Permit Modification Application
Guilford East Site
Kenansville, Duplin County
Dear Ms. Sullins:
Please find enclosed one Standard Form C NPDES permit
modification application for the referenced facility. Also,
find enclosed a Preliminary Engineering Report (PER)
developed by Hydroscience, Inc., which contains data from a
30 day sampling study performed on the Guilford East
wastewater treatment: plant (WWTP).
Guilford Mills wishes to increase its permitted effluent flow
rate from 0.965 MGD to 1.15 MGD. The reason for the expansion
is increased production levels at the site. The plant has
added 3 new let dye machines, and two more are planned for
the near future. The plant is also planning to add two new
tenter frames. The plant expects to reach full utilization of
existing equipment soon.
Water usage increases due to production increases to date
have been offset by water conservation protects. The water
conservation activities reduced flow into the WWTP by 120,000
GPD during late 1992. However, it is estimated that a
permitted flow rate of 1.15 MGD will be needed to handle
expected production levels for the next two years, and that
an increase to 1.25 MGD will be needed in two years. Guilford
Mills is requesting the increase to 1.15 MGD because it is
felt that a stepwise approach to the ultimate permit goal of
1.25 MGD is necessary.
The highest monthly flow through the WWTP during the past
year was 0.983 MGD in May 1992. Average monthly flows were
very close to the permitted flow rate of 0.965 MGD until
October 1992 when the water conservation measures were
enacted.
There are several issues pertaining to the operation of the
WWTP and the condition of the effluent which have been
brought to light by the Hydroscience 30 day study and the
State. These issues will be discussed below.

Chronic toxicity has been a problem for the WWTP off and on
for the past year and a half. During the 30 day study of the
WWTP, a full range chronic toxicity test was conducted. This
test resulted in a chronic value of 18% for the Guilford East
effluent. The current permitted in -stream concentration of
the effluent is 19%. Th1.s would seem to explain why the plant
has been having trouble with chronic toxicity. At the
requested flow rate the in --stream effluent concentration
would be approximately 23%. Guilford Mills is actively
pursuing the cause of the toxicity problem. It is suspected
that undegraded and partially degraded surfactants may be the
primary cause of the toxicity problem. Guilford Milis has
contacted Mr. Larry Ausley of the Aquatic Toxicity Unit, and
information obtained from Mr. Ausley has been very helpful in
narrowing the field of suspected chemicals/substances. The
plant is currently carrying out investigations to determine
the types of surfactantswhich exist in the effluent and
their effect on toxicity. Based on the success other textile
companies have had in isolating toxicity problems. Guilford
Mills believes the Guilford East chronic toxicity problem
will be overcome.
The Guilford East WWTP received an NOV in 1992 for excessive
BOD levels during May of 1992. There has been some concern
that the clarification/thickening capacity of the two
existing 55 foot diameter clarifiers is not adequate to
handle the increased flow and solids flux. Hydroscience has
addressed this concen in the PER for a permitted flow of 1.25
MGD and a sludge recycle rate of 50%. Using the same
calculation for a permitted flow of 1.15 MGD and a recycle
rate of 50%, the Guilford East WWTP can carry an MLSS
concentration of 4600 MG/L and still not exceed the
recommended solids loading of 15 lb/day/ft2 for textile
wastewaters. Guilford Mills will ensure the solids loading to
the clarifiers does not exceed this value by controlling the
solids retention time (SRT) and the recycle flow rate.
Guilford Mills is currently instituting the SRT control
scheme, and through this control method the MLSS will be
controlled. The solids flux approach to operating the
clarifiers is also being adopted, and through this approach
the operators will be able to control solids in the
clarifiers. Guilford Milis believes that as these control
methods are instituted, the WWTP operators will be able'to
better control suspended solids in the form of pin floc or
other poorly settling floc. It is believed pin floc and poor
settling has been the major cause of BOD problems in the
past.
There were several concerns noted by Hydroscience in the PER.
Guilford will address some of these concerns in the near
future to ensure the WWTP can handle the requested flow -rate.

-3-
The current pumping system which moves water from the
equalization basin to Aeration Basin No.l can handle 1.08
MGD. This system will be upgraded (or replaced) with a
pumping system which can handle 1.15 MGD. In addition, the
flow control system on the current pumping system will be
upgraded or replaced. The scum removal system on the
clarifiers will be cleaned out, and sprays will be added to
help prevent future clogs. Flow meters will be installed on
the sludge recycle lines and the sludge wastage lines. In
addition, a flow totalizer will be installed on the sludge
waste lines, so that wastage rates can be calculated and
controlled. Finally, the V-notch weir on the final effluent
basin will be modified so that the new flow rates can be
properly measured.
Following the completion of the WWTP improvements listed
above, Guilford Mills will consider future improvements to
the system. The Di.scostrainer system used for lint removal
before the equalization basin will be reviewed and a decision
will be made on whether to replace it with a better system.
Until that time the current Discostrainer system will be
maintained to provide maximum lint removal. Guilford Mills
willconsider by passing Aeration Basins No. 2, 3 and 4 since
the H yclroscience PER shows that this additional aeration
volume may not be needed.
The company will also consider the improvement of the sludge
handling system. Potential improvements include a sludge
filter press, conversion of the aerobic digesters into sludge
thickeners, and a chemical coagulant addition system. These
improvements will allow plant operators to waste adequate
amounts of solids at all times. The current system (sludge
drying beds) is time consuming and labor intensive and
restrict the amount of solids that can be wasted. Finally,
Guilford Mills will consider adding a third clarifier to
provide the WWTP with adequate clarification capacity for
future plant production increases.
Guilford Mills is committed to minimizing wastewater flow,
toxicity and effluent concentrations of pollutants. This has
been shown through the water conservation work, the toxicity
reduction efforts, and the implementation of SRT and solids
flux control schemes. However, the prospects for growth of
business for the Guilford East site are excellent, and the
capacity of the WWTP must be increased to handle the
increased production. We hope that the State will consider
all these factors while reviewing our application for the
increase in permitted flow.

