Identification Of Phosphorous Loading Point Source Facilities To 303(D) Listed Nutrient Impaired Waters Through Watershed Delineation Using Arcgis For Life Cycle Assessment Applications, John Zimmerman
Chemical Engineering Undergraduate Honors Theses
The work done for this project is part of a larger “life cycle assessment (LCA) of novel electrochemical phosphorus recovery technology at the wastewater treatment plant and U.S. watershed scales” (Morrissey 2019). The goal of that LCA is to determine “environmental impacts of implementing electrochemical struvite recovery at the wastewater treatment plant, U.S watershed, and global scales” (Morrissey 2019). This project’s goal is to identify locations deemed more sensitive to eutrophication impacts. The results will be used as part of the life cycle inventory (LCI) accounting for geographically explicit phosphorus flows. The waters identified as impaired were sourced from the …
Recycling Wastewater For Hydraulic Fracturing By Use Of Nanofiltration Membranes, Haley D. Cleous
Recycling Wastewater For Hydraulic Fracturing By Use Of Nanofiltration Membranes, Haley D. Cleous
Chemical Engineering Undergraduate Honors Theses
Hydraulic fracturing creates large volumes of produced water, contaminated with organics, suspended solids, and dissolved minerals. This water must either be disposed of in injection wells or treated for reuse. One option is to use a combination of ultrafiltration and nanofiltration to treat this water and reuse it in future hydraulic fracturing wells. The object of this study was to test and characterize commercial nanofiltration membranes. The work done for this project will lead to future work in modifying membranes to improve the rejection of desired components.
