The effect of organic sorbent concentration on sorption kinetics

Creator:: Dolan, Mark E.
Abstract:: Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations in the liquid were sampled with time and analyzed by electron capture detector gas chromatography. Sorption was found to be a two stage process characterized by a rapid initial uptake followed by a extended...

Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

Creator:: Schaerer, Morgan A.
Abstract:: Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

Transcriptional and physiological response of Nitrosomonas europaea to inhibition by chlorinated aromatics and heavy metals

Creator:: Sandborgh, Sean C.
Abstract:: This research investigates the physiological and transcriptional responses of Nitrosomonas europaea when exposed to chlorinated aromatic compounds and heavy metals under varying environmental conditions. It was found that transcriptional responses of identified sentinel genes correlate well with nitrification inhibition. Sorption of metals to biomass was also investigated and found not...

Low Level Quantification of 1,4-Dioxane and Investigation of 1,4-Dioxane Co-Metabolism by Mycobacterium sp. 1A.

Creator:: McKeage, Kevin J.
Abstract:: 1,4-Dioxane (dioxane) is a probable human carcinogen and is often found comingled with chlorinated aliphatic hydrocarbon (CAH) contamination since dioxane is used as a stabilizer in CAH solutions. Dioxane is miscible in water, has a low K[subscript ow], low H[subscript cc], and is highly recalcitrant in the environment. The presence...

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

Molecular analysis of bacterial community dynamics during bioaugmentation studies in a soil column and at a field test site

Creator:: Li, Jun
Abstract:: 1,1,1-Tricholorethane (1,1,1-TCA), a widely used industrial solvents, is one of the most common subsurface contaminants. Transformation processes in the subsurface can result in the production of 1,1-dichioroethane (1,1-DCA) and 1,1- dichioroethene (l,1-DCE) from 1,1,1-TCA contamination, resulting in plumes of mixed chlorinated aliphatic hydrocarbons (CAHs). A butane-utilizing microorganism, strain 1 83BP,...

Hydraulic characterization and modeling of the Talking Water Garden wetland for evaluation of nitrogen removal

Creator:: Huang, Tao
Abstract:: The purpose of this research is to hydraulically characterize an engineered wetland in Albany, Oregon. The wetland receives treated wastewater from both Albany Millersburg Water Reclamation Facility (AMWRF) and ATI Wah Chang. AMWRF's water is municipal waste water. ATI Wah Chang's water comes from its nearby metal processing plant. The...

Cytokine expression in Danio rerio (zebrafish) in response to TLR-7 agonist - Imiquimod

Creator:: Paternostro, Kevin Alan
Abstract:: Utilizing Danio rerio (zebrafish) as a model organism has gained popularity recently, however a lack of research into their immune response pathways had led to the discovery of subclinical infections, and has potentially confounded results. We conducted a study to determine the cytokine expression from TLR activation in order to...

Design of a microstructured liquid-liquid separator utilizing a capillary pressure gradient

Creator:: Zoebelein, Conor M.
Abstract:: Continuous liquid-liquid two-phase separation is needed in microfluidic devices. Due to the small characteristic lengths of microreactors, phenomena such as mass transport via molecular diffusion occur within seconds. Typically, discrete slugs of an extract are created within microchannels for high specific interfacial area to achieve intensified mass transfer. A challenge...
