commonly
used for covers and floating baffle systems. All of the service points are outside of the rotor cover,
but for visual inspections, the cover can be easily opened or removed using spring tensioned
connections when necessary. All fasteners will be 304L stainless steel. The design allows for
enough space around the rotor that an 02 deduct is not required as is common with some of the
tighter fitting fiberglass covers.
HORIZONTAL -ROTOR ASSEMBLY:
A. The Rotor assembly shall consist of an 8-5/8" O.D. flanged torque tube with a 41 1/2" overall
diameter. The flanges shall be indexed to fit the stub shaft hub. The rotor stub shafts shall consist
of a fabricated hub stress relieved to 1200 degrees Fahrenheit and fitted with a 1045 carbon steel
shaft. The shaft to hub fit shall be a heavy shrink fit, performed as the final step of the fabrication.
A specific combination of rotor length and number of blades will provide the required HP to meet
the performance requirements of the aerators called for in this specification.
B. All blades shall be C-shaped, reduced -impact blade design. The blades fora 41 1/2" diameter rotor
shall be attached in banks of four blades of the same length, with the length of the blades in each
bank alternating between 16-3/4" and 13-3/4". Rotor assembly shall be balanced to prevent
vibration. Each bank of blades shall be welded to the torque tube using a specific off set to form a
helix design to eliminate shock loadings. The vertical sides of the C-shaped rotor blade shall serve
as gussets to reinforce the vertical strength of the blade and to relieve pressure on welded
connections. Bolt -on blades are not acceptable.
C. Rotor and blades shall be constructed from 304 stainless steel.
D. The Rotor shall be supported by a tail end stub shaft and a face mounting plate designed in
conjunction with an elastomeric coupling to allow tri-axial movement of the gear to avoid undue
misalignment pressure on the bearings in the gear reduce
ROTOR TAIL BEARING
Each unit shall possess a waste water lubricated tail bearing, requiring no greasing or any
other source of additional lubrication. The body of the bearing is constructed of UHMW
polyethylene. The shrink fitted bronze bushing is designed to wear against the ultra -high
molecular weight (UHMW) polyethylene. The inside of the bi-metallic bushing, also shrink fitted
to the shaft is carbon steel and serves as a visual indicator of wear and as additional mass to
extend the normal wear process and to protect the stub shaft. The manufacturer shall supply
instructions for the replacement of the bi-metallic wear bushings. The bearing shall be constructed
of UHMW polyethylene, with a minimum bearing surface width of 4".The top side, of the
outboard side, of the bearing is cut away for easy visual inspections. Mechanical bearings
requiring greasing, either manual or automatic, will not be accepted.
FLOTATION DEVICES:
Each unit shall contain two (2) stainless steel flotation devices capable of floating and stabilizing
the unit. Each float shall be fabricated from 304 stainless steel having a minimum thickness of
0.0625 inches. All seams shall be welded for strength Floatation devices shall be internally
reinforced and filled with high -density polyurethane foam and completely sealed from the
environment. Flotation stability is mandatory. Prior to assembly, flotation devices shall be sealed
and pressure tested at 3.0 psig.
SECTION 11000
ELECTRIC HORIZONTAL -ROTOR FLOATING AERATION EQUIPMENT PAGE 4 OF 6

