NPDES Permit No. 0005266
Wilkes County
Find attached a copy of the lab results for a grab
effluent sample collected July 31, 1989, from the subject
WWTP. The sample contained 1300 mg/l of total suspended
solids and 340.ml/l of settleable solids. This sample
contained much less TSS than is often reported on the
monthly MR-1 forms. Total suspended -solids values of
2500-5000mc./l are quite often reported.
Hopefully, this information will assist in bringing
better controls on this facility. Should you need
additional information please advise.

additional nitrogen removal occurs because of better settling, but essentially no
ammonia is removed unless chemical additions to primary treatment reduce
BOD loadings to the point where nitrification can occur. An increase in total
dissolved solids can be expected. Still another method that has been proposed
involves the removal of phosphorus by contact filtration [10].
Chemical addition to primary sedimentation facilities In the simplest terms, when
aluminum or iron salts are added to untreated wastewater, they react with the
soluble orthophosphate to produce a precipitate. When lime is used, both the
calcium and the hydroxide react with the orthophosphorus to form an insoluble
hydroxyaptite. Organic phosphorus and polyphosphate are removed by more
complex reactions and by adsorption onto floc particles. The insolubilized
phosphorus, as well as considerable quantities of BOD and suspended solids,
are removed from the system as primary sludge. Adequate mixing and floccula-
tion are necessary upstream of primary facilities, whether separate basins are
provided or existing facilities are modified to provide these functions. Additions
of polymer may be required to aid in settling. A base is sometimes necessary

in low -alkalinity waters to keep pH in the 5 to 7 range with mineral addition.
Mineral salts generally are applied in the range of a 1 to 3 metal ion/J
phosphorus molar ratio (see Table 12-17 and Fig. 12-22). The exact application
rate is determined by on -site testing. It varies with the characteristics of the
wastewater and the desired phosphorus, BOD, or suspended solids removals.
Both low -lime and high -lime treatment can be used to precipitate a portion
of the phosphorus (usually about 65 to 80 percent) at pH values equal to or
less than 10. In the trickling -filter process, recarbonation is generally required
before biological treatment. In the activated -sludge process, the carbon dioxide
generated during treatment is usually sufficient to lower the pH without
recarbonation. The residual phosphorus level of 1.0 mg/L can be readily achieved
with the addition of effluent filtration facilities to which chemicals can be added.
In the high -lime system, sufficient lime is added to raise the pH to about 11

(see Fig. 12-13). After precipitation, the effluent must be recarbonated before
biological treatment.
When lime is used, the principal variables controlling the dosage are the
degree of removal required and the alkalinity of the wastewater. The operating
dosage must usually be determined by on -site testing. Although lime recalcination
lowers chemical costs, it is a feasible alternative only for large plants.
The additional BOD and suspended -solids removals afforded by chemical
additions to primary treatment may solve overloading problems on downstream
biological systems, or may allow nitrification (either seasonal or year-round,
depending on biological system designs).
Phosphorus removal in biological waste treatment Phosphorus is removed in
biological treatment by means of incorporation into cell tissue. The total amount
removed depends on the net solids produced as determined using Eq. 10-9. It can
be estimated by assuming that the phosphorus content of the cell tissue is
about one -fifth of the nitrogen content. The actual phosphorus content may
vary from one -seventh to one-third of the nitrogen value, depending on specific
environmental conditions. It has been observed that the degree of phosphorus
removal at some activated -sludge treatment plants is considerably higher than
would be predicted on the basis of the requirements for organism growth. Two
different theories have been proposed to account for this observation.
The first theory is that the removal of phosphate is brought about by
chemical precipitation, as described by Menar and Jenkins [16]. The required
conditions areas follows: (I) hydrolysis ofcomplex phosphate to orthophosphates;
(2) decreasing carbon dioxide production as the waste passes through a plug -flow
reactor; (3) an increase in pH because less carbon dioxide is being produced
and more is being removed by aeration; and (4) the development of conditions
favoring the precipitation of calcium phosphate. As noted from these conditions,
a long plug -flow reactor would be required.
The second theory is that the removal is accomplished by biological means.
It is believed that, under certain ideal conditions, the microorganisms in the
activated -sludge mixed liquor are able to remove an excess amount of phosphorus
over that required for growth [13]. This phenomenon has been termed "luxury
uptake." It is not clear if the phosphorus is incorporated (stored) within the
cell or adsorbed on the bacterial cells, or a combination of both.
Metal -salt addition to secondary treatment Metal salts can be added to the
untreated wastewater, in the activated -sludge aeration tank, or the final clarifier
influent channel. In trickling -filter systems, the salts are added to the untreated
wastewater or to the filter effluent. Multipoint additions have also been used.
Phosphorus is removed from the liquid phase through a combination of precipita-
tion, adsorption, exchange, and agglomeration, and it is wasted with either the
primary or secondary sludges, or both. Theoretically, the minimum solubility
of AlPO4 occurs at pH 6.3, and that of FePO, occurs at pH 5.3; however,
practical applications have yielded good phosphorus removal anywhere in the
range of pH 5.5 to 7.0, which is compatible with mixed -liquor organisms.

