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...

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...

Examination of Immobilized TiO2 Nanoparticle Photocatalytic Treatment of Propylene Glycol with Concentrated Solar Energy

Creator:: Hammervold, Meredith
Abstract:: Airports are required by the Federal Aviation Administration to perform deicing of aircraft pavement during icy conditions. Until recently, there were no discharge controls in place and deicing fluid contaminated nearby water bodies from storm water runoff. EPA regulations now require airports to collect the deicing fluid and meet discharge...

Molecular and Kinetic Characterization of Anammox Bacteria Enrichments and Determination of the Suitability of Anammox for Landfill Leachate Treatment

Creator:: Sultana, Sharmin
Abstract:: Anaerobic ammonium oxidation (anammox) has recently appeared as a promising approach for removing nitrogen from landfill leachates because it requires less oxygen and no organic carbon compared to traditional nitrification-denitrification system, and it produces low sludge volumes, thereby reducing operating and biological sludge disposal costs by over 60%. Anammox bacteria...

Anaerobic Co-Digestion of Municipal Sludge and Fats, Oils, and Greases: Effects on Digester Performance and Microbial Community Dynamics

Creator:: Berninghaus, Ashley E.
Abstract:: The natural production of methane via anaerobic digestion (AD) is facilitated by a complex community of microorganisms, primarily bacteria and archaea, referred to as the AD microbiome. AD is growing in prominence as a solution to the disposal of food waste, sewage sludge, and the organic fraction of municipal solid...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

Creator:: Wu, Fan
Abstract:: Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

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...

The Influence of Engineered Surface Coatings on Nanoparticle Aggregation and Corona Formation: Examinations in Simulated and Real Aquatic Media

Creator:: Surette, Mark C.
Abstract:: Engineered nanomaterials (ENMs) are small anthropogenic colloids with at least one length dimension <100 nanometers. Due to the nature of their use, ENMs are being increasingly released to the environment. Yet the environmental risks posed by ENMs are unknown due to a variety challenges, including limitations with detecting and quantifying...
