Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

Creator:: Isaacson, Carl W.
Abstract:: To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

Correlation of NE 1545 expression and cell size in Nitrosomonas europaea exposed to a suite of aromatic hydrocarbons

Creator:: Gilroy, Caslin Anne
Abstract:: Ammonia oxidizing bacteria, including Nitrosomonas europaea, are inhibited by aromatic hydrocarbons which can be found in wastewater treatment plants. In recent studies, changes have been observed in N. europaea cell size upon exposure to benzene, but not toluene. Additionally, NE 1545, a gene proposed to be involved in fatty acid...

The effect of coagulation conditions on floc size distribution and morphology : implications for downstream treatment processes

Creator:: Maguire, Ian R.
Abstract:: Coagulation and flocculation are commonly used in drinking water treatment as a means of destabilizing and aggregating particles and promoting adsorption of dissolved organic carbon (DOC). In practice, jar tests are used to determine optimal conditions for the removal of turbidity and DOC. However, beyond the inferences that can be...

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...

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...

Synthesis of nano-sized silicon nitride powder in microchannel reactors

Creator:: Hirayama, Michiru
Abstract:: Four types of microchannel reactors were built, using a combination of smallest alumina-tubes commercially available, for testing the feasibility of applying high-temperature microchannel reactors to the ammonolysis of SiO for producing nano-sized silicon nitride powder. The innermost tube used for feeding SiO vapor had an inner diameter (ID) of about...

Bacterial community analysis, new exoelectrogen isolation and enhanced performance of microbial electrochemical systems using nano-decorated anodes

Creator:: Xu, Shoutao
Abstract:: Microbial electrochemical systems (MESs) have attracted much research attention in recent years due to their promising applications in renewable energy generation, bioremediation, and wastewater treatment. In a MES, microorganisms interact with electrodes via electrons, catalyzing oxidation and reduction reactions at the anode and the cathode. The bacterial community of a...

Life Cycle Assessment of Biomass for Generation of energy : Case Studies of Poplar Management in the Pacific Northwest of the U.S.A.

Creator:: Vasquez Sandoval, Marcia A.
Abstract:: A Life Cycle Assessment (LCA) of the production of poplar biomass grown under four management conditions in the Pacific Northwest (PNW) of the U.S.A. was conducted. While the extraction of fossil fuels and the subsequent generation of energy have environmental impacts, the alternative of extracting poplar biomass also has impacts...

Effect of Landfill Leachate Pretreatment and SBR Operational Parameters on Nitrification Efficiency and Activated Sludge Microbial Populations

Creator:: Miller, Kierstin M.
Abstract:: A year-long, bench-scale treatability study was performed to assess whether an activated sludge sequencing batch reactor could be used to treat an influent stream of 50/50 (v/v) municipal wastewater and landfill leachate to discharge standards established by the Oregon Department of Environmental Quality. One primary obstacle that was exposed during...

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...
