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...

Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

Creator:: Schrlau, Jill E.
Abstract:: The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...

Transformation of Carbon Tetrachloride and Chloroform by Trichloroethene Respiring Anaerobic Mixed Cultures and Supernatant

Creator:: Vickstrom, Kyle E.
Abstract:: Carbon tetrachloride (CT) and chloroform (CF) were transformed in batch reactor experiments conducted with anaerobic dechlorinating cultures and supernatant (ADC+S) harvested from continuous flow reactors. The Evanite (EV-5L) and Victoria/Stanford (VS-5L) cultures capable of respiring trichloroethene (TCE), 1,2-cis-dichloroethene (cDCE), and vinyl chloride (VC) to ethene (ETH) were grown in continuous...

The Vadose Zone as a Hyporheic Carbon Source : A Look at Temporal Trends in Hyporheic Zone pCO₂

Creator:: Brandes, Jason B.
Abstract:: Stream chemistry studies conducted in the forested Watershed 1 of the HJ Andrews Experimental Forest show a contribution of CO2 from the hyporheic zone. Hyporheic CO₂ concentrations, measured as pCO₂, have a seasonal trend as well as a responsiveness to storm events. Concentrations are highest at the end of the...

The Influence of Stormwater Water Quality on the Adsorption of Copper and Zinc onto Five Different Sorbents

Creator:: Kanalos, Casey A.
Abstract:: Best Management Practices (BMP) are widely used as a method for stormwater volume control in urban areas to prevent an overload of water on receiving water bodies and treatment facilities. BMPs ability to treat stormwater has gone under critical review in the last few decades, and their performance varies both...

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,...

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...

The Effect of Oxygen and Salinity Conditions on Soluble Metabolic Product Formation by Methylomicrobium buryatense 5GB1

Creator:: Cameron, Marina R.
Abstract:: Methanotrophic bacteria are promising means of producing value-added products as they have the ability to transform methane under atmospheric temperature and pressure. Efforts to develop methanotrophs to produce value-added products are hoped to incentivize a decrease in methane flaring operations. The data collected during this study was used to inform...

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...

RANS and LES predictions of turbulent scalar transport in dead zones of natural streams

Creator:: Drost, Kevin J.
Abstract:: Natural stream systems contain a variety of ﬂow geometries which contain ﬂow separation, turbulent shear layers, and recirculation zones. This work focuses on streams with dead zones. Characterized by slower ﬂow and recirculation, dead zones are naturally occurring cutouts in stream banks. These dead zones play an important role in...
