Functional Porous Materials: Applications For Environmental Sustainability, Briana Amaris Aguila
Functional Porous Materials: Applications For Environmental Sustainability, Briana Amaris Aguila
USF Tampa Graduate Theses and Dissertations
Resource depletion, clean water shortages, and global climate change have led to environmental sustainability being of primary concern for both governmental and industrial practices. Current methods to address these challenges typically come as a double-edged sword, fixing one problem while contributing to another. As introduced in chapter one of this dissertation, adsorbent materials are seen as a promising alternative remediation system due to their low energy consumption and minimal chemical waste production. However, many traditional adsorbents, such as activated carbon, metal oxides, and resins, are hindered in practice. This is because they lack the structural tunability to have long-term effectiveness …
An Assessment Of The Influence Of Local Conditions On The Economic And Environmental Sustainability Of Drain Water Heat Recovery Systems, Anusha Ravichandran
An Assessment Of The Influence Of Local Conditions On The Economic And Environmental Sustainability Of Drain Water Heat Recovery Systems, Anusha Ravichandran
USF Tampa Graduate Theses and Dissertations
Increasing resource demand and decreasing supplies necessitate a paradigm shift in wastewater management from treatment to resource recovery. As the economic and environmental performance of wastewater-based resource recovery systems is location-specific (e.g., terrain slope influences hydro-energy recovery), a holistic view of their sustainability requires a comprehensive analysis on the effect of the local conditions on these systems. Although the internal factors affecting such systems (e.g., water quality and end use) are well studied, there is limited literature on the effect of external factors such as topography, climate and population density. This study evaluated the role of climate and population density …
Effects Of Solids Retention Time And Feeding Frequency On Performance And Pathogen Fate In Semi-Continuous Mesophilic Anaerobic Digesters, Nathan Daniel Manser
Effects Of Solids Retention Time And Feeding Frequency On Performance And Pathogen Fate In Semi-Continuous Mesophilic Anaerobic Digesters, Nathan Daniel Manser
USF Tampa Graduate Theses and Dissertations
Anaerobic digestion is a biochemical process in which organic carbon is biodegraded in an oxygen free environment through a microbial consortium. Engineered biological systems used for resource recovery often utilize anaerobic digestion to treat anthropogenic organic wastes by reclaiming the carbon as energy (methane gas) and a soil amendment (biosolids). Small-scale, or household, semi-continuous anaerobic digesters have been used in developed and developing countries for many decades to produce biogas from human and livestock waste, which is used for heating, lighting, and cooking. This application has been shown to improve the quality of life of the user. Although there is …
Inactivation Of Ascaris In Double-Vault Urine-Diverting Composting Latrines In Panama: Methods And Environmental Health Engineering Field Applications, Daragh A. Gibson
Inactivation Of Ascaris In Double-Vault Urine-Diverting Composting Latrines In Panama: Methods And Environmental Health Engineering Field Applications, Daragh A. Gibson
USF Tampa Graduate Theses and Dissertations
The United Nations Millennium Development Goals have prioritized improving access to sanitation, but unfortunately about a third of the global population is still without an improved sanitation source and one billion still practice open defecation. Lack of access to adequate and safe sanitation means the proliferation of dangerous pathogens in the environment, especially soil-transmitted helminths (STHs). In the Bocas del Toro Province of Panama (and similar locations in the world), composting latrines have been built in many of the indigenous communities in the area. They are a form of dry or ecological sanitation and are designed to produce an end …
