Subject: Request for Authorization to Construct
A Sludge Thickener,
At Guilford Mills, Inc. —Guilford East WWTP
Kenansville, NC
NPDES Permit No. NC0002305
Dear Mr. Goodrich :
This letter is to request an Authorization to Construct a Sludge Thickener at subject
facility. The facility wastes a portion of it's return activated sludge (RAS) to a 0.5 MG
holding tank and the remainder is put on ten (10) sand drying beds. The holding tank is
used to hold solids that are periodically pumped out for land application. The plant
wants to install a sludge thickener for several reasons. A thicker sludge in the holding
tank will effectively increase it's capacity, eliminating a bottleneck that currently prevents
sludge wasting at times when it is needed for proper control of sludge age. Also, the
plant wants to have biosolids with greater nutrient value to maintain the viability of the
land application program. This request also covers the addition of aqua ammonia as a
nutrient to be fed to the first aeration basin.
This submittal includes:
1. This letter of request.
2. Three (3) sets of Detailed Plans and Specifications for the installation of aBaycor
Model MDS 42168-500 Drum Screen, and related equipment, including
manufacturer's specifications and performance information.
3. Two (2) sets of Design Calculations and Hydraulic Profiles.
4. Two (2) copies of a Flow Schematic, with sizes of major components (8-1/2" x 11").
5. Construction Sequence Plan for continuous operation.
6. Item 6 of the submittal requirements requires assurance that the facility can comply
with permit requirements, for any system or component that does not have well -
established treatment capabilities. We feel that no additional information is required
address this requirement, since the proposed sludge thickener has well established
treatment capacities.

Design Calculations for Proposed Sludge Drum Thickener Installation
SYSTEM CAPACITIES, FLOW RATES AND ASSUMPTIONS:
System Volume:
Aeration Basin #1 2.0 MG
Aeration Basin #2 1.0 MG
Clarifier #1 0.5 MG
Clarifier #2 0.5 MG
Total 3.5 MG
MLSS, max.: 10,000 mg/L, worst -case, assumed for calculations
Target sludge age: 30-50 days, use 30 days as worst -case in calculations
Total suspended solids (TSS), final effluent: range 0 to 165 mg/L(based on permit limits
of 2,071 Ib./day and 1.5 MGD), use 0 mg/L as worst -case in calculations
Waste activated sludge (WAS): typical range 15,000-20,000 (mg/L orppm) or 0.015-
0.020 Ib./Ib., use 0.015 Ib./Ib. in calculations
Maximum effluent flow rate: 1.5 MGD, permitted maximum
Sludge thickener flow or throughput: rated up to 200 gal./min, use 75 gpm in
calculations, the flow rate used in pilot testing.
CALCULATE SLUDGE WASTING REQUIREMENTS:
Sludge age, days
= ((solids in inventory, Ib.) + (solids in effluent, Ib.)) / (sludge wasted, Ib./day)
Rearranging formula,
Sludge wasted or sludge wasting requirement, Ib/day
= ((solids in inventory, Ib.) + ( solids in effluent, Ib.)) / sludge age, days
Solids in inventory in WWTP:
3.5 MG X 8.34 Ib/gal X 10,000 ppm = 291,900 Ib
Solids in effluent, Ib.
1.5 MGD X 0 mg/L = 0 Ib.
Sludge wasting requirements:
Calculate weight of solids to be wasted:

Design Calculations for Proposed Sludge Drum Thickener Installation (Cont.)
Calculate volume of solids to be wasted:
(9,730 Ib./ day ) / ((8.34 lb./gal. X 0.015 lb./lb.)) = 77,778 gal./day
DETERMINE SYSTEM CAPACITY REQUIREMENTS:
Calculate worst -case time required to operate thickener daily:
77,778 gal./day / (75 gal./min. X 60 min./hr) = 17.3 hr/day
Note: The above calculations are based on worst -case data or assumptions from a
review of the plant's current operating data.
Conclusions: The throughput capacity of the proposed sludge thickener is more than
adequate to meet the daily wasting requirements of the WWTP. The sludge thickener is
expected to have effluent solids concentration of about 6%, but this is not a determining
factor in the above calculations. By thickening WAS from 2.0% to 6.0%, the thickened
sludge will have only 33% of the original volume, meeting the objectives of this project.
It is anticipated that over time, as the sludge thickener is operated, the MLSS will be
reduced to the range of 3,500 — 5,000 mg/L. Also, the flow rate may be increased above
75 gal./min as the operators gain experience in the operation of the unit. Both of these
actions will greatly reduce the daily operating time of the thickener to maintain the
desired sludge age. In normal operation, daily operating time is anticipated to be less
than one shift, i.e. less than 8 hours.
The capacity of the auxiliary components of the system are adequate to support the
maximum rated throughput of the sludge thickener, 200 gal./min. The filtrate return
pump is rated at 365 gal./ min. for the design conditions. The polymer blending unit is
rated at 8 gal./min polymer feed, which exceeds the maximum polymer feed rate
determined by the ,,;H�gd ;;ing sample testing.

One (1) Baycor Model MDS 42168-500 Drum Screen
File 00-2441
Gentlemen:
We thank you for your continued interest in the Baycor Model MDS42168-500 screen.
The revised proposal we discussed is attached. Below, we have summarized some key
aspects of the proposal:
. The screen will be fitted with eight (8) removable screening media panels.
Screens are installed from the solids discharge end.
. The "Dual -Wash" system NEIvIA 4 splash=proof panel does not include a 120V
single phase step down transformer. Baycor does not have a standard design for this
add -on.
. The heavy duty nylon wheels require periodic greasing.
. The screen should be installed with a 3 R. wide service platform on all sides
except the discharge end. The discharge end should be fitted with a 4 ft. service
platform beyond the discharge. The platform is by others. The drive motor has
been upgraded from 2 to 3 horsepower.
. The discharge chute and doors are not included.
. The new price is $78,000.00.
. Payment term have been revised, but do not represent terms discussed at the job
site.
. Delivery schedule has been approved.

. Price includes freight to the job site.
. One (1) trip of start-up has been included without additional cost to Guilford Mills.
. The proposal includes a discussion to make this a reference plant for Baycor.
. Maximum backwash flow is apparently 30 GPM (7a 40-50 PSI.
. The nozzles are designed for use with filtered water supplies. The solids in the
spray water supply should not be larger than 0.004". Using recycled water can work
with solids of the size; still the nozzles will require more frequent cleaning.
. The factory expects the backwash system will run on a cycle that includes spraying
for 40 seconds and off 5 to 10 minutes.
. The screen has been sized properly so that flooding protection is not required.
We are hopeful that this revised proposal will be acceptable to you. If we are favored
with a purchase order, please address the order to:

BAYCOR's "LVENFLGW" headbox is a non -clogging, pressure -reducing design,
providing a positive, .even laminar flow discharge offboth sides of the headbox without deep
wells where solids might settle.
"DUAL -WASH" BACKWASH SYSTEMS
Backwash is via nozzles on 2" centers along two external integrated water spray bar systems,
one on each side, all of304L stainless steel coon. Our systems includes the upgraded
"DUAL -WASH" option which divides each backwash spray bar in half along ifs length.
The flow, frequency and duration of backwash at the inlet and outlet ends can therefore be
controlled independently and as required for cleaning of the media and optimal screening
and backwash performance. Nozzles are easily accessible via the "Swing -Out" feature as
is shown in Item D (Dwg 971017•GA1).
The "DUAL -WASH" system includes a 120V/1 phase control panel with programmable
timers and manual and solenoid valves. "DUAL -WASH" report is attached.