1.0 INTRODUCTION
The Guilford East Plant is located near Kenansville in Duplin
County, North Carolina and is owned by Guilford Mills, Inc. The
Guilford East Plant dyes and finishes textiles for use in
automotive upholstery. The wastewater from the Plant is treated
on -site in a conventional wastewater treatment plant (WWTP) and the
MR
treated water is discharged.
1.1 BACKGROUND
The Guilford East WWTP discharges to the Northeast Cape Fear River
under NPDES Permit Number NC0002305 from the North Carolina
Department of Environmental Management (NCDEM). This Permit limits
the discharged flow to 0.965 million gallons per day (MGD). The
Guilford East Plant plans to increase its production rate but the
current level of production already generates as much wastewater as
the Permit will allow. In order to increase production, the Permit
will have to be modified to allow higher flow rates to be
discharged. Guilford Mills has therefore requested that NCDEM
modify this Permit to increase the discharge limit from 0.95 MGD to
1.25 MGD.
NCDEM has indicated that the proposed modification to the NPDES
Permit may be granted if certain conditions are met. One of these
conditions is that Guilford Mills submit a Preliminary Engineering
1

_r}
Report (PER) describing how the WWTP will be upgraded to achieve
the limits of the modified permit at the increased flow rate.

NCDEM has indicated that mass loading limits of all contaminants
will remain unchanged if the flow limit is increased. Since the
flow limit will be increased by a factor of 1.30, all contaminant
concentration limits will be decreased to 1/1.30 (or 0.77) of the
current concentration limits. This means that the WWTP will have
to treat an increased flow and provide an increased level of
contaminant removal at the same time. This PER will describe how
the WWTP can be upgraded to achieve the necessary level of
treatment at the increased flow rate.

2.0 EXISTING WASTEWATER SYSTEM
The current WWTP at the Guilford East Plant is a conventional,
activated sludge treatment facility and is typical of treatment
facilities for dyeing and finishing operations. Figure 1 presents
a schematic diagram of the WWTP while Figure 2 is a flow diagram.
2.1 SOURCES OF WASTEWATER
The long-term average flow rate to WWTP is 840,000 gallons per day
(GPD) . This flow comes from four main sources; process water, non -
contact cooling water, steam condensate, and sanitary waste.
The process wastewater accounts for most of theNflow and organic
loading to the WWTP. The process water comes from dyeing
operations and from wash water. The wash water is generated in the
initial washing of the textiles to remove knitting oils.
Polyester, which is the most important product at this plant, is
dyed 7 days a week in jet dyeing machines. Nylons are dyed in beam
dyeing machines 5 days a week. Smaller jet dyeing machines are
operated at intervals to conduct trial runs. All dyeing is done on
a batch basis.

2.2 PRIMARY TREATMENT
The production activities at the Guilford East Plant generate a
wastewater flow with widely varying characteristics. The various
contributing wastewater streams from the Plant are combined to form
the WWTP influent. Primary treatment of the influent consists of
course screening, fine screening, and equalization.
fin The first step in the existing primary treatment is coarse
screening. The combined influent flows to a bar screen which is
`' designed to remove coarse solids. The screen is approximately 3
feet wide with openings which are approximately 1.5 inches wide.
1.9
The screenings are manually removed. After coarse screening, the
MR wastewater flows to a parshall flume where the flow is recorded and
samples are taken by an automatic sampler.
Mol
The next step in the primary treatment is fine screening. The flow
mq
from the bar screen/flume enters a wet well where it feeds an
influent pump station. This pump station consists of three self-
Pci
priming pumps each rated at 850 gallons per minute (GPM). The
pumps deliver the wastewater to a DS-393 Discostrainer. The
screenings, which primarily consist of lint, are automatically
mm
will bypass the screen by overflowing the wet well. The screened
rin wastewater and any wet well overflow combine and flow by gravity to
1051
dropped into a dumpster located beside and below the screen. If
the Discostrainer is hydraulically overloaded, the additional flow