ADVANCED WASTEWATER TREATMENT 749
The use of lime or ferrous salts is limited because they produce low
phosphorus levels only at high pH values. In low -alkalinity waters, either
sodium aluminate and alum or ferric plus lime, or both, can be used to
maintain the pH higher than 5.5. Improved settling and lower effluent BOD
result from chemical addition, particularly if polymer is also added to the final
clarifier. Dosages generally fall in the range of a 1 to 3 metal ion -phosphorus
molar ratio.
Chemical polymer addition to secondary clarifiers In certain cases, such as
trickling -filtration and extended -aeration activated -sludge processes, solids may
not flocculate and settle well in the secondary clarifier. This problem may
become acute in plants that are overloaded. The addition of aluminum or iron
salts will cause the precipitation of metallic hydroxides or phosphates, or both.
Aluminum and iron salts, along with certain organic polymers, can also be used
to destabilize colloidal particles. The resultant destabilized colloids and precipi-
tates will settle readily in the secondary clarifier, reducing the suspended solids
in the effluent and effecting phosphorus removal. Dosages of aluminum and
iron salts usually fall in the range of a 1 to 3 metal ion -phosphorus molar
ratio.
Tertiary lime coagulation filtration Lime can be added to the waste stream after
biological treatment to reduce the level of phosphorus and suspended solids
(see Fig. 12-21). Single -stage process and two -stage -process flowsheets are shown
in Figs. 12-23 and 12-24, respectively. In the first -stage clarifier of the two -stage
process (see Fig. 12-24), sufficient lime is added to raise the pH above 11 to
precipitate the soluble phosphorus as basic calcium phosphate (apatite). The

The Abitibi Price permit is up for renewal. The
recommended effluent limits (based on federal guidelines)
are:
Mon. Avg. Dal. Max.
Flow (m d) 1.0
BOD (#day) 9207 17641
TSS (#7 day) 21169 31097
These limits are the same as those in the permit to
._expire July 31, 1989.
These limits allow very high concentration of
pollutants to be discharged. At the permitted flow of 1.0
mgd a BOD of 2115 mg/1 and TSS of 3729 mg/1 could be
discharged and still meet the daily maximum pounds per day
limits.
Self -monitoring data showed an average effluent BOD
during January 1989 of 356 mg/1 (range of 149 mg/1 to 647
mg/1) and for February 666 mg/1 (range of 312 mg/1 to 998
mg/1). The TSS for January averaged 2101 mg/1 (range of 320
mg/1 to 3250 mg/1) and for February averaged 2834 mg/1
(range of 650 mg/1 to 4280 mg/1). This facility's effluent
discharge on many days is equivalent to discharging aeration
basin mixed liquor but still meeting effluent limits.

Abitibi -Price has a high influent BOD, usually
4000-6000 mg/l. The influent TSS usually ranges from
300-700 mg/l, but the effluent TSS is much higher. During
January -and February 1989, the effluent TSS averages were
2101 mg/l and 2834 mg/l, respectively. The high influent
BOD is reduced but many of the biological solids produced
during the treatment processes are discharged in the Yadkin
River. Effluent TSS values average approximately 4-5 times
higher than the influent TSS.
The attached copy of a photograph taken by our office
March 27, 1987, shows the amount of solids that are
routinely discharged. After 25 hours of settling there was
approximately 25%,by volume of settled sludge. Based on an
actual flow of 1.028 mgd for the composite sampling period,
approximately 250,000 gallons of settled sludge were
discharged that day. The sample had a BOD of 560 mg/l and
TSS of 3200 mg/l and effluent limits were met.
The.discharge usually meets effluent limits and have
not been shown to be toxic. But the concern of our office
is that the receiving river may not be.protected. The
tremendous amount of discharged solids and high BOD could be
impacting the downstream aquatic community and creating
water quality problems.
In planning future stream surveys, could this stream be
considered as a study project? If downstream impacts are
occurring, the division should take action to require the
facility to correct the problems.
Should you have questions, contact our office.
