Efficient Management Of Nitrogen And Phosphorus At Centralized Water Reclamation Facilities, Helene Kassouf
Efficient Management Of Nitrogen And Phosphorus At Centralized Water Reclamation Facilities, Helene Kassouf
USF Tampa Graduate Theses and Dissertations
A variety of process configurations are employed at municipal water reclamation facilities (WRFs), such as 5-stage Bardenpho, oxidation ditch, modified Ludzack-Ettinger (MLE) process, and sidestream recycle. However, all of these configurations face certain challenges in achieving optimum treatment of nitrogen and phosphorus. In this dissertation, the driving objectives were to: (1) quantitatively assess the fate of nitrogen and phosphorus (mass fluxes) at a treatment facility that employs biological nutrient removal, aerobic digestion, and sidestream recycle, (2) evaluate the performance of a microbial fuel cell (MFC) as a technology to remove nitrogen from sidestreams at a treatment plant that employs that …
Fiber-Based Supercapacitor For Wearable Electronics, Rohit Lallansingh Yadav
Fiber-Based Supercapacitor For Wearable Electronics, Rohit Lallansingh Yadav
USF Tampa Graduate Theses and Dissertations
Supercapacitors are significant devices that are used for energy storage and also have the capability of delivering energy at a faster rate than batteries. The increase in the significance of portable and wearable electronic equipment giving rise to pace in the development of flexible supercapacitor and flexible electrodes in recent years. A fiber-based supercapacitor (FSCs) is one of the most significant devices which have even helped us give pace knowing the properties of supercapacitor. These FSCs are said to have excellent electrochemical properties and flexibility. This did make function it in different forms of individual fibers or integrated textiles which …
Sensible/Latent Hybrid Thermal Energy Storage For The Supercritical Carbon Dioxide Brayton Cycle, Kelly Osterman
Sensible/Latent Hybrid Thermal Energy Storage For The Supercritical Carbon Dioxide Brayton Cycle, Kelly Osterman
USF Tampa Graduate Theses and Dissertations
Mitigating the effects of climate change will require rapid deployment of a carbon-free electricity system that includes all available forms of zero-carbon energy. Both renewables and nuclear show great promise, but both come with drawbacks. Power production from wind and solar is limited to times when their respective resources are available, while nuclear is limited in its ability to adjust its output according to the ever-varying demand for electricity. Additionally, the systems must be affordable. One way to reduce the cost of thermal power plants (concentrated solar power and nuclear) is to use new power cycles, such as the supercritical …
Fabrication And Characterization Methods Of Self-Cleaning Coatings For Solar Panels Application, Mohammed Khaleel M Alhussain
Fabrication And Characterization Methods Of Self-Cleaning Coatings For Solar Panels Application, Mohammed Khaleel M Alhussain
USF Tampa Graduate Theses and Dissertations
Transparent self-cleaning coatings with superhydrophobic and superhydrophilic behavior are of great interest in a wide range of industrial applications such as automotive, solar panels, windows, and optical devices. Each has its uses, properties, and characteristics. For the use of these coatings on solar panels, certain features are important in maintaining the efficiency of the panels in different weather conditions and reducing the operation and maintenance cost, such as self-cleaning, high transparency, antifouling, anti-fogging, and anti-icing. Herein, we have investigated the fabrication of self-cleaning coatings using two simple methods and ways to improve their characteristics. In the first method, a hydrophobic …