fml
i p
the North end of the equalization basin.
The equalization basin is an in -ground, concrete lined, rectangular
min basin with sloping sidewalls and 2.0 million gallons (MG) of
capacity. This basin is lined with a polyethylene liner. Three 30
horsepower (HP) floating aerators are located in the equalization
basin to provide mixing and minimize settling in this basin.
lwl
m., The wastewater is pumped from the south end of the equalization
basin to secondary treatment by a pair of Crown Model P.06 LC.14X
im
self -priming pumps each rated at 750 GPM. An automatic flow
control system is designed to maintain a constant flow rate, but
flow is manually controlled at this time.
2.3 SECONDARY TREATMENT
mq
Secondary treatment consists of conventional activated sludge
treatment followed by secondary clarification.
mq
The flow from the equalization basin is pumped to the South end of
Aeration Basin No. 1 which is also where the activated sludge is
returned from the secondary clarifiers. Like the equalization
basin, Aeration Basin No. 1 is an in -ground, concrete lined,
rectangular basin with sloping sidewalls and a capacity of 2.0 MG.
Unlike the equalization basin, this basin does not have a
fon polyethylene liner. The water level in Aeration Basin No. 1 is
5

approximately 5 feet higher than that of the equalization basin.
The mixed liquor in this basin is aerated by two 30 HP and six 20
HP floating aerators. The mixed liquor overflows a weir in the
Northeast corner of Aeration Basin No. 1 and flows by gravity to
Aeration Basin No. 2.
Aeration Basin No. 2 is an in -ground, concrete lined, square basin
with steeply sloped sidewalls and a capacity of 1.0 MG. It is
equipped with four 20 HP floating aerators. The mixed liquor
overflows a weir and flows by gravity to Aeration Basin No. 3.
Aeration Basin No. 3 and No. 4 are circular concrete tanks each
with a capacity of 0.5 MG. Each is equipped with one 20 HP
floating aerator. Mixed liquor from Aeration Basin No. 3 overflows
a weir and flows by gravity to Aeration Basin No. 4 where it
overflows another weir and flows by gravity to a concrete splitter
box.
After entering the splitter box, the mixed liquor is divided into
two streams. Each stream flows by gravity to one of two
clarifiers. The two clarifiers are identical, 55-foot diameter
Eimco clarifiers with diameters of 55 feet. Each is a half bridge,
center feed clarifier equipped with scraper arms and skimmers.
Sludge underflow from the clarifiers is combined in a wet well
equipped with a pair of pedestal type return sludge pumps each
rated at 900 GPM. The underflow rate is controlled by manually
6

mm
adjusted telescoping valves. The sludge underflow is either
mn returned to Aeration Basin No. 1 or is wasted. There is no way to
accurately set or measure the flow rate of return sludge or waste
mm sludge. The supernatant overflows the clarifier and flows by
gravity to tertiary treatment.
mm
2.4 TERTIARY TREATMENT AND OUTFALL
MR
m, Tertiary treatment consists of reaeration. The reaeration basin is
a concrete lined, in -ground basin equipped with one 20 HP floating
'' aerator. The reaerated wastewater overflows a V-notch weir where
an automatic sampler records the flow and takes effluent samples.
mm
The effluent then flows to a manhole and through two separate
outfall lines. The effluent is discharged from an end -of -pipe
outfall in the Northeast Cape Fear River.
f1
2.5 SOLIDS HANDLING
mm
The sludge underflow from the secondary clarifiers flows to a wet
MR
well where it is returned to Aeration Basin No. 1 by the sludge
ran return pumps. A pair of 100 GPM waste sludge pumps also take
suction from the sludge wet well. The sludge waste pumps are
129
normally off. Approximately once a week, the sludge return pumps
are shut off and the sludge waste pumps are engaged until the
operator judges that enough sludge has been wasted.
A

The sludge waste pumps discharge to the sludge digester. The
sludge digester was previously used as a clarifier and it is a
circular concrete basin with a diameter of 30 feet. The digester
is equipped with one 20 HP floating aerator. After digestion, the
sludge is pumped to the sand drying beds.
The sand drying beds consist of 12 separate beds. The filtrate
from the beds is pumped to Aeration Basin No. 3. The dried sludge
is manually collected from the drying beds and disposed of in a
landfill by a contractor.
2.6 WWTP INSPECTION
The existing equipment at the Guilford East WWTP was installed in
a series of steps and the age of most the equipment varies from 15
to 21 years. Hydroscience personnel conducted a thorough
inspection of the entire facility in January of 1993. This
inspection showed that most of the currently operating equipment,
including basins, pumps, aerators, piping, and other equipment, was
in good condition and would be appropriate for use in the WWTP with
the proposed increase in flaw. The few exceptions are discussed
below.
The level controller in the influent tank for the Discostrainer was
not in operation on the day of the inspection. This caused a large
portion of the flow to be discharged from the wet well overflow to
8

mm
the equalization basin without fine screening. Since the proposed
me, flow increase will increase the importance of lint removal, steps
should be taken to prevent any wastewater from bypassing the lint
PM removal step. It is possible that the existing unit could be
upgraded to accommodate the proposed flow. It is noted, however,
mm
that the basic design of the Discostrainer makes it easy to damage
and difficult to maintain.
rm, The two pumps which deliver wastewater from the equalization . basin
to Aeration Basin No. 1 are in good condition, but the automatic
`m` flow control system does not work. The flow is controlled manually
by adjusting a 6-inch gate valve on the discharge side of the
pumps. There is no way to accurately set or measure the resulting
P, flow.
mm There are two main problems with the secondary clarifiers: scum
removal, and pin floc. Small, hard plastic debris continuously
1
bypass the screening in primary treatment and end up floating on
top of the clarifiers where they clog the scum removal system. The
mm
pin floc is a separate but chronic problem with these clarifiers.
mm Pin floc are small, non -settling floc particles which overflow the
clarifier weir and cause increased suspended solids in the
effluent.
Foaming problems have been observed in three locations: in Aeration
m► Basin No. 4, in the reaeration basin, and at the manhole
9

