Experimental and numerical analysis of transport in saturated heterogeneous media

Creator:: Harrington, Stephanie J.
Abstract:: The conventional advection-dispersion equation cannot adequately describe all processes driving solute transport in heterogeneous systems. This dissertation focuses on the individual influences of both chemical (Chapter 2) and physical processes (Chapters 3 and 4) which affect solute transport. In Chapter 2 we analyzed uranium transport in natural sediment using the...

Exploring the Anaerobic Co-digestion of Food Waste, Brewery Waste, and Fats, Oils, and Greases through Biomethane Potential Testing and Response Surface Methodology

Creator:: Liberman, Madalyn R.
Abstract:: Food waste (FW), brewery waste (BW), and fats, oils, and greases (FOG), are prevalent waste streams in municipalities across the country, particularly in the Pacific Northwest (PNW). Anaerobic digestion (AD), the microbial-mediated transformation of organic waste into methane-rich biogas, offers a sustainable, energy-generating, waste management solution for these wastes. Anaerobic...

Cometabolism of 1,4-Dioxane and Chlorinated Aliphatic Hydrocarbons by Pure Cultures of Rhodococcus rhodochrous 21198 and Mycobacterium ELW1 and in Groundwater Microcosms Fed Isobutane and Isobutene as Growth Substrates

Creator:: Krippaehne, Krysta J.
Abstract:: 1,4-dioxane and chlorinated aliphatic hydrocarbons (CAHs) such as trichloroethylene (TCE) and 1,1-dichloroethene (1,1-DCE) are hazardous compounds commonly found in soil and groundwater. Bioremediation through aerobic cometabolism is a potential option for the remediation of these contaminated sites. The purpose of this study was to examine the use of different primary...

Metabolic uncoupling of Shewanella oneidensis MR-1, under the presence of excess substrate and 3,3’,4’,5 tetrachlorosalicylanilide

Creator:: Saini, Gaurav
Abstract:: Dissociation between catabolism and anabolism, generically termed “metabolic uncoupling”, has been studied for aerobic cultures of Shewanella oneidensis MR-1. Under conditions promoting metabolic uncoupling, the cell yield diminishes while the substrate utilization rate remains largely unchanged. The effects of excess substrate conditions and TCS addition on the metabolism of pyruvate...

Epistemic Practices in Civil and Environmental Engineering Among Students, Faculty, and Practicing Engineers

Creator:: Babikoff, Travis J.
Abstract:: The epistemic practices that make up engineering are poorly understood and there is a lack of empirical research on this topic. Characterizing the epistemic practices of engineering students, faculty, and professionals is critical to creating effective curriculum that aids in developing student’s epistemic practices. Doing so allows us to better...

Effects of Step-Wise Acclimation versus Shock Loading on the Performance of Anaerobic Co-Digestion of Fats, Oils, and Greases

Creator:: Berninghaus, Ashley E.
Abstract:: Anaerobic digestion is a microbially mediated process by which organic matter is decomposed in the absence of oxygen. The end products of anaerobic digestion include treated sludge and biogas, a mixture of methane and carbon dioxide, which can be recovered and used for energy generation. The majority of wastewater treatment...

Co-treatment of Municipal Wastewater and Landfill Leachate in an Activated Sludge Sequencing Batch Reactor

Creator:: Bushee, Gavin A.
Abstract:: A year-long bench-scale treatability study was performed to assess the feasibility of using an activated sludge sequencing batch reactor (SBR) to treat a mixture of domestic wastewater and landfill leachate. A 50/50 (v/v) of domestic wastewater and landfill leachate was treated in a 1 L SBR operated on a 12...

Visualization and characterization of biofilm spatial distribution in porous media using x-ray computed microtomography

Creator:: Iltis, Gabriel C.
Abstract:: This work focuses primarily the development of methods for imaging microbial biofilms in opaque porous media using x-ray computed microtomography (CT). Two methods for evaluating biofilms in porous media are presented. The first focuses on the addition of silver-coated, hollow glass microspheres to a biofilm-containing micro-model. The silver-coated microspheres affix...

Kinetic and molecular effects of sulfate reduction on a dechlorinating culture under chemostat growth conditions

Creator:: Berggren, Dusty Rose V.
Abstract:: Chlorinated ethenes are common groundwater contaminants that may be treated through in-situ bioremediation. Relationships between the reducing environment, available electron donors and acceptors, reaction kinetics, and microbial community composition must be further understood to successfully engineer remediation schemes in the complex subsurface environment. This thesis work investigated the effect of...

Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

Creator:: Fullmer, Lauren
Abstract:: Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...