2.8 MAIN FRAME:
The horizontal beams of the main frame shall be constructed from 2" x 3"304 stainless steel
structural tubing. All frame connections shall be welded for strength. The main frame shall have
lift brackets sufficient for handling purposes. Each end of the frame shall have a non-skid
platform, welded in place for added structural integrity and to provide convenient platforms for
inspections and maintenance. A splash guard shall be welded to the main frame and extend
downward into the water to help protect the drive assembly from splash created by the rotor.
2.9 CRADLE FRAME:
A cradle frame shall attach the Flotation devices to the main frame and provide adjustment points
to allow adjustments to rotor blade operating depth and respective motor operating amperage..
Cradle frames shall 304 stainless steel. The frame shall be connected to the anchoring system in a
way that the forces resulting from wave action and other movement are not transferred to the
Flotation system. Rubber pads shall also be provided for isolation of the floats from the cradles.
2.10 ADNSTING LINKAGE:
Each unit shall have adjusting linkage attached to each corner of the main frame. Adjusting
linkage shall be capable of changing the operating depth of the horizontal -rotor blades, the
horsepower requirements, and amp draw, and provide leveling of the aerator. Adjusting linkage
shall be fabricated from 304 stainless steel rods with brass adjusting nuts to prevent seizing.
Adjusting linkage shall not be connected directly to the anchoring system nor shall it mechanically
depend on the anchoring system for it to be effective. These adjusting points are necessary to
adjust rotor submergence, thus operating the rotor at the performance levels for oxygen transfer
and mixing, as prescribed by the specification. Floating rotors without these adjustments will
typically under perform.
2.11 ANCHORING SYSTEM:
The anchoring system shall secure the main frame of the aerator in the desired position and limit
its lateral movement potential. It shall not restrict the unit's flotation and shall allow for
continuous aerator operation with fluctuations in water surface elevation required by the specific
application. The anchoring system shall be supplied in accordance with the engineer's
specifications. In this specification, bridge anchoring systems shall be included. The anchoring
system will be constructed of 304 stainless steel.
2.12 ACCESS SYSTEM:
The access system shall provide for safe convenient access to the units for the performance of
scheduled maintenance inspections and simple repairs. The equipment access system shall include
but not be limited to) the following components.
A. Float Mounted Platforms (FMP) attached on the ends of each float to allow safe and
convenient access to both ends of the rotor, without using a boat. The FMP is strapped
around the end of the floats and provides a non-skid surface and a hand rail, for easy on &
off access.
B. Safety Masts; (2) Per Unit. The Safety Masts is an "L" shaped bracket attached to the
frame at each end of the rotor for the attachment of a safety harness, supplied by the
customer. A chain allows linkage adjustment to allow the operator the bend as low as
required, but limit movement beyond a certain point.
SECTION 11000 ELECTRIC HORIZONTAL -ROTOR FLOATING AERATION EQUIPMENT PAGE 5 OF 6

C. Vertical Hand Holds (VHH): (2) Per Unit. VHH is simply a vertical bar attached to the
frame in a location convenient to operators for the transition step from the float platform
to the frame.
D. Drop Steps: Bridge mounted drop steps provide elevation adjustments to optimize the
ergonomics of safe and convenient access to both ends of the floating rotor. They are
constructed of A36 steel with non-skid surfaces and handrails and hot dipped galvanized
after final fabrication. Adjustable linkage to secure and stabilize the floating rotor is

changes.
® Gear reducers shall be supplied with S&N Aeration Duty Gear Lube.
® Motor and Gear Reducer Drive Devices: Flex Drive Assembly consisting of a shaft
mounted gear using a face mounted plate, is attached to the frame with heavy pins to
allow tri-axial movement. The movement allowed by the pin and plate arrangement
eliminates critical alignment issues, eliminating misalignment pressure on the bearings
of the gear reducer. Further reduction of possible alignment issues is greatly reduced
through the use of an elastomeric coupling between the motor & the gear.
® Drive Assembly Covef°: The cover design is hinged to allow unimpeded access to the
drive assembly for O&M inspections and repair. This cover has an open design to
reduce moisture and solids retention in the drive assembly area.
® Horizontal Rotor Assembly: shall be constructed of 304 Stainless Steel. The torque tube
is fitted with welded flanges on both ends to receive eight (8) bolt stub shaft assemblies.
The blades are welded to the rotor for strength and then balanced. The Airoflo rotor
design shall include a unique blade shape with a C4haped base and a blade
placementpattern of alternating long & short blade lengths to maximize mixing and
oxygen transfer.