Psi f 1
fit
immediately downstream of the V-notch weir. Foam and scum are
mmgenerated in the other aeration basins, but not at quantities which
would cause problems. Surfactants used in the manufacturing
processes are the suspected cause of this foaming.
1
Two modifications have been made since the foaming problems were
observed. First, the height of the walls in Aeration Basin No. A3
has been increased to prevent foam from overflowing this basin.
fun Second, a water spray was added to the noted manhole to knock down
foam. These modifications are expected to effectively control foam
mm
in the manhole and in Aeration Basin No.34. An additional
modification may be required to control foam in the reaeration
mm
basin.
The V-notch weir at the reaeration basin overflow already operates
ran with the water level near the top of the notch. The weir will not
be adequate for measuring effluent flow if the proposed flow
M,
increase is realized.
mm
The existing electrical system serving the WWTP is in good shape
`R except there is a mismatched circuit breaker/conductor connection.
A 1-400A/3P circuit breaker is connected to an undersized conductor
both of which serve the chlorine building which is not currently in
use. If service to this building is to be maintained, the 400 Amp
MR
circuit breaker should be replaced with a 300 Amp breaker or the
mconductors should be upgraded to accommodate 400 Amps.

3.0 REVIEW OF DATA
mm
The following discussion of data from the Guilford East WWTP is
�► intended to characterize the treatment process.
3.1 PROCESS DATA
rawf
Hydroscience personnel conducted two process surveys of the
_ Guilford East WWTP. For both surveys process data was collected
from 17 locations which are shown in Figure 1. The first survey
''' was conducted over a two day period from November 3 to November 4
of 1992. When the first survey was conducted, the equalization
basin was out of service so Sample Location No. 1 did not reflect
equalization. The second process survey was conducted on January
27, 1993. This survey was conducted during the 30-day sampling
program and the equalization basin was back in service.
m,
The results of the first and second process surveys are given in
mm
Tables 1 and 2, respectively. Note that all sample locations were
not used during either survey. Although the two surveys differed
in the parameters studied and in the locations sampled, the results
of these surveys were similar.
mm
The pH, conductivity, and temperature data were collected during
the process surveys mainly to determine how water quality varies
throughout the treatment process. The pH data show that the
11

wastewater in secondary and tertiary treatment has a consistent pH
which is just above neutral. This is a desirable pH range for
activated sludge treatment. The conductivity data show littl-
variation throughout the plant with a mean conductivity of 384
umhos/cm. This indicates that the concentration of dissolved
solids is well below levels that could interfere with treatment.
The measured water temperatures are typical of many industrial
WWTP's during the cooler months. These data show that the
relatively warm wastewater is cooled as it flows through the
facility.
The dissolved oxygen (D.O.) data show unusually high concentrations
of D.O. throughout the facility. The D.O. averaged over 7 mg/1 in
the first survey and averaged over 8 mg/1 in the second. Although
such high D.O. concentrations do not hinder treatment, they do
result in unnecessary operating costs. A minimum D.O. of 2 mg/1
should be maintained in all parts of the aeration basins, but
running the aeration system such that the D.O. is at 7 to 8 mg/1
does not increase treatment and consumes unnecessary power.
In addition to the measured D.O. data, the percent of D.O.
saturation was also calculated. The D.O. saturation concentration
for a given water temperature is taken from a standard table and
the ratio measured over saturation concentration is given in
percent. The calculated percent of saturation data show that the
D.O. in the aeration basins is consistently at approximately 80%
12

saturation. This indicates that the degree of aeration in the
aeration basins is unusually high compared to oxygen demand.
Biological activity is best quantified by measuring the rate at
which a sample of mixed liquor consumes oxygen. This rate is known
as the D.O. uptake rate. The measured D.O. uptake rates at the
Guilford East WWTP varied from 11.1 to 1.8 mg/1/hr and averaged 5.2
mg/1/hr between the two process surveys. These rates are unusually
low and reflect low levels of aerobic activity as compared to most
industrial WWTP's which average from 15 to 50 mg/1/hr.
3.2 SLUDGE MANAGEMENT DATA
Logs of process data which are kept by the WWTP operator provide
data which allow the important aspects of sludge management to be
quantified. Solids data from April to November of 1992 were taken
from the plant logs for sludge volume index (SVI), mixed liquor
suspended solids (MLSS) , and mixed liquor volatile suspended solids
(MLVSS). Table 3 shows the sludge management data from the noted
period.
SVI quantifies the density of the settled sludge under standard
conditions. A low SVI indicates good settling and a dense sludge
blanket. A high SVI can indicate settling problems. The average
SVI value for the noted period was 124 ml/g and the minimum and
maximum were 42 and 246 ml/g, respectively. These data indicate
13

