Biochar Amended Biological Systems For Enhanced Landfill Leachate And Lignocellulosic Banana Waste Treatment, Xia Yang
USF Tampa Graduate Theses and Dissertations
Biochar is an inexpensive and environmentally friendly carbonaceous pyrolysis byproduct with a high surface area, pore volume, and adsorption capacities for inorganic and organic compounds. The goal of this dissertation is to evaluate the feasibility of biochar application in biological treatment systems for enhanced waste management. Three major objectives guided this research to provide a compressive understanding of biochar enhancement effects on biological treatment systems for contaminant removal, energy recovery, and environmental impacts as well as essential factors influencing biochar production and properties.
In Objective 1 a low-cost hybrid Constructed Wetland (CW) system modified with biochar/zeolite was developed for enhanced …

Modified Biosand Filtration Using Aluminum Hydroxide Filter Media To Enhance Fluoride Removal, Joshelyn Guimaray
USF Tampa Graduate Theses and Dissertations
There are over 20 countries whose citizens consume groundwater containing high levels of fluoride, including Nigeria, Mexico, India, China, and Ghana, which all have major health crises when it comes to the safety of their drinking water. Minerals like fluorite contain fluoride which is often found in groundwater aquifers. The minerals release fluoride into the groundwater. Per the World Health Organization (WHO) standard, the maximum contaminant limit for fluoride consumption should be less than 1.5 mg/L. Chronic exposure of elevated levels of fluoride can cause people to suffer debilitating health effects, such as dental and skeletal fluorosis. Dental fluorosis causes …