High Molecular Weight) bearing block and wear sleeves (Bronze and Carbon Steel)
Section 11001 Floating Aeration Rotors - Scope of Supply Page 1 of 4

attached to the rotor shaft using a heavy heat shrink. The UHMW bearing block is
uniquely machined to carry the weight of the rotor while allowing wastewater to flow
through the bore for lubrication. A cutaway design provides an easy visual inspection of
the condition of the bearing assembly. The maintenance free bearing assembly is
designed to wear out over time, while eliminating scheduled greasing and possible
catastrophic failure.
® Rotor Support: In -line Flex Drive Assemblies will include a Single UHMW Tail end
bearing with a face mounted swing plate supporting the drive end. UHMW polyethylene
self -wastewater lubricating (non -greasing, maintenance free) rotor bearing with bi-
metallic wear sleeves are designed to absorb the wear and protect the shaft. The
maintenance free UHMW bearing will eliminate the monthly greasing labor and
possible contamination of the basin.
® Floatation Devices, Cradle Frances &Vertical Adjustable Linkage: Stainless Steel
foam filled floats are mounted to the main frame with Stainless Steel cradles. The
connecting linkage between the cradle and the frame is adjustable to vary the rotor
submergence and to control amperage.
® Main France: The main frame is constructed primarily of 304 stainless steel structural
square tubing. Non-skid platforms are welded to both the drive end and tail end of the
frame for secure footing and safe access during O&M inspections.
® Fasteners &Threaded Rods: all bolts, threaded rods, pins and clips will be 304
Stainless Steel. All adjustment rods will have brass nuts and all bolts will have brass
lock nuts to prevent seizing.
® Anchoring: This system shall be supplied with a Bridge Anchoring System (BAS). The
BAS will attach to the existing bridge and allow the unit to float level and operate at the
various water levels required for the application, while securing the unit in place and
limiting lateral movement.
® Rotor Cover: Each unit will be equipped with a rotor cover for aerosol control and heat
retention. Each rotor cover will be constructed ofnon-corrosive laminated polyester
fabric XR-5. This fabric is commonly used for covers and floating baffle systems. All
of the service points are outside of the rotor cover, but for visual inspections, the cover
can be easily opened or removed using spring tensioned connections when necessary.
All fasteners will be 304L stainless steel.
® Shields: SCS (Splash Containment Shield) with Rotor Cover
The SCS consists of a pair of 10' wide shields and a structural frame work on over each
end of the rotor. The shields are designed to provide a clean dry area outside of the
rotor and particularly around the motor and gear reducer. The shield is 10' wide and in
freezing weather, will limit ice buildup on the unit. The shield system shall
incorporate extra protection with shaft seals which will prevent waste water from
migrating along the rotor shaft to the seal & bearing area of the gear. The rotor
cover material is Seaman Corporation's XR-5 UV resistant geomembrane using textile
Section 11001 Floating Aeration Rotors -Scope of Supply Page 2 of 4

style double diamond construction. The rotor cover is used in conjunction with the SUS
Shields and serves to contain all mist, reduce heat loss and reduce aerosols.
Electrical Panel:

the anchoring point of the aerator.
® EZ Access Systems: Based on our 25+ years of experience, we recommend a
simple access system to provide safe & easy access for O&M inspections and
light repairs.
® Vertical Hand Holds (VHH): (2) Per Unit. VHH is simply a vertical bar attached
to the frame in a location convenient to operators for the transition step from the
float platform to the frame.
® Float Mounted Platforms; EZ-Access float mounted platforms are designed to
provide a flat non-skid surface and a handrail on the ends of the floats, thus
providing safe access from the bridge mounted drop steps or the levee of a
lagoon. This fixture is considered a wetted (submersed) part and is constructed of
stainless steel.
® Safety Masts; (2) Per Unit. The Safety Masts is an "L" shaped bracket attached
to the frame at each end of the rotor for the attachment of a safety harness,
supplied by the customer. A chain allows linkage adjustment to allow the operator
the bend as low as required, but limit movement beyond a certain point.
® Drop Steps: Bridge mounted drop steps provide elevation adjustments to
optimize the ergonomics of safe and convenient access to both ends of the
floating rotor. They are constructed of A36 steel with non-skid surfaces and
handrails and hot dipped galvanized after final fabrication. Adjustable linkage to
secure and stabilize the floating rotor is included with the drop step assembly.
Internal ladder may also be included to compensate for site specific water level
and freeboard distances.