inn
that this sludge is not as dense as is usually preferred, but that
it should settle without chronic problems. The SVI is increased by
the violent mixing of the surface aerators in the aeration basins.
This mixing breaks the desirable, large floc up into smaller floc
which tend to settle poorly.
The mean MLSS value for the mixed liquor was 6944 mg/1 for the
noted period. Normally, industrial WWTP sludge systems are
operated at MLSS values of approximately 3500 mg/l. Since it is
known that a large portion of the suspended solids is lint rather
than active bio-mass, the MLSS levels at this facility should be
maintained well above what is typical.
f�T
_Pir/The MLVSS data has little value unless it is compared with the MLSS
data. Therefore, the ratio of MLVSS over MLSS is also given in
Table 3. The average ratio for the noted period was 89%.
Normally, this would indicate that most of the MLSS is active bio-
mass. Since the D.O. uptake data show that there is little
biological activity, and since much influent flow bypasses the lint
removal system, it is known that much of the MLSS and the MLVSS is
lint rather than bio-mass.

f�1
3.3 LOADING DATA
The Guilford East Plant conducted an intensive 30-day sampling
program from January 28 to February 26 of 1993. Samples were taken
from five locations throughout the facility. These locations are
shown in Figure 3. The results from the analysis of influent and
effluent samples are given in Tables 4 and 5, respectively. The
data from the aeration basin, return sludge, and clarifier overflow
samples are all given in Table 6. Table 7 gives an explanation for
the titles of all the columns in Tables 4, 5, and 6. Appendix A
contains the results for all water quality analyses and Appendix B
contains the analytical reports for all the toxicity tests
conducted during this program.
The effluent flow data shows that the mean flow rate was 0.78 MGD
during the sampling program. This was slightly lower than the
long-term average flow for the WWTP which is approximately 0.84
MGD. The highest measured effluent flow was 0.959 MGD which is
lower than the permitted limit of 0.965 MGD.
Comparing the influent biological oxygen demand (BOD) data with the
effluent BOD data shows that the WWTP lowered the BOD concentration
from an average of 258 mg/1 to an average of 14.9 mg/1. This means
that 94% of the BOD is removed by the treatment process. This
removal rate is typical of an industrial WWTP. Comparing the
effluent data with the permit limits shows that the daily value
15

Poi
fogI
t,
exceeded the permitted daily maximum of 16.5 mg/1 for 7 of the 16
analyses and that the permitted average maximum of 14.9 mg/1 was
1.9
rim
ram
MEI
Mkt
higher than the permitted average maximum of 11.0 mg/l. The
percent of BOD removal will have to be increased in order to meet
the proposed daily and average BOD limits of 8.5 and 12.7 mg/1,
respectively.
Chemical oxygen demand (COD) is often a more representative measure
of organic loading for an industrial wastewater than BOD.
Comparing the mean influent COD of 777 mg/1 with the mean effluent
COD of 281 mg/1 shows that 64% of the COD is removed. This is
lower than most industrial WWTP removal rates which are typically
75%. Converting from concentration to mass loading shows that, on
average, 1833 lbs/day of COD was discharged with a maximum of 2786
lbs/day. The permitted daily and average maximums are 4750 and
9500 lbs/day, respectively. The proposed increase in flow with a
proportionate increase in mass COD loading will still result in
effluent COD loading which is well below the permit limits.
Comparing the influent total suspended solids (TSS) data with the
effluent TSS data shows treatment reduced the average TSS
concentration from 58 to 49 mg/l. This corresponds to a 16%
reduction of the influent TSS which is low compared to similar
plants. The low TSS removal rate is attributed to the pin floc
which is known to consistently overflow the secondary clarifiers.
Experience with similar plants has shown that this pin floc can
16
PEP

rum
account for a significant portion of the effluent COD and BOD.
Converting TSS concentrations to mass loadings shows that the
effluent mass loading averaged 395 lbs/day and the maximum was 835
lbs/day. The permitted average and maximum daily TSS loadings are
1035 and 2071 lbs/day, respectively. Thus, the proposed increase
m' in flow with a proportionate increase in TSS loading would still
yield effluent TSS mass loading rates well below permitted limits.
mm
Nitrate, nitrite, ammonia, total kjeldahl nitrogen, and phosphorous
are parameters which characterize nutrient loading. The data for
"' these parameters shows that influent nutrient loadings are too low
to be of concern at this plant. Furthermore, none of these
f1
analytes are limited by the Plant's NPDES permit.
3.3 WATER QUALITY AND TOXICITY DATA
In addition to loading data, the 30-day sampling program provided
useful data for characterizing water quality.
The D.O. data show that effluent D.O. concentrations were
consistently maintained above 9 mg/l. Increasing the flow is
unlikely to cause any violations of the 5 mg/1 effluent minimum on
D.O.
Some textile wastewater facilities are not able to effectively
remove soluble color which is generated in the dyeing process. The
17

