Craft Progress Report Project A-1923 Sponsored by Coastal Plains Regional Commission 215 East Bay Street Charleston, S. C. 29401 The Engineering Experiment Station Georgia Institute of Technology Atlanta, Georgia 30332 May 17, 1977 FILTRATION OF WASTE STABILIZATION POND EFFLUENTS .Introduction The objective of the subject work is to obtain field data on the general applicability of sand, authracite, and mixed media filters for upgrading the effluent from ponds to bring them in compliance with federal regulations concerning suspended solids. Waste stabilization ponds are widely used in smaller comflunities, and have generally been found to be acceptable in terms of efficiency, cost, and upkeep. The promulgation of new federal regulations has produced a need for lower effluent suspended solids content than is usually obtained. As it is wholly unrealistic to consider abandonment of ponds as a treatment method, means for producing better pond effluents are needed. Filtration is a general procedure for separating particulate matter from liquids, and is widely used in water treatment and, to a much lesser extent, in wastewater treatment. While there is seemingly no 'a priori reason that filtration of pond effluents will not work, the technique has not yet been demonstrated, and consequently no engineering data is available. The project has been undertaken to provide a demonstration and appropriate data. Equipment Acquisition The major item of concern has been (and is) the filter and its accoutrements. Specifications were drawn for the desired equipment, which included a complete set-up mounted on a trailer and including a generator for operation without regard to availability of an external power source. All bids were far too high, as the cost of the trailer was much higher than previously estimated. Through a concerted effort and with the splendid cooperation of the Georgia State Agency for Surplus Property we obtained an eminently satis- 1 factory trailer. Although it was manufactured in 1954, the massive frame of this old surplus Air Force trailer is in excellent condition. Repairs were required on the brakes and lights, and all tires needed replacement, but when all costs are added, the total is less than 10% of the cost of a new trailer. A portable generator was also obtained from this same source, and again at a small fraction of the cost of a new unit. The initial bids were all rejected and new bids were requested. The low acceptable bid was submitted by Davco-Defiance, Thomasville, Georgia and the order was placed. This supplier has so far been most cooperative in making slight changes in layout and design of the filter unit, and a very good result is expected. Davco-Defiance has also agreed to mount the filter and generator on our trailer, so that the unit will be essentially ready to run when delivered. The initial delivery date was scheduled to be the first of May, but the rebidding caused delay. Presently the filter is to be completed May 12, with mounting and other final details to require 2 or 3 more days. The project director is planning to inspect the completed unit at Thomasville May 19. Site Selection With the assistance of representatives of the Georgia State Environmental Protection Agency, some 20 ponds were selected for consideration. The main technological aspects sought were that the pond is in "normal" operating conditions and that it is representative of a larger number of ponds. Imposed on these factors is the very practical matter of accessibility of the pond so that the large, heavy (about 32,000 lbs) filter unit can be moved in. This latter consideration has eliminated those locations whose approaches include a narrow, rutted, steep incline, or (very frequently) a small bridge of unknown, but suspect capacity. Other practical limitations, particularly in the Atlanta area, have eliminated other sites. Houses are located quite 2 close to some of these ponds and the noise of a gasoline engine powered generator running all night would obviously be a nuisance. Candidate locations in the Atlanta area were inspected with particular care, as a situation close to Georgia Tech was sought where initial start- up could be accomplished and data collected. If any problems arise, prox- imity to our home base will be very important as a matter of convenience and travel time. A two-stage pond in Gwinnett County has been chosen for the initial site. It is located about 30 miles from the Tech campus, but is less than 2 miles from Interstate 1-85. Paved roads lead to within a few feet of the fence surrounding the pond. There is obviously an advantage to a two-stage operation, as it will be possible to withdraw effluent from each stage, and thereby provide two sets of data from a single location. This pond receives no industrial wastes, and serves only a residential area and a grammar school. Plan of Operation The filter is expected to be delivered to the Gwinnett County site before the end of May, and operations will begin immediately. Samples will be collected at frequent intervals and transported to Tech for analysis. Analytical data collected by the county Will also be obtained and utilized. It is not possible at this time to determine just how long it will be necessary to work at the initial location, but it is estimated to be about 6 weeks. If things work out in an easy fashion, the time could be somewhat less. The second location for operation is at Monroe, Georgia, where the multi-cell pond arrangement includes aerators in the first cell. Subsequent locations will be toward the south, with the expectation of eventually reaching the Brunswick area. 3 GEORGIA INSTITUTE OF TECHNOLOGY ATLANTA, GEORGIA 30332 OFFICE OF THE COMPTROLLER July 24, 1980 Mr. McIver Watson, Program Officer Costal Plains Regional Commission 215 East Bay Street Charleston, S.C. 29401 Dear Mr. Watson: Enclosed is the Final Fiscal Report for Grant No. 10740003 covering the period January 1, 1979 through May 1, 1930.

