Assessment Of The Environmental Sustainability Of A Small Water Production Facility In Madagascar, Jesal Patel
Assessment Of The Environmental Sustainability Of A Small Water Production Facility In Madagascar, Jesal Patel
USF Tampa Graduate Theses and Dissertations
Nearly 2.2 billion people around the globe struggle with access to safely managed drinking water (WHO/UNICEF, 2019), however, there have been certain initiatives taken, particularly by means of small water production facilities for enhancing access to basic drinking water services in rural areas. The water production facility, specifically located in the low- and middle-income countries, usually encounter operational difficulties as a result of limited availability of resources and are required to depend on other resourceful countries for goods and services. Although, with limited research done for assessing the environmental sustainability of water facilities in low- and middle-income countries, numerous data …

Mechanistic Modeling Of Photocatalytic Water Disinfection, Omatoyo Kofi Dalrymple
USF Tampa Graduate Theses and Dissertations
The main goal of this research was to develop a mechanism-based model for photocatalytic disinfection of bacteria in water using suspended catalyst pthesiss in batch reactors. The photocatalytic disinfection process occurs as a semiconductor photocatalyst, most commonly titanium dioxide (TiO2), is irradiated with light of wavelength less than 380 nm to produce hydroxyl radicals and other highly reactive oxidants which can inactivate microorganisms. Photocatalytic disinfection involves a complex interaction of many fundamental mechanisms such as light absorption and scattering by semiconductor pthesiss, electrochemical surface reactions, and heterogeneous colloidal stability. Current models, based largely on chemical reacting systems, do …