tin
1=1
color data from the sampling program shows that the color of the
fowl
East wastewater is reduced from an influent mean of 900
ADMI color units (C.U.) to an effluent mean of 245 C.U. at the
unadjusted pH. This indicates effective color removal within the
facility. The effectiveness of color removal should not be
compromised by increasing the flow.
Sulfide was only measured once in the effluent at a detectable
concentration and this result was 0.76 mg/l. Converting this to a
mass loading yields 5.2 lbs/day which is well below the daily
average and maximum permit limits of 9.5 and 19 lbs/day,
respectively. Similarly, the maximum measured phenol concentration
in the effluent was 0.28 mg/1 which can be converted to 2.0
,a, lbs/day. The average and maximum permitted loadings for phenols
are 4.75 and 9.5 lbs/day, respectively. Therefore, neither sulfide
nor phenols are expected to cause non-compliance if the proposed
flow increase is implemented.

If the proposed increase in flow is realized, toxicity will be an
important issue. During the sampling period, one acute screen test
concluded that there was no acute toxicity at 100% effluent. A
chronic toxicity study was also conducted and it demonstrated that
the overall chronic value was at an effluent concentration of 18%.
Since the chronic value is so close to the current effluent
dilution of 19%, it is not surprising that chronic toxicity has
been intermittently observed with the current dilution factor.
With an increased flow, effluent dilution will be decreased and
toxicity tests will be more difficult to pass.
The Annual Pollutant Analysis for the Guilford East WWTP was
conducted on February 11, 1993 which was during the 30-day sampling
Su, program. The Analysis results showed detectable concentrations of
six inorganic chemicals: fluoride, antimony, chromium, aluminum,
copper, and zinc. Bis(2-ethylhexyl) phthalate was the only organic
compound found above detection limits besides several tentatively
identified compounds. None of these chemicals were detected at
unusual concentrations and the data generally supported the
MR
independent data obtained from the 30-day sampling program.

4.0 PROCESS DESIGN REQUIREMENTS
The purpose of the proposed upgrade is to allow the flow to
increase from 0.965 to 1.25 MGD while maintaining consistent
compliance with the new NPDES Permit. As discussed in the "Review
of Data" Section, BOD removal and toxicity reduction will be the
two primary concerns in designing the modifications which will be
required. The design requirements for each phase of the treatment
process are discussed separately.
4.1 PRIMARY TREATMENT
Lint removal must be improved to provide increased treatment at the
proposed flow. The Discostrainer which is currently used for lint
removal is already near its hydraulic capacity of 0.965 MGD and
increasing the flow to 1.25 MGD will overload this unit. More
importantly, the Discostrainer is not currently removing adequate
amounts of lint and other solids as evidenced by the amount of lint
in the sludge and by the plastic pieces causing problems in the
secondary clarifiers. The lint removal system should be upgraded
to provide sufficient hydraulic capacity and to consistently remove
a larger portion of the lint and other solids. As noted in Section
2.6, the Discostrainer is easily damaged and is difficult to
maintain in this application.
Experience with textile plants has shown that an equalization basin
20

should provide at least 24 hours of retention time to provide
adequate flow and water quality equalization. Since the capacity
of the existing equalization basin is 2.0 MG, the retention time at
the proposed flow rate of 1.25 MGD is calculated using Equation 1:
RETENTION TIME = 2.0 MG = 1.6 DAYS = 38 HOURS (1)
1.25 MGD
Based on this calculation, the existing equalization basin will be
adequate for the proposed flow.
The two pumps which deliver flow from the equalization basin to
Aeration Basin No. 1 are each rated at 750 GPM or 1.1 MGD. The
proposed flow rate of 1.25 MGD would require both pumps to be
operating most of the time and there would be no backup pump.
ram+ Since a backup pump is normally desired in case of pump
malfunction, it is recommended that a backup be provided.
1101
ran
The automatic flow control system for these two pumps must be put
back into service or replaced with a new system. The WWTP cannot
achieve maximum treatment unless the flow to the facility can be
precisely controlled and held at a steady rate.
21

fart
4.2 SECONDARY TREATMENT
There are three aspects of secondary treatment where modifications
can improve treatment: aeration volume, reduction of pin floc, and
sludge management. The optimum aeration volume is calculated using
the most conservative estimate of influent COD loading determined
by Equation 2:
COD LOAD = 800 mg * 1.25 MGD * 8.35 LBS = 8350 LBS COD (2)
GAL DAY
Note that 800 mg/1 of COD was used in Equation 2 because the mean
influent COD during the 30-day sampling program was 777 mg/l.
The required total dry mass of activated sludge is based on the
optimum food -to -mass ratio (F/M ratio). Experience with industrial
wastewaters has shown than the optimum F/M ratio is 0.2 (lbs
COD/day/lbs Sludge). This ratio is used to calculate the required
activated sludge mass using Equation 3:
8350 LBS COD
DRY SLUDGE MASS = DAY- 41700 LBS SLUDGE (3)
0.2 LBS COD/DAY
LBS SLUDGE
Since the ideal MLSS concentration for industrial wastewater
treatment is 3500 mg/1, the optimum volume of the aeration basins
22