Accepted 3 August, 2012 The objective of this research is to evaluate the performance of macrophyte waste stabilization pond system for municipal wastewater collected from Taxila (Pakistan). A model of macrophyte waste stabilization pond system was operated for six trials with each trials comprising different detention times that is 3, 5, 7 and 10 days, respectively. For the treatment, locally available macrophyte (water hyacinth) was used. To evaluate the performance of macrophyte waste stabilization pond, BOD5, TDS, TSS, COD, faecal coliform and Nitrogen for the effluent from pond model were measured at each detention time of every trial after ensuring steady state conditions. The influent values of same parameters have been measured at the start of each trial as the wastewater sample was collected from the municipal sewer. The average reduction of effluent value of each parameter varies from 30 to 48%, that is BOD5 (48%), TDS (31%), TSS (30%), COD (42%), faecal coliform

  • Reengineering of an Obsolete Sewage Treatment System
    water Article Transformation of Waste Stabilization Ponds: Reengineering of an Obsolete Sewage Treatment System Silvânia Lucas dos Santos 1 and Adrianus van Haandel 2,* 1 Department of Civil Engineering, Federal University of Rio Grande do Norte, 59.078-970 Natal, Brazil; [email protected] 2 Department of Civil Engineering, Federal University of Campina Grande, 59.429-350 Campina Grande, Brazil * Correspondence: [email protected]; Tel.: +55-83-99133-0196 Abstract: Waste Stabilization Ponds (WSPs) are commonly used for sewage treatment. These systems are composed of a series of ponds: (1) anaerobic ponds, (2) facultative ponds, and (3) maturation ponds. WSPs generally produce good-quality effluent in terms of organic matter and pathogen removal, but their application has disadvantages. The most serious disadvantages are a long retention time, the release of biogas, and the impossibility of removing nutrients. A promising alternative to the use of WSPs is replacing the anaerobic pond and facultative pond with an upflow anaerobic sludge blanket (UASB) reactor, with the advantages of greatly reducing the retention time and the biogas capture. The post-treatment ponds of the UASB reactor effluent involve oxygen production and the biological consumption of carbon dioxide, which raises the pH. An experimental investigation showed that it is possible to use polishing ponds in a sequential batch regime instead of continuous flow. This modification accelerates the decay of pathogens and accelerates the increase in pH, which, in turn, facilitates the removal of nitrogen and phosphorus. This produces a good-quality effluent with low concentrations of biodegradable organic material, nutrients, and pathogens. This good- Citation: dos Santos, S.L.; quality effluent is obtained in a system without energy consumption or auxiliary materials and with van Haandel, A.

  • Kennecott Groundwater Permit Pipelines
    GROUND WATER QUALITY DISCHARGE PERMIT UGW450012 STATEMENT OF BASIS US Magnesium LLC Rowley, Utah April, 2020 Introduction The Director of the Division of Water Quality (Director) under the authority of the Utah Ground Water Quality Protection Rules1 (Ground Water Rules) issues ground water discharge permits to facilities which have a potential to discharge contaminants to ground water2. As defined by the Ground Water Rules, such facilities include milling and metallurgical operations and ponds and lagoons whether lined or not. As defined in Utah Admin. Code R317-6-1, US Magnesium is considered an existing facility because it was under operation before February 10, 1990. The Ground Water Rules are based on an anti- degradation strategy for ground water protection as opposed to non-degradation; therefore, discharge of contaminants to ground water may be allowed provided that current and future beneficial uses of the ground water are not impaired and the other requirements of Rule 317-6-6.4.C are met4. Following this strategy, ground water is divided into classes based on its quality5; and higher-quality ground water is given greater protection6 due to the greater potential for beneficial uses. The Director has developed permit conditions consistent with Rule 317-6 and appropriate to the nature of the wastewater, facility operations, maintenance, discharge minimization technology7 and the hydrogeologic and climatic conditions of the site, to ensure that the operation not contaminate ground water. Basis for Permit Issuance Under Rule 317-6-6.4A, the Director may issue a ground water discharge permit for an existing facility if: 1) The applicant demonstrates that the applicable class TDS limits, ground water quality standards and protection levels will be met; 2) The monitoring plan, sampling and reporting requirements are adequate to determine compliance with applicable requirements; 3) The applicant utilizes treatment and discharge minimization technology commensurate with plant process design capability and similar or 1 Utah Admin.

Tragically, the collective federal and state agency aversion for environmental remediation has not changed since the 1949 Atomic Energy Commission (AEC) designated National Reactor Test Station – now called the Idaho National Laboratory - in south-eastern Idaho desert as another nuclear sacrifice zone. The underlying Snake River Aquifer was perfect for providing the massive water needs for what the AEC and its successor Department of Energy required for the 52 reactors that were built/tested at the site. In the early years, the aquifer was both the source for reactor cooling water but also the place to inject the highly radioactive hot waste water that could not be dumped in percolation ponds for fear of worker exposure.
