Monitoring And Modeling The Hydrological Performance Of Extensive Green Roof Systems, Joseph Seidl
Monitoring And Modeling The Hydrological Performance Of Extensive Green Roof Systems, Joseph Seidl
Theses and Dissertations
Urban stormwater runoff causes many problems for watersheds located within large metropolitan areas, including such detrimental effects as flooding, erosion, pollution, and the increased risk of combined sewerage overflows. Increased amounts of impervious areas resulting from urban sprawl have also been shown to escalate stormwater flows, which exacerbates water management issues in these metropolitan areas. Water resource engineers have progressively turned toward green infrastructure to solve stormwater problems, and green roof systems represent one type of this green infrastructure. As of current, however, green roof systems are largely underused in as an effective stormwater management tool.
The major factor limiting …
Indicator Bacteria In Beach Environments, Brett Bevers
Indicator Bacteria In Beach Environments, Brett Bevers
Theses and Dissertations
Bacterial presence in the environment has become a growing concern in recent years. The exposure of the public to elevated levels of microbes in the environment has been linked with respiratory and gastrointestinal illnesses. It is important to understand the behavior of bacteria in the environment in order to address public health concerns. This project was intended to improve our understanding of bacteria in the environment that are used as indicators for fecal pollution. Using the standard indicator species E. coli and Enterococci data was collected at Bradford Beach in Milwaukee Wisconsin throughout the summer months of 2013 and 2014. …
Hydrodynamic Modeling Of The Green Bay Of Lake Michigan Using The Environmental Fluid Dynamics Code, Paula Estefania Cedillo
Hydrodynamic Modeling Of The Green Bay Of Lake Michigan Using The Environmental Fluid Dynamics Code, Paula Estefania Cedillo
Theses and Dissertations
In this project we created a hydrodynamic model of the Lower Green Bay of Lake Michigan in Wisconsin, United States using the Visual Environmental Fluid Dynamics Code (EFDC). The model includes four tributary rivers to Lower Green Bay as well as the open boundary flow conditions at Chambers Island. This case study is used to: 1) compare the results obtained with a previous study of Lower Green Bay to validate the creation of the model 2) examine the hydrodynamics of the bay, and 3) create a framework for future studies at Lower Green Bay. The Geographic Information used to build …
Sustainable Decolorization Of Reactive And Acid Dye Wastewater Using Photo-Fenton Oxidation Both With And Without Biodegradation: Laboratory And Field Studies, Marissa R. Jablonski
Sustainable Decolorization Of Reactive And Acid Dye Wastewater Using Photo-Fenton Oxidation Both With And Without Biodegradation: Laboratory And Field Studies, Marissa R. Jablonski
Theses and Dissertations
Photo-Fenton oxidation is an advanced oxidation process (AOP) used to degrade low-concentration textile dye wastewater using expensive chemicals. The technique has shown promise in laboratory-scale projects, but has not been scaled up sustainably to function for industry. Aerobic biodegradation is a common biological treatment method used in large-scale textile industrial applications that generates large amounts of hazardous biological waste. This waste is often left open to the elements and subsequently leaches into natural waterways or onto land. This is the first study of its kind to combine the two to treat cottage-scale industry-grade textile wastewater with a dye concentration of …
Applications Of Microbial Desalination And Photocatalytic Disinfection For The Removal Of Contaminants In Drinking Water, Kristen Shirlee-Ann Brastad
Applications Of Microbial Desalination And Photocatalytic Disinfection For The Removal Of Contaminants In Drinking Water, Kristen Shirlee-Ann Brastad
Theses and Dissertations
Trends in drinking water treatment in recent years have been moving toward the use of membrane separation in order to reduce contaminants in water. There are many forms of membrane separation technology such as ultrafiltration, nanofiltration, microfiltration, reverse osmosis, and extruded ion exchange membranes. These membranes have many different applications and may be used to remove many materials from water such as salts, viruses and bacteria, selectively remove cations or anions, or remove organics.
Microbial desalination cells (MDCs) are an emerging concept which use bioelectric potential produced from organics via microbial metabolism to accomplish desalination. MDCs consist of three compartments, …
