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...

Aerobic Cometabolism of cis-Dichloroethylene, 1,1,1-Trichloroethane, and 1,4-Dioxane by Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads that Co-Entrapped Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Column Studies

Creator:: Bailey, Kestrel
Abstract:: CisCis-Dichloroethylene (ciscis-DCE), 1,1,1-Trichloroethane (1,1,1-TCA), and 1,4-Dioxane (1,4-D) are chlorinated solvents used as solvents and degreasers in industrial cleaning agents that have become common groundwater contaminants. To develop an effective treatment method for these compounds, polyvinyl alcohol (PVA) and sodium alginate (SA) hydrogel beads were co-entrappcapsulated with Rhodococcus rhodochrous Strain ATCC...

Evaluation in a Physical Aquifer Model the Long-Term Performance of a Permeable Reactive Bio-Barrier Packed with Co-encapsulated Gellan Gum Beads for the Bioremediation of Chlorinated Compounds and Co-Contaminants

Creator:: Wortkoetter, Jacob
Abstract:: Chlorinated solvents are a class of widespread groundwater contaminants that are toxic, carcinogenic, and difficult to remediate at low concentrations. 1,4-dioxane, a suspected carcinogen, is often a co-contaminant found in mixtures of chlorinated solvent plumes. In-situ bioremediation methods of degrading these chemicals through aerobic cometabolism have shown promise. Permeable Reactive...

Aerobic Cometabolism of 1,4-Dioxane and cis-Dichloroethylene by Gellan Gum and Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads Co-Encapsulated with Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Batch, Column, and Toxicity Studies

Creator:: Conway, Sean P.
Abstract:: 1,4-Dioxane (dioxane) and cis-dichloroethylene (cDCE) are compounds commonly found in industrial cleaning and degreasing agents that are frequently present as groundwater contaminants. In an effort to develop a more effective treatment method for these compounds, hydrogel beads were fabricated with either gellan gum or a combination of polyvinyl alcohol (PVA)...

Ultrafiltration Membrane Fouling in Side-stream Aerobic Granular Sludge Membrane Bioreactor

Creator:: Yang, Zhengjian
Abstract:: The integration of low-pressure membrane filtration and aerobic granular sludge (AGS) reactor leads to a novel environmental biotechnological process with strong potential to overcome membrane fouling and demonstrate excellent wastewater treatment performance. However, membrane fouling mechanisms in the AGS based membrane bioreactor (MBR) are lack of systematic elaboration. In the...

Optimization of Geologic Carbon Sequestration: Effect of Flowrate on Nonwetting Phase Connectivity

Creator:: Davis, Brittany R.
Abstract:: Atmospheric carbon reduction is arguably the most crucial facet among efforts to mitigate climate change. The Fifth International Panel of Climate Change report emphasizes a worldwide goal of maintaining global temperature elevation less than 1.5°C above pre-industrial temperatures. This report also acknowledges without the proper utilization of counteractive emission strategies...

Optimization of Wastewater Sampling and Concentration Methods to Accurately Detect and Quantify SARS-CoV-2 in Varying Scales of Catchment

Creator:: George, Andrea D.
Abstract:: At the beginning of the COVID-19 pandemic, the world was unprepared for such a massive challenge to global health. Individual testing kits and personal protective equipment were scarce. There were minimal ways to track the rapid spread of the disease, until researchers discovered that SARS-CoV-2, the virus that causes COVID-19,...

Sediment Deposition Characteristics in Shallow Saturation Excess Overland Flow with Application to Bioswales and Construction of a Novel Bioswale Design for Improved Contaminant Removal from Stormwater

Creator:: Wells, Jacqueline R.
Abstract:: Over the last two decades, urban stormwater management has grown to include green infrastructure, such as bioswales. These systems were primarily designed to mitigate hydraulic peaking during rainstorms but were also found to remove particulate and dissolved contaminants. However, little is known about the fate of these particulate contaminants after...

The Effects of Naturally Occurring Biofilms in Rapid Small Scale Column Testing of Sorbents for the Removal of Copper, Zinc, Nutrients, and Organic Carbon form Stormwater

Creator:: Rodman, Kelly E.
Abstract:: This project determined how the presence of environmental biofilms on sand, granular activated carbon and biochar affected the sorption capacity and desorption quantity of copper, zinc, nutrients and organic carbon from stormwater. These contaminants have harmful and toxic environmental impacts on aquatic life, can lead to eutrophication of surface waters,...

Cometabolism of 1,4-Dioxane and Chlorinated Aliphatic Hydrocarbons by Rhodococcus rhodochrous ATCC 21198 and Coencapsulated with a Slow-Release Substrate in Microcosm and Column Studies

Creator:: Bealessio, Alisa D.
Abstract:: Mixtures of 1,4-dioxane (1,4-D) and chlorinated aliphatic hydrocarbons (CAHs) are common and hazardous groundwater contaminants that can be challenging to address with traditional remediation strategies. Bioremediation through aerobic cometabolism has the potential to be an effective in-situ treatment strategy for these contaminants. Rhodococcus rhodochrous strain ATCC 21198 is capable of...
