  • Life Cycle Assessments for Wastewater Treatment and the Feasibility Study of Microbial Fuel Cell Technology

    Creator:
    Chien, Ku-Huan
    Abstract:
    The thesis documents research about combining the National Pollutant Discharge Elimination System (NPDES) Permit Program with the Impact 2002+ methodology to conduct a Life Cycle Assessment (LCA) for wastewater treatment processes. The LCA for the operational phase of a local wastewater treatment plant was performed and the environmental impacts caused...

  • Determination of fluorinated alkyl substances in aqueous systems

    Creator:
    Schultz, Melissa M.
    Abstract:
    Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

  • The effect of silver ions and nanoparticles on biofilms and planktonic cultures of Nitrosomonas europaea

    Creator:
    Giska, Jonathan R.
    Abstract:
    Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-­‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...

  • Determination of fluorochemicals in waste-dominated aqueous systems

    Creator:
    Huset, Carin A.
    Abstract:
    While fluorochemicals have been detected all over the world and in wastewater treatment plants, the effect of wastewater effluent on the receiving waters has not been evaluated. In the first study, the mass flow of fluorochemicals emanating from wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...

  • Essays of Land Use Changes, Open Space, and Water Pollution

    Creator:
    Hagimoto, Toru
    Abstract:
    Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate...

  • Effects of silver ions and nanoparticles on suspended cells and biofilms of Nitrosomonas europaea

    Creator:
    Barker, Leila Kelly
    Abstract:
    Silver nanoparticles are increasingly being incorporated into consumer products due to their broad-spectrum antimicrobial properties. The resulting influx of silver nanoparticles into wastewater may pose a threat to bacteria involved in biological wastewater treatment. Ammonia-oxidizing bacteria, which convert ammonia to nitrite in the first step of nitrification, are highly sensitive...

  • Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

    Creator:
    Sapp, Mandy M.
    Abstract:
    Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

  • Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

    Creator:
    Provolt, Justin J.
    Abstract:
    Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

  • Assessment of public awareness of septic systems in rural Benton County

    Creator:
    Gillett, Christopher S.
    Abstract:
    The primary objective of this study was two-fold: (1) to assess home owners awareness about issues pertaining to their septic systems; (2) and to determine the effect climate, proper care and maintenance have on septic tank performance in rural Benton County. Participants in this study were randomly selected by Benton...

  • Evaluation of copper removal from stormwater runoff using compost and Apatite II™

    Creator:
    Silvertooth, Jason R.
    Abstract:
    Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...