can be calculated from Equation 4:
OPTIMUM VOLUME = 41700 LBS 106 MG/L = 1.43 MG
3500 MG/ L* 8.346 LBS/GAL
(4)
As calculated above, the optimum volume of the aeration basins is
1.4 MG. The WWTP is currently operating with a total aeration
volume of 4.0 MG. Such a high aeration volume causes unnecessary
dilution of organic loading which underfeeds the activated sludge.
Underfeeding the sludge encourages the growth of filamentous
organism which cause sludge bulking and pin floc. Other
operational conditions, such as D.O. concentration, affect the
growth of filamentous organisms, but these effects are dependent on
specific sludge management technique and wastewater characteristics
and cannot be predicted reliably.
The physical changes to secondary treatment must be accompanied by
changes in the management of the activated sludge. In order to
optimize the sludge management, the means to characterize the
sludge system must be added. This will require some method of flow
monitoring in the return sludge and waste sludge lines. Records of
important sludge system variables must be recorded and compared to
records of effluent water quality.
The secondary clarifiers must meet three design criteria to ensure
that they will have enough capacity to handle the proposed flow

design criteria requires predicted values for total flow and MLSS.
m, The total mixed liquor flow will be no more than 1.9 MGD since the
return sludge flow will be 50% of the influent flow. The MISS will

follows:

experience with textile wastewater treatment. Discussing the

1) The clarifiers should contain at least 2.0 hours of retention
time. Each clarifier has a capacity of approximately 0.2 MG,
so the total retention time is calculated using Equation 5:
rm)
Pon
RETENTION = 2 TANKS 0.2 MG/TANK = 0.21 DAYS = 5.0 HOURS (5)
1.9 MGD
With 5 hours of retention, the secondary clarifiers exceed the
minimum retention time.
2) The maximum overflow rate should be less than 450 GPD/ft2 for
textile wastewater. The overflow rate is based on the 1.25
am MGD of overflow rather than on the 1.9 MGD of mixed liquor.
Since the clarifiers are 55 feet in diameter, each has a
surface area of 2,300 ft2• Therefore, Equation 6 can be used
to calculate the overflow rate at the proposed flow:
0111
109

SURFACE LOADING =
1.9 MGD
2 TANKS * 2300 FT2/TANK

With a surface loading of 410 GPD/ft2, the secondary
clarifiers will not exceed the maximum loading rate of 450
GPD/ft2.

3) Solids loading should not exceed 15 lb/day/ft2 for textile
wastewater. The solids loading rate at the proposed flow is
calculated using Equation 7:
SOLIDS LOADING =
3500 G*1.9MGD*8.6 LB
L GAL = 12
2 TANKS * 2,300 FT2/TANK DAY FT2
LB (7)
With a solids loading rate of 12 lbs/day/ft2, the clarifiers
will not exceed the maximum of 15 lbs/day/ft2.
These calculations show that the two clarifiers can handle the
maximum mixed liquor flow after the flow is increased as proposed.
Operating the secondary treatment with the correct aeration volume
and the optimum sludge management will improve settling in the
secondary clarifiers, but the pin floc may not be eliminated.
Mixer/flocculators have been shown to eliminate chronic settling
problems in many similar facilities. A mixer/flocculator would
provide 2 minutes of mixing time, during which coagulants could be
PM
added, followed by 15 minutes of flocculation time.
4.3 TERTIARY TREATMENT AND OUTFALL
The effectiveness of the reaeration basin is unlikely to be reduced
by increasing the flow. Effluent D.O. concentrations should remain
well above the minimum 5.0 mg/l.
The V-notch weir which is used to measure effluent flow is already

foam reduction measures may be necessary.
near the maximum flow for which it is useful. This weir must be
adjusted or replaced so that it can be used to measure the higher
flows.
Foaming needs to be controlled even if the flow is not increased.
A review of the raw material purchasing records at the Plant did
not reveal any products which are noted for causing foaming
4.4 SOLIDS HANDLING
After the lint removal system is upgraded, the optimal rate of
sludge wasting should not increase above current levels even if the
PR
flow is increased. Therefore, the current solids handling system
is considered adequate for the proposed flow increase. If
additional solids capacity is necessary, or improved dewatering is
desired, the current sludge digester can be modified to serve as a
digester/thickener.

5.0 PROCESS DESIGN
The recommended modifications for achieving the process design
requirements for the Guilford East WWTP are discussed below.
5.1 PRIMARY TREATMENT
Lint and plastic removal can be increased by replacing the
sal Discostrainer and the bar screen with an Aquaguard screen system.
The Aquaguard system removes fine solids with a travelling screen
fin with 1 millimeter openings. The screen is automatically cleaned
and the screenings drop into a dumpster. Automatic dewatering of
MR
the solids is an option. The Aquaguard screen can be installed in
the wet well where the bar screen is currently located with minimal
modification to the wet well.
cal
The pumping system which delivers wastewater from the equalization
basin to Aeration Basin No. 1 should be provided with a backup pump
by one of three possible means. First, both pumps could be
replaced by higher capacity pumps. Second, the existing pumps
could be modified to increase their capacities. Third, another
pump exactly like the existing pumps could be installed in parallel
pal
with the existing pumps, or kept at the plant to allow quick
replacement after an existing pump fails. With this option, the
hydraulic capacity of the equalization basin could be utilized such
that normal production levels could continue even though one pump
27

