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 …
Accumulation Of Lead By Biofilms In Drinking Water Distribution Systems, Kaleb Oren Belcher
Accumulation Of Lead By Biofilms In Drinking Water Distribution Systems, Kaleb Oren Belcher
Graduate Theses and Dissertations
Recent crises, such as the one in Flint, MI, indicate that lead exposure from drinking water is a major health concern in the United States. Over six million lead service lines are still in use in the United States, and a universal protocol to safely remove these lead service lines from drinking water distribution systems has not yet been established. This paper calls to attention the potential hazard that biofilms pose as a source of lead in distribution systems, even after the removal of lead pipes. This study used a simulated water distribution system containing a lead source pipe and …

Mathematical Modeling Of Fluid Spills In Hydraulically Fractured Well Sites, Oluwafemi Michael Taiwo
Graduate Theses and Dissertations
Improved drilling technology and favorable energy prices have contributed to the rapid pace at which the exploitation of unconventional natural gas is taking place across the United States. As a natural gas well is being drilled, reserve pits are constructed to hold the drilling fluids and other materials returned from the drilling process. These reserve pits can fail, and when they do, plant and animal life of the surrounding area may be adversely affected. This project develops a screening tool for a suitable location for a reserve pit. This work will be a critical piece of the Infrastructure Placement Analysis …

Automation Of The Continuous Coagulation Monitor, Dee Mitchell, James J. Oskowis
Technical Reports
The development of automation in the past 50 years has paralleled the accelerating growth of today’s vast technological society. Automatic control systems are indispensable extensions of man's brain that enable him to monitor and regulate his complex environment. The principles of automatic control have a wide range of applications and interests in virtually every scientific field. The need for automatic control systems in vital applications of environmental engineering is both real and urgent. Extensive pollution has resulted in unavoidable water re-use and in the inevitable establishment of stringent effluent standards. Both water and wastewater treatment processes have necessarily become more …
