Available in PDF, EPUB and Kindle. Book excerpt: Constructed wetlands have been shown to be effective in treating various types of wastewater. One type, Acid Mine Drainage (AMD), is characterized by high acidity, heavy metals, and sulfate. Five Constructed Wetlands, Friar Tuck, Tecumseh, and Midwestern in southwestern Indiana, and Simco and Wills Creek wetland in Ohio, were studied to determine their treatment efficiencies for sulfate and metal removal. Sulfate Reduction by microorganisms in constructed wetlands can remove sulfate and dissolved metals, and can generate alkalinity. Approximately 100 water samples and 50 soil samples were taken during the winter and summer seasons at the five wetlands and analyzed for sulfate and metal concentrations, sulfur isotope values, pH, Eh, and conductivity. Resulting data indicates that sulfate reduction is occurring at all five wetlands, but varies in degrees of treatment effectiveness. The Friar Tuck wetland shows minimal evidence of sulfate reduction, with dilution being the main remediation mechanism. A small volume of AMD is being overwhelmed by numerous freshwater inputs resulting in a significant improvement in water chemistry due to this dilution. The Tecumseh wetland shows little change in influent/effluent sulfate and sulfide values suggesting that treatment of the influent wastewater by sulfate reduction was ineffective for both sampling seasons. The Midwestern wetland for the summer season shows a significant increase in water sample d 34 S, from -5.03 permil to +0.27 permil with a corresponding drop in sulfate concentrations from 1740 ppm to 831 ppm, demonstrating successful sulfate reduction and wastewater treatment. However, the winter season sampling showed no change in d 34 S, indicating only minor sulfate reduction, but sulfate concentrations still fell from 1740 ppm to 831 ppm, indicating an additional sulfate removal process. The Wills Creek wetland shows little change in influent/effluent sulfate concentrations and sulfur isotope values suggesting that sulfate reduction is inactive for both sampling seasons. The Simco wetland was flooded due to beaver constructed damns during our winter sampling and accurate data were not obtained. Summer water sample data show a significant increase in d 34 S, from -3.58 at the influent to +6.26 at the effluent and a corresponding decrease in sulfate concentrations from 640 ppm to 290 ppm, demonstrating successful sulfate reduction trends.

This book was released on 2017-08-29 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Cost Wastewater Bioremediation Technology: Innovative Treatment of Sulphate and Metal Rich Wastewater provides users with an authoritative guide on the technologies, processes and considerations needed for the treatment of Sulphate and Metal rich wastewaters. In this book, the authors not only explain the associated technologies, but also provide suitable alternatives to commercial treatment in terms of performance and cost effectiveness. As enormous quantities of sulphates and metal-rich contaminates are released into the environment each year, the technologies noted in the book provide the most eco-friendly, low cost and efficient alternatives available. - Covers the efficiency of treatment in terms of scale, efficiency and effectiveness of different bioremediation technologies for wastewater remediation - Discusses the economics of treatment and the development of suitable alternatives in terms of performance and cost effectiveness