A common question with regard to the operation of BAYCOR's series of DRUM -SCREENS is
"How much backwash water will we need?"
The purpose of this report is to address this question. Many applications may not require backwash
at all, but then again, many do. This will depend on the type of application more than anything.
Generally speaking, all DRUM -SCREENS have two spray bars for backwash, one on each side.
One side is always spare.
Nozzles arc spaced about every 2' , and spraybars are about as long as the screening media.
For example, if we consider an MDS 48120, (the 42120, 60120 and 72120 all have the same
spraybars) the screening media is 120" long and so is the spraybar_ This means that there are 60
nozzles per side. Each nozzle can deliver up to '/ usgpm at about 40 to 50 psi when using clean
water. This would give us a maximum flow rate of 30 usgpm per side at full flow. However,
typically the backwash is throttled hack. We do not need to have 12" of spray shooting through the
drum. We look to optimize the backwash only for solids removal efficiency with minimal water
consumption.
So while we should look to hook up for 30 usgpm per side (the maximum flow rate), in fact, we can
use much less than this in real operation
"Dual -Wash" is a BAYCOR innovation that allows us to offer different backwash needs at the inlet
half of the drum and at the solids discharge half of the drum. In essence, each spray bar is split in
half, so that four separate backwash elements can be utilized however required.
With "Dual -Wash", consumption can be further optimized. In cases where back wash is required,
the inlet end of most applications will require more back wash than the discharge ends. Frequency
and duration can be set independently for each end Each end can further be throttled to something
less than the full flow as required.

Dear Sir:

Mr. Mark Morgan from "Heyward" asked me to explain the
reason we choose the system we offered in our letter dated
(oct.12/00).
The subject being W.A.S. (Waste Activated Sludge).
We were given the flow of 200 usgpm influent 1 %, desired solids
output 6% with polymer. We have pioneered W.A.S. screening
and thickening as far back as 1989-1990 and have many
installations. From what I understand the other offer was a much
smaller unit, something in the 36120 size and with a 102" or 500
micron opening.
If we use a comparable unit, our price would be S59, 600.00 us
dollars. Our smaller 36120 unit is identical, to what we quoted,
only "smaller". The screening area of the 36120 is about 95 sqft,
and the 60200- 250 is 261 sqf . In other words, our system is
almost 3 times larger. We use woven wire mesh and the last unit I
seen from "Andriz" was wedge wire. Wedge Wire is not
acceptable in our opinion and experience, because of the wide flat
surface and reduced opening area. RECEIVED ! DENR ! DWQ

In a small diameter drum and short length, the solids don't have a
chance to dewater and produce only very "sloppy" solids 2-21/2
at best and the filtrate retaining many particles - "a dirty filtrate'
Results with our larger unit, the solids discharge would be 6% to
10% depending on the quantity of polymer. The filtrate solids
reductions are between 97% to 99% with our system. A marked
difference with our `BA YCOR SYSTEM'.
There is no real comparison with Baycor or Andriz - Contrashear
unit. Our unit system description clearly spells it out.
We are including a typical quotation specification for our system,
and if you have any questions or require more explanation, we
would be more than pleased to accommodate you.
We very much appreciate your interest in "Baycor systems", and
are ready to serve you.

