Evaluating The Effectiveness Of Biochar For Treating Wsu Parking Lot Runoff, Alan-Christian Thomas Jan 2018

Evaluating The Effectiveness Of Biochar For Treating Wsu Parking Lot Runoff, Alan-Christian Thomas

Research Opportunities for Engineering Undergraduates (ROEU) Program 2017-18

Various pollutants including pesticides, herbicides, automotive fluids, and excess nutrients from fertilizers are found in high concentrations in urban runoff. There are many technologies that can be used to control and redirect the water flow such as retention basins, constructed wetlands, and rain gardens; however, these methods are specifically focused on controlling water and not necessarily the nutrients and contaminants in the water. There has recently been an increased interest in the potential for using additional materials (e.g., compost, charcoal) to enhance the pollution treatment ability by either adding them to the soil or by engineering prefilters to remove pollutants …


Evaluating The Effectiveness Of Bioswales In Southeast Michigan, Grace Crowe Jan 2018

Evaluating The Effectiveness Of Bioswales In Southeast Michigan, Grace Crowe

Research Opportunities for Engineering Undergraduates (ROEU) Program 2017-18

Bioswales are modern storm water management structures that utilize biological components in a traditional wale to more effectively filter out contaminants. Because of its modern nature the installation and management practices for bioswales is still developing. Perfecting the practices surrounding bioswales in southeast Michigan environment can aid in the advancement of green infrastructure in the state. Wayne State installed a bioswale in one its parking lots in New Center with the help of the Detroit Biodiversity Network (DBN). We wanted to monitor the progression of this existing bioswale throughout the year, observing the system components effecting overall bioswale performance. The …


Integrated Strategies For Sustainable Wastewater-Based Algal Biofuel Production And Environmental Mitigation In The Us, Javad Roostaei Jan 2018

Integrated Strategies For Sustainable Wastewater-Based Algal Biofuel Production And Environmental Mitigation In The Us, Javad Roostaei

Wayne State University Dissertations

Integration of algae cultivation with wastewater treatment has received increasing interest as a cost-effective strategy for biofuel production. However, there has been no full assessment of algal biofuel production with wastewater on macro-scale by taking into account wastewater resources, land availability, CO2 emission resources, and geographic variation. This research addressed and evaluated the use of wastewater for algae cultivation, in terms of modeling and laboratory experiments. The first goal of this research was to develop a spatially explicit lifecycle model, by integrating life cycle assessment (LCA), and Geographic Information Systems (GIS) analysis, for the evaluation of the environmental and economic …
