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 …
Modeling Water Quality For Switchgrass Crop Production: Implications For Bioenergy Sustainability In East Tennessee, Zachariah Tzvi Seiden
Modeling Water Quality For Switchgrass Crop Production: Implications For Bioenergy Sustainability In East Tennessee, Zachariah Tzvi Seiden
Masters Theses
With passing of the US Energy Independence and Security Act (EISA) of 2007, there has been considerable research conducted on the sustainability of bioenergy crop production in the United States; switchgrass has shown particular potential for bioenergy production in East Tennessee. Many studies evaluating the environmental impact switchgrass has on runoff and water quality use the Soil and Water Assessment Tool (SWAT) for watershed modeling. Because SWAT is a lumped watershed model, it evaluates the result of hydrological processes for each hydrologic response unit (HRU), without accounting for the physical interactions between these HRUs. The Water Erosion Prediction Project (WEPP) …
Evaluation Of Multiple Disinfection Methods To Mitigate Contaminated Irrigation Water, Tianju Chang
Evaluation Of Multiple Disinfection Methods To Mitigate Contaminated Irrigation Water, Tianju Chang
Masters Theses
Outbreak of foodborne pathogens associated with fresh produce is a concern to produce growers. Irrigation water is one of the pathways of produce contamination. The U.S. Food and Drug Administration (FDA) proposed a set of guidelines for irrigation water that includes a maximum generic E.coli count lower than 126MPN/100mL. Irrigation is typically a continuous-flow process: water is withdrawn from a source and applied to a crop. In order to disinfect irrigation water, a process must be developed to provide treatment while the water is in the hydraulic network. However, studies related to the continuous flow irrigation water disinfection (CFIWD) system …
