Removal Of Trace Organic Compounds In Domestic Wastewater Using Recirculating Packed-Bed Media Filters, Brittani Nikole Perez
Removal Of Trace Organic Compounds In Domestic Wastewater Using Recirculating Packed-Bed Media Filters, Brittani Nikole Perez
Masters Theses
Pharmaceuticals and personal care products (PPCPs) are commonly detected in the environment resulting from their survival from conventional wastewater treatment systems. More information is needed about the fate and transfer of these trace organic compounds in domestic wastewater and their associated risks so that efficient strategies for their removal can be developed for both large/small scale treatment systems. This study aimed to determine whether onsite wastewater treatment systems were capable of providing PPCP removal, in addition to quantifying different forms of removal (biodegradation/sorption). A column study was constructed to determine the removal efficiencies of 3 target PPCPs, endocrine disrupting compound …

Development Of A Novel Enzymatic Pre-Treatment For Lignocellulosic Biomass, Melissa Robins, Jenna Rickus
Development Of A Novel Enzymatic Pre-Treatment For Lignocellulosic Biomass, Melissa Robins, Jenna Rickus
The Summer Undergraduate Research Fellowship (SURF) Symposium
Biofuels, fuels derived directly from living matter, present a renewable and environmentally friendly alternative to petroleum based fuels. Bioethanol produced from low input energy crops or agricultural waste is a promising fuel source because it does not interfere with the human food supply chain and the ethanol produced can be blended with gasoline. These potential sources of bioethanol are not yet commercially viable due to a polymer called lignin present in the plant’s cell wall which impedes the conversion of cellulose to glucose and the eventual fermentation of glucose to ethanol. Developing new methods for the pretreatment of lignocellulosic biomass …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Lignin, a complex organic polymer, is a major roadblock to the efficiency of biofuel conversion as it both physically blocks carbohydrate substrates and poisons biomass degrading enzymes, even if broken down to monomer units. A pretreatment process is often applied to separate the lignin from biomass prior to biofuel conversion. However, contemporary methods of pretreatment require large amounts of energy, which may be economically uncompelling or unfeasible. Taking inspiration from several genes that have been isolated from termites and fungi which translate to enzymes that degrade lignin, we want to establish a novel “enzymatic pretreatment” system where microbes secrete these …
Transformation Of Swine Manure And Algal Consortia To Value-Added Products, Mahmoud A. Sharara
Transformation Of Swine Manure And Algal Consortia To Value-Added Products, Mahmoud A. Sharara
Graduate Theses and Dissertations
The swine production sector is projected to grow globally. In the past, this growth manifested itself in increased herd sizes and geographically concentrated production. Although economically sound, these trends had negative consequences on surrounding ecosystems. Over-application of manure resulted in water quality degradation, while long-term storage of manure slurries was found to promote release of potent GHG emissions. There is a need for innovative approaches for swine manure management that are compatible with current scales of production, and increasingly strict environmental regulations.
This study aims to investigate the potential for incorporating gasification as part of a novel swine manure management …
A Pump Monitoring Approach To Irrigation Pumping Plant Performance Testing, William Merritt Mcdougall
A Pump Monitoring Approach To Irrigation Pumping Plant Performance Testing, William Merritt Mcdougall
Graduate Theses and Dissertations
Traditionally, irrigation pumping plants have been tested using an instantaneous appraoch, which tests performance parameters over a very short time interval. Using this method, the tester measures the necessary work and energy use parameters to calculate the desired pumping plant performance values. The primary limitation of this approach is its inability to determine the season long efficiency of an irrigation pumping plant.
A new approach to evaluating irrigation pumping plant performance is the use of pump monitoring systems which use high frequency, real-time data collection and telemetry to relay information directly from the pump to the user. This method of …
Investigation Of Phanerochaete Chrysosporium And Clostridium Thermocellum For Improved Saccharification Of Lignocellulose Under Nonsterile Conditions, William E. Simon
Investigation Of Phanerochaete Chrysosporium And Clostridium Thermocellum For Improved Saccharification Of Lignocellulose Under Nonsterile Conditions, William E. Simon
Theses and Dissertations--Biosystems and Agricultural Engineering
Current research efforts are directed at developing competitive processes that can utilize lignocellulose as a feedstock for biorefineries. The purpose of this study was to investigate methods of processing lignocellulosic material so that its monosacharides can be more easily accessed for fermentation, the lack of which is hindering the economics and widescale adoption of lignocellulosic biorefining. The monosaccharides are of interest because they can be used by Clostridium beijerinckii downstream of P. chrysosporium and C. thermocellum in a sequential bioprocess to produce butanol. Butanol is an attractive biofuel because it can be utilized without modifying current transportation infrastructure. Butanol is …