MDS, Ultimac & SDS Series
Drum -Screen Systems

What it Is an d a D Y 1t Works
Operational Synopsis
The BAYCOR MDS DRUM -SCREEN is an internally fed screening device with the flow being fed into the headbox and distributed
onto the internal rotating surface of the screening cylinder.
The MDS DRUM -SCREEN has a solid, stainless steel unibody construction, a screening cylinder with interchangeable screening
panels and a headbox assembly.
A standard variable speed drive electric gear motor rotates the drum screening cylinder assembly between 3 and 10 rpm. The
screening cylinder rotates slowly and quietly on four fully engineered wheels.
Interchangeable screen panels, of stainless steel woven wire mesh from 17 microns and up, allow for precise adjustment of the
openings in the screen to provide the best screening/solids capture performance to meet your applications requirements.
BAYCOR standard features allow you to precisely tune for the performance you want and need.
The liquid in the headbox/distribution chamber is directed over weirs onto the internal rotating surface of the screen. Solids
remain on the surface of the screen while the liquid goes through the screen media.
As the screen rotates, the solids roll on the face of the screening cylinder
and are intercepted by the diverter flights. The diverter flights are mounted
spirally, with the spiral pointing to the discharge end of the cylinder. As the move Diverhtscontinualy
move solids to
screening cylinder rotates, the solids drop off one diverter flight to the next Influent discharge end Interchangeable panels
until they reach and drop off of the discharge end of the cylinder. The y of stainless steel Woven
wire mesh from
solids can drop off into a container, conveyor chute or solids dewatering 17 microns and up
device for further processing to reduce the water content and/or increase
the solids dryness.
The unibody design of the MDS DRUM -SCREEN includes a flanged
discharge pan that directs the treated water to a tank, channel or pit, or on
through further piping. Variable
speed
The spraying/backwash system (outside) located on the upper half of the d"Ve
cylinder, will wash off any solids, grease or other materials sticking to the motor Filtrate
face of the screening media and thus keep the inside of the cylinder dean.
The backwash can be set manually or timed or programmed to operate on
an as needed basis.
The MDS DRUM -SCREEN, with its robust and simple, stainless steel
unibody construction, its interchangeable screen panels and variable speed
drive is truly the state-of-the-art in screening technology.

What Makes BAYCOR Different
Design Philosophy
The BAYCOR design focuses on simplicity. Our goal is to make our systems perform better, make them more reliable, make them
simpler to operate and easier to maintain. Our systems are designed to be flexible to meet with the demands of day to day
operations. With more than 150 units installed in all sorts of applications, we believe that we are fulfilling our philosophy with our
advanced solids/liquids separation and thickening technology.
The simplicity of our unique design simply gives us better performance. We build our units to ensure that reliability over the long
term will not be a concern. Our systems represent permanent investments that retain their value better than any other piece of
wastewater treatment or process equipment. Tunable, adaptable performance that operators can understand and adjust to meet with
the needs of their operations make BAYCOR the systems of choice.
At BAYCOR we have incorporated a number of "Firsts" into our Advanced Designs:
Drum Our drum is a fully engineered, structural element of our design and is independent of the screening media. The
robust drum is channelled and panel -ready, and can be outfitted with panels of any size opening. Removable
diverter flights are also part of the drum assembly, and are attached to the channels.
Panels Panels are available in a variety of opening sizes and types. As a standard, we use a robust multi -weave media of
304 stainless steel construction. (Other grades of stainless and other alloys are also available.) Panels are easy to
change out. In difficult solids/liquids separation applications, we have the ability to "tune" the openings in the
drum to match the process and operational needs required. It is as easy to do in a pilot unit as it is in the full scale
system installed at the plant.
Wheels As simple as wheels are, BAYCOR has made a science out of them. Our wheels have been totally designed for
maximum life and minimum maintenance. Two heavy duty dual -row ball bearings serve each wheel. Wheels and
bearings operate at a small fraction of their maximum load. We use top quality bearings 100,000 hours. A unique
feature of our advanced design also eliminates the need for separate guide rollers or cam followers. BAYCOR
advanced, in-house wheel design is engineered simplicity.
Unibody BAYCOR unibody construction is simpler, cleaner and stronger than conventional designs. Sturdy enough to meet
pulp mill standards, our unibody is destined to last for generations. Built on pairs of feet of uneven length, we add
a natural elevation to the discharge end of the unit. The cliverter flights in the drum slowly move the solids forward
and slightly uphill, out of the water that naturally runs back. The unibocly also automatically incorporates an
integral drain pan.
Experience Since BAYCOR introduced our design and pioneered the use of woven -wire mesh in the screening industry many
years ago, we have built up an enormous amount of application experience. BAYCOR's unmatched Application
Experience and Factory Support are at the forefront of the technology. Commissioning and start-up optimization
are part of a system's purchase. There is no substitute for experience.

