Although the facility was designed to treat a combination of domestic and industrial waste, at present, the WPCF receives predominately industrial waste from the Anheuser—Busch, Inc. brewery and the Nashua Corporation. The brewery has agreed to limit the waste which it discharges as not to overload the WPCF. The plant operators have experienced considerable difficulty in operating with a varying waste load. As the facility has not received final approval on an Environmental Protection Agency construction grant, the EPA Region I Surveillance and Analysis Division was requested by Air and Water Programs Division to evaluate the brewery waste discharged to the WPCF. Water Pollution Control Facility The Merrimack WPCF located in Merrimack, New Hampshire 1.2 miles north of the Nashua (Figure 1) city line on the west bank of the Merrimack River provid s secondary treatment using a high rate trickling filter followed by activated sludge (see Figure 2). Although the facility is designed to treat a domestic flow of 2.3 mgd and an industrial flow of 2.7 mgd, the present flow into the WPCF is about 2.5 mgd which comes from Anheuser—Busch, Inc. and the Nashua Corporation. Anheuser Busch contributes 90 to 95 per cent of the flow to the WPCF. ------- Conduct of Study and Observations Under the direction of the Technical Studies Section (TSS), Sur- veillance and Analysis Division, the WPCF personnel collected hourly influent and effluent samples on February 2, 1972 (See Table 1). These samples were composited, proportional to flow, into four six—hour influent samples and four six—hour effluent samples. On February 10 and 11, 1972, the TSS used an automatic sampler to collect 24 individual hourly samples from the brewery waste stream. After the samples were analyzed for pH (Table 2 and Figure 3), they were corn— posited into two twelve—hour composites. Equipment failure, primarily due to environmental conditions, prevented concurrent sampling of the waste stream and the WPCF. Several individual grab samples were collected from the waste stream when establishing the sampling station at the brewery (MAB—l). On February 8, the automatic sampler was installed in the brewery waste stream. The sampler only collected two samples before it became clogged with a mass of material which best can be described as looking like an old mop. It had a mousey gray color with bits of yellow—green material interspersed through it. Included in the sample were several bits of paper, a drinking straw (plastic) and wood chips. When observed at 20 X, the yellow—green material appeared to be small leaves on petals of flowers (Hops would be a source of this material.); slivers of wood were observed; and the bulk of the samples was composed of a white fibrous material. A possible source of this -might be from the main veins in the hops flowers. When distilled water was added to a portion of the sample, a grey—white floc was produced. Some of this material was observed at 800 X —2— ------- and disclosed the presence of many yeast cells, small clusters of fila— inentous cellular forms, and unidentifiable debris. Mr. Sherwood, WPCF Superintendent, after being shown the mass of material stated that similar material had often caused problems in the plant. He called the Anheuser—Busch Plant engineers who observed the material and said they would investigate its origin in the brewery. All, samples were analyzed according to EPA Standard Methods at the Surveillance and Analysis Division laboratory in Needham, Massachusetts. Tables 3 and 4 present the results of these analyses. The treatment plant influent flow was measured at the main pump house and the effluent at the chlorine contact chamber (Figure 4). Although the brewery waste passes through a Parshall flume, the continuous recording equipment at the flume was not operating; therefore, the brewery waste f1o was calculated using the WPCF influent flow rate. Since the brewery con- tributes between 90 to 95 percent of the flow, the influent flow rate is representative of the brewery waste flow. Figure 5 shows the calculated flow for February 10 and 11. A temperature recorder was installed on February 8, 1972 at brewery waste flume to record the temperature of the waste (Figure 6). Due to environmental conditions and equipment failure, a continuous temperature record was not obtained. While approaching the WPCF, an apparent brewery waste odor could be detected about 100 yards from the gate. This odor was very intense inside the main pump house. —3— ------- Th weir pl.:itc oE the pr:hu try c13ri1 .Ler had pulled way Erow thu clarifier wall in places, and a large quantity of suspended solids were observed flowing over and under the weir plate. At or just below the elevation of the trickling filter distribution arm were a series of cracks in the metal exterior wall. Waste water was dripping out of the cracks and freezing on the wall. The rust on the wall indicated that the cracks had occurred some time ago. A substantial quantity of suspended solids were also observed in the effluent of the secondary clarifier and the chlorine contact chambers Discussion On April 24, 1968, Anheuser—Busch, Inc. signed an agreement with the town of Merrimack (See Appendix I) which set the approximate character- istics of the waste to be discharged by the brewery in the agreement. - Anheuser—Busch also agreed to maintain the waste pH between ..5.0 and 10.0 and not to discharge any waste which - . is of such nature as to impair the strength, durability, hydraulic, or biological capability of the town system. . . Table 5 compares the brewery waste discharged data with the values mentioned in the agreement. Although the brewery waste flow is approximately the same as stated in the agreement, the BOD concentration was up to three times the agree- ment value. The pH on February 10 and 11 varied from over two units below to almost one unit above the agreed—upon range. In addition to the violation of the range, such a large pH variation very likely will impair the biological capability of the.WPCF. —4— ------- The grey mop—like mass which clogged the sampler on February 8 could also impair the operation of the treatment plant. The WPCF removed 91 percent of the BOD and in the order of 60 percent of the suspended solids during the survey on February 2 (Table 6). Although the efficiency is acceptable for a secondary plant, the BOD of the effluent is similar to that of raw sewage discharge from a city population of 21,000. This waste is discharged near the present low point in the dissolved oxygen “sag curve” 1 of the Merrimack River, thus extending the river reach with a low dissolved oxygen. The present BOD load on the treatment plant is in excess of the design BOD capacity (See Appendix II), even though the hydraulic loading is less than one—half the design capacity. When the remaining waste in the town is tied into the WPCF, the additional BOD load will overload the facility. Table 7 presents the existing WPCF loadings. 1 Report on Pollution of the Merrimack River and Certain Tributaries • Part II — Stream Studies Physical, Chemical and Bacteriological U.S. D.I., FWPCA, 4ugust 1966 —5— ------- TABLE 1 Station Latitude Longitude Description 0 tI 0 t it NAB—i 42 49 25 71 29 04 NAB—i is at the flume where Anheuser—Busch br- ry effluent is discharged.