is temporarily out of service.
The flow control system for the equalization basin effluent is the
rim final recommended modification to primary treatment. This control
system should be brought back into service or replaced.
fan
5.2 SECONDARY TREATMENT
Optimizing the operation of the aeration basins will require
changes in the flow schematic of the activated sludge system.
Since the calculated optimum aeration volume is 1.4 MG, Aeration
Basin No. 1 will provide all the necessary aeration volume. The
other three existing aeration basins should be bypassed and
abandoned.
mt+ The proposed upgrade will require modifications in the management
of the activated sludge system. The following five changes should
be gradually implemented over several months:
MR 1) The MLSS concentration should be maintained between 3000 and
3500 mg/l.
2) The sludge age should be held between 12 and 20 days.
3) Sludge should be wasted often enough to keep the MLSS between
3000 and 3500 mg/1 rather than on an preconceived schedule.
4) The flow rate of return sludge should be 50% of the influent
flow rate.
28

1� r
r
5) The D.O. should be held above 2.0 mg/1 without excessive
aeration.
In addition, records of the following should be kept: sludge age,
food -to -mass ratio, return sludge flow, waste sludge volume, and
D.O. These records should be regularly compared to effluent water
quality. A computer database would reduce the operator time and
the data loss associated with manual data logs.
p' The activated sludge cannot be accurately characterized or
controlled without the addition of flow measurement devices on the
return sludge flow and on the waste sludge flow. Optimal
management will require the installation of two flow meters: one in
the return sludge line and another in the waste sludge line.
The above recommendations for upgrading primary and secondary
rol
treatment will improve secondary settling and will reduce the
formation of pin floc. If other modifications do not eliminate the
pin floc overflowing the clarifiers, then a mixer/flocculator is
,x9 recommended. Before construction, a jar test study would be
conducted to determine the preferred coagulant. The mixer portion
will have 1,700 gallons of capacity and will be equipped with a
mixer and a means of coagulant addition if coagulants are
determined to be necessary. The flocculator section will have a
capacity of 13,000 gallons which will allow the pin floc to
coalesce into large, quickly settling floc.

5.3 TERTIARY TREATMENT AND OUTFALL
If foam reduction measures are required, then the first option is
M+ a water spray. Treated effluent would be sprayed in a coarse mist
over the areas where foam is generated. If the water spray is
insufficient, then an anti -foam agent will be required. The anti -
foam agent would then be mixed into the wastewater immediately
upstream of the areas where foam is generated.
The V-notch weir which overflows to the outfall line must be
adjusted or replaced to accommodate the proposed flow increase.
5.4 SOLIDS HANDLING
Converting the existing sludge digester to a digester/thickener
would increase the solids handling capacity of the WWTP. This
conversion would involve adding a decanter, adding a scraper arm,
rim
beds. The aerator would be turned off for 30 to 60 minutes before
ram► decanting. The decanter would then draw off the clear supernatant
and deliver it to the aeration basin. The scraper arm would keep

BIOASSAY REPORT
Ceriodaphnia Survival and Reproduction Test
(cont.)
Discussion
A Ceriodaphnia multiple concentration chronic bioassay using
Guilford Mills effluent was initiated on 02/10/93. After
approximately 48 hours, significant mortality was noted in
none of the effluent concentrations. At the end of the six -
day test period, the resulting survival and reproductive data
'.' were statistically analyzed to determine any significant
chronic effects caused by the effluent. When the mortality
data was examined via Probit, the six -day LC50 was determined
to be 22% effluent. Significant mortality (analyzed via
Fisher's Exact Test) was seen in the 25, 50, 75 and 100%
effluent concentrations. Thus, the survival NOEC was 12.5%
effluent and the LOEC was 25% effluent. Due to the extensive
mortality, only one effluent concentration (12.5%) remained
to be assessed for reproductive effects. Therefore, the data
from the control and the 12.5% concentration was analyzed as
specified in Appendix H of the EPA chronic manual (EPA/600/4-
''' 89/001), which outlines the procedure to be used when
comparing a control with one concentration. This process
resulted in a t-value of 1.814; since this value was less
than the critical t (2.552), one could conclude that there
was no significant difference in reproduction between the
control and the 12.5% effluent concentration. Therefore, the
reproductive NOEC was 12.5% effluent and the overall
chronic value (ChV) was calculated to be 18% effluent. When
the same reproduction data were subjected to point estimate
analysis (Inhibition Concentration Percentage or IC ), the
IC50 value was calculated to be 18% effluent. An IC50 of 18%
rya indicates that this is the estimated pointat which half of
the population was significantly affected in regard to
reproduction. When the reproduction data was used to
calculate the IC25, the value obtained was 14% effluent;
thus, fourteen (14) isthe percent effluent which caused one
quarter of the population to be significantly affected in
regard to reproduction.