Applications for the
BAYCOR MDS Drum -Screen

The Pulp and Paper Industry
MDS in de -inking sludge thickening service, prior to screw press.
The advantage that the MDS delivers in dryer solids was required to
meet with the dry solids required from the press (50%+).
Two MDS units in fibre recovery/service. The BAYCOR advantage
was required to capture fibre that was previously lost to treatment:
The de -inking sludge comes off of flotation clarifiers at 2-3%, with as
much as 40% clay or ash. The solids come off our MDS at 12 to 15
to 18% allowing the press to meet its goal.
The recovered fibre is also cleaned and thickened at the same time.
Exceptional MDS performance - each unit recovers more than 6-9
tons of fibre per day, achieving payback in weeks after installation.
Two MDS units in secondary (waste activated) sludge thickening
service. Free of ---1 % is pretreated with polymer at about 7 to 8 kg/
ton of dry solids.
The BAYCOR MDS system thickens the secondary sludge to 8 to
10% consistently. The BAYCOR advantage was required to
achieve dry solids content that would allow blending of the
thickened WAS with thickened primary sludge to allow for effective
dewatering in a screw press, prior to burning of the pressed solids.

Trusted and Proven
The PolyBlend PB Series is
the original multi -zone
motorized PolyBlend sys-
tern. Improved and relined
over 15 years, the PB
Series is the most popular
liquid polymer feeder ever
offered, with over 10,000
units at work around the
world.
Various models cover a
polymer solution flow range
from 0.1 to 20 USGPM_
Unlike most polymer feed-
ers, the PB Series works
equally well at very low
How rates.
Compact
and Portable
The PB Series is compact.
Its footprint is only 1.to
square feet depending on
frame size. It is lighter
than most other polymer
feeders, making it ideal for
portable use or where
intermittent use requires
the system to be stored in
one location and used in
another.
THE ORIGIN A L
el008
The Right Energy at
the Right Time
The patented multi -zone
mix chamber provides uni-
form dispersion energy at
the moment of initial poly-
mer wetting. This high
energy mixing prevents
agglomerations, eliminat-
ing the need for extended
mixing and aging time. The
partially swollen polymer
then enters a low energy
zone where activation con-
tinues without the destruc-
tion associated with batch
mixing.
More for Less
Replacing a batch mixing or
static mixer system \vith
a PB Series results in
reduced polymer con-
sumption (20-50%) and
improved performance;_
Polymer use is reduced by
eliminating agglomerations
(wasted polymer) and frac-
tures (broken molecules).
Improved performanoc is
realized, by exposing more
charge sites_

The USFilcer - Stranco Products
REM -ID digital display pump con-
troller serves as either a pump remote
control station or proportional pump
controller (4-20 mA input) or loth_
REM -ID can bc used to vary thc
output of any Liquid Metronics In-
corporated (LMI) series A7, B7 or C7
metering pump (pump must be in
external mode). Simply connect ei-
ther end of the four conductor table
(4 conductor cable and connectors arc
standard) to the external inpur jack of
the LMI pump and the ocher end to
the four conductor cable on the bot-
tom of the controller -
Power is supplied by the 15 VDC
source from the LMI pump through
the four conductor cable.
Controller output in the form of con-
tact closures of B0 ms duration trig-
gers the LMI pump. In the internal
mode, output is 0-100 strokes per
hour (SPH) or 1-100 strokes per
minute (SPM). Up and down pres-
sure sensitive, membrane keys vary the
output shown on an LCD digital
display.
In the external mode, output is from
0-]00 SPH or 0-100 SPM directly
proportional to tilt 4-20 mA analog
inpur signal. Tcn feet of three con-
ductor cables and connectors are sup-.
plied stumdard for 4-20 mA connec-
tion_ Controller impedance is 220
ohms_ Zero and span adjustments
In thc "OFF" position, the 15 VDC
power source will be present but the
controller output will bc zcro. The
display will read "OFF."
The polycarbonatc-plastic, NEMA
4X enclosure may be easily wall -
mounted near to or remote to the
associated pump. Standard cable/
connector sets for connecting pump
controller are available from USFilter
