This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Williams Brothers Mine is located in Mariposa County, California. Surface waters from the site drain into the south fork of the Merced River and the San Joaquin River Basin. The mine was developed in the 1980s and mined intermittently until 1996. In 1998, concerns of acidic drainage at the site arose. Effluent sampling by Engineering Remediation Resources Group (ERRG) found acid mine drainage (AMD) characterized by a pH of 3.9, sulphate concentrations of 100 mg/L and low metal concentrations of 0.074, 4.60, 1.23, 0.047 and 0.133 mg/L for Cu, Fe, Mn, Ni and Zn, respectively. The aim of this research was to evaluate passive treatment system alternatives for the mitigation of the AMD to meet water quality objectives for the San Joaquin River Basin. A bench-scale study was undertaken which consisted of 3 systems treating synthetic AMD: (1) a peat biofilter to remove dissolved metals followed by an anoxic limestone drain (ALD) to increase alkalinity and pH; (2) a sulfate reducing bacteria (SRB) bioreactor followed by an ALD, in which SRB reduce sulphate to sulfides, generating alkalinity and decreasing metal concentrations via metal sulfide precipitation; and (3) a SRB bioreactor. Synthetic AMD was produced to represent AMD characteristics observed at the site. The peat-ALD system effluent pH was 6.9 and concentrations of Fe and Cu decreased to below water quality objectives with concentrations of 0.008 and 0.06, respectively. The SRB-ALD and SRB system effluents met water quality objectives for pH and Cu, Ni and Zn metal concentrations. The effluent pH for both systems was 6.5. The SRB-ALD system reduced Cu, Ni and Zn to concentrations of 0.004, 0.016 and 0.025 mg/L, respectively. The SRB system reduced metal concentrations for Cu, Ni and Zn 0.006, 0.010 and 0.027 mg/L, respectively. Based on the bench-scale study, the pilot-scale system consisted of a combined passive treatment system containing a peat biofilter, SRB bioreactor and a limestone drain. Pilot-scale testing commenced on May 23rd, 2007. To date, some metal attenuation has been observed, with average effluent concentrations of Cu, Fe, Mn, Ni and Zn equal to

Book Synopsis 35 years of lessons learned designing, building, and monitoring passive treatment systems for mining influenced water (part 1) by : James J. Gusek
Download or read book 35 years of lessons learned designing, building, and monitoring passive treatment systems for mining influenced water (part 1) written by James J. Gusek and published by OAE Publishing Inc.. This book was released on 2024-01-29 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: While natural processes have been remediating acidic water exhibiting elevated dissolved metals for eons, engineers and scientists have been trying to mimic nature in the treatment of mining influenced water for only about 50 years. The technical community has adopted the term “passive treatment” to describe the technology. The design of passive treatment systems is based on the application of multidisciplinary engineering sciences including biogeochemistry, hydraulics, physics, microbiology, and agronomics to name a few. Consequently, there are many opportunities to not quite “get it right” in passive treatment system design, construction, and operation. Fortunately, Mother Nature can be quite forgiving and sometimes a design or operational hiccup can reveal new insights. The case histories presented in this review reflect the learning experiences of a mining engineer whose technical education barely touched on the fundamentals of passive treatment system design. Early system designs were often based on the findings of other practitioners who were gracious enough to share their knowledge at pre-internet conferences and in easy-to-understand publications. Indeed, the current state of practice of passive treatment design rests on the shoulders of a few brilliant pioneers, most of whom are still with us. This review continues the sharing tradition. The common thread among the mini-case histories discussed is that most are from bench- and pilot-scale testing programs, which reinforces the benefits of small-scale testing as an economical way to accumulate valuable lessons learned experience with minimum risk. Key takeaways from the lessons learned by this author are: ● Biochemical reactors (BCRs) can be overloaded, but only for a short time to avoid permanent harm to the microbial community. ● Other metal removal processes can substitute for sulfate reduction in overloading situations but the beneficial effects may be reversible. ● Media material substitution risk in full scale construction can be lessened if bench or pilot data is available. ● BCRs are feasible in cold climates. ● The age of woody material (fresh vs. moldy) in BCR media is inconsequential. ● Allow plants to grow on BCR surfaces with caution. ● Excessive aluminum concentrations do not cause BCR media to plug. ● Metal adsorption to manganese oxide coatings may be a viable alternative to sulfide precipitation in BCRs. ● Mixing bypassed mining influenced water with BCR effluent may offer benefits in a freshet. ● A test failure may be due to an improper design and should not condemn the passive treatment concept. ● In final design and construction, avoid deviating from the bench- or pilot-scale test conditions.

Book Synopsis Passive Treatment Systems for Acid Mine Drainage by : K. L. Ford
Download or read book Passive Treatment Systems for Acid Mine Drainage written by K. L. Ford and published by . This book was released on 2003 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passive treatment systems provide an alternative method for removing metals from acid mine drainage. There are several types of passive treatment systems; they may be used on their own or in combination to treat difficult effluents. The type of system selected is dependent upon the chemistry of the acid mine drainage and the flow of the discharge, as well as State and Federal regulations. Passive treatment systems do not require power and are less expensive than active treatment systems. They also require less maintenance, which makes them advantageous in remote locations.
Book Synopsis Passive Treatment of Acid Mine Drainage with Sulphate Reducing Bacteria by : Ryan Andrew Peterson
Download or read book Passive Treatment of Acid Mine Drainage with Sulphate Reducing Bacteria written by Ryan Andrew Peterson and published by . This book was released on 2013 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research was completed to assess passive treatment methods for mitigation of acid mine drainage (AMD) at a former mine site in British Columbia. The objectives were to determine if suitable passive treatment methods were available, and if concentrations of Cd, Zn, and other key contaminants in groundwater could be reduced to below regulatory standards during bench-scale testing. Biological treatment with sulphate reducing bacteria (SRB) was selected, and bench-scale treatment testing was conducted using columns amended with low cost organic sources. Removal of more than 99% Cd, 93% Co, 96 % Cu, 86% Ni and 98% Zn was observed, resulting in metals concentrations in treated effluent consistently lower than applicable groundwater standards. Sustainability attributes of treatment with SRB and the potential to recover valuable metals are discussed, and recommendations for further testing and implementation are provided. Keywords : acid mine drainage, passive treatment, sulphate-reducing bacteria, bioreactor.

Available in PDF, EPUB and Kindle. Book excerpt: The report develops an approach for reliably evaluating the impact of proposed water pollution abatement plans for a river basin. A water quality simulation model is developed which has the capability of routing acid mine drainage through a river basin. A computer procedure providing for the optimization of alternatives is also developed. The simulation model is used to evaluate alternatives within a larger framework that involves optimization. The approach is to use the simulation as a method of impact assessment which is manipulated by optimization logic. Thus the simulation can be used in two ways: as a stand alone model or as an adjunct to optimization. The Tioga River Basin in Pennsylvania has been chosen as a case study.

Available in PDF, EPUB and Kindle. Book excerpt: An ongoing concern is acid mine drainage (AMD) from abandoned sulphidic mines in the Sydney coalfield, which threatens local water bodies and fishing industries if left untreated. This work focuses on evaluating the performance of two semi-passive treatment systems at the Neville Street facility that treat this AMD, which is acidic and contains heavy metals such as iron, manganese, and aluminum. These treatment systems include caustic soda addition, aeration cascades, settling ponds, and constructed wetlands. Current monthly sampling by a local government agency may or may not represent worst-case scenarios as sampling may not coincide with conditions that could impact performance, such as peak loading. This work was divided into three research objectives: (1) characterize system performance during peak loading, (2) statistically evaluate treatment performance, and (3) develop a treatment performance model of the constructed wetlands. Analysis of sampling data during peak loading events indicates that both systems are effectively removing iron from the mine water with effluent readings meeting federal and provincial guidelines. However, inlet iron concentrations have been increasing over time for both systems; thus, exceedances of guideline limits could become a concern in the future. Due to newly adopted federal and provincial guidelines for manganese and sulphate, exceedances of these guideline limits have been or are likely to become a concern in the near future. Modeling of wetland treatment performance using a modified tanks-in-series (TIS) model revealed the necessity for site-specific calibration of model constants. Areal rate constants at 20 °C for iron were developed for both systems based on design and average operating conditions. The design areal rate constants at 20 °C for the two systems were 2,325 m/year and 1,380 m/year; the average areal rate constants at 20 °C were 1,930 m/year and 560 m/year.

Book Synopsis Evaluation of Passive Systems for the Treatment of Mine Drainage by : Heath Roscoe
Download or read book Evaluation of Passive Systems for the Treatment of Mine Drainage written by Heath Roscoe and published by . This book was released on 1999 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid Mine Drainage (AMD) is a serious environmental problem and the focus of a great deal of research. Passive treatment systems associated with wetlands and Anoxic Limestone Drains (ALDs) provide a low-cost, low-maintenance treatment in contrast to continuous chemical metering. The ALD adds alkalinity to the water allowing for a more rapid formation of iron precipitates. The abiotic oxidation ponds associated with these systems are expected to precipitate about 10-20 g/sq m-day of iron. The focus of this research is to evaluate two different ALD passive treatment systems in order to find ways to improve the efficiency of the abiotic oxidation of ferrous, thereby reducing the amount of land area required to treat the discharge. The two systems evaluated differed in that one system is a channel system, while the other is a series of ponds. The channel system has a large excess of alkalinity while the pond system has net mineral acidity. The study of the systems was conducted over a one-year period starting in January 1998 and ended in January 1999. The evaluation of each system included monitoring the chemistry and using MINTEQA2, a chemical equilibrium computer program to assist in the analysis. Of all the major cations in solution, ferrous is the only one that is removed in the system.
