AN INVESTIGATION OF SUSTAINABLE FLUORIDE WATER TREATMENT TECHNOLOGIES WITH A FOCUS ON ETHIOPIA
Brunson, Laura R. (2014)Human consumption of unsafe drinking water from an unimproved source is a global issue affecting approximately 748 million people worldwide. While this number has been decreasing in recent years, an additional 1.2 billion ... -
Kinetics and Solvent Effects on Supported Metal Catalysts for Biomass Conversion
Zhao, Zheng (2018)Energy conversion using renewable biomass has significant environmental impact. To acquire high value products using preliminary processed biomass, considerable amount of upgrading reactions has been conducted in liquid-phase ... -
Low-Cost Chemically Activated Cow Bone for Fluoride Removal from Drinking Water: Batch, Field-Scale Column and Business Model Studies
Yami, Teshome Lemma (2017-05-13)Excess fluoride concentrations in drinking water negatively impact the health of communities living in fluoride affected regions of the world by causing dental and skeletal fluorosis and other severe socio-economic problems. ... -
Making Satellite Sensors Better for Hydroclimatic Applications: Evaluation of NASA SMAP Soil Moisture Using Oklahoma’s Environmental Monitoring Network—MESONET
Xu, Chen (2017-12-15)Soil moisture, quantified as the ratio of liquid water to soil in volume or weight, is the measurement of the water that is held in the space between soil particles. Understanding the components of soil, particularly its ... -
Mapping and Analyzing Urban Growth: A Study to Identify Drivers of Urban Growth in West Africa
Adhikari, Pradeep (2016-05)Urban area expansion is one of the most powerful anthropogenic forces changing the earth‘s surface. Such changes are happening at much faster rates in African and Asian cities. Several interconnected but distinct processes ... -
Modeling and Evaluation of Constituents of Emerging Concern Through Wastewater Treatment Processes
Laubacher, Jason (2016-05-13)Constituents of emerging concern (CECs) have accumulated in drinking water source supply over the past decades. Although there are currently no established treatment standards, CECs should be of concern to the public and ... -
Novel, low-cost aluminum (hydr)oxide based materials for fluoride-impacted drinking-water: Batch and column studies
Du, Junyi (2016-05)Simple aluminum (hydr)oxides and layered double hydroxides were synthesized using common chemicals and equipment by varying synthesis temperature, concentrations of extra sulfate and citrate, and metal oxide amendments. ... -
Performance and environmental impact assessment of agricultural waste-based sorbents for phosphorus recovery and reuse
Ding, Yifan (2023-05)Phosphorus is an essential resource, yet global phosphorous reserves are limited, and increasing quantity of high-grade ore is being mined and turned into fertilizers to meet the increasing demand of food. However, since ... -
Phosphorus, Iron and Trace Metal Interactions at the Sediment Layer-Water Column Interface: The Potential Role of Recovered Mine Drainage Residuals
Tang, Zepei (2020-05)Nutrient enrichment, eutrophication and harmful algal blooms are global environmental concerns. The study site, Grand Lake o’ the Cherokees (GLOC) located in northeast Oklahoma, experiences eutrophication due to excess ... -
Quantifying Solar-Powered Removal of Aqueous and Gaseous Sulfide in a Mine Water Passive Treatment System
Wall, Taylor (2018-12-14)Passive treatment systems can improve water quality for mine water discharges. However, some process units, like vertical flow bioreactors (VFBRs), may produce excess sulfide, which can be a source of nuisance odors and ... -
SORPTION AND RELEASE OF NICKEL AND ZINC USING A MIXED ALGAE COMMUNITY COLLECTED FROM A MINE DRAINAGE PASSIVE TREATMENT SYSTEM
Fielding, Ellen (2017-05)Mine water from upwellings in Commerce Oklahoma is treated by the Mayer Ranch Passive Treatment System (MRPTS) to remove contaminants. The last treatment section of MRPTS is referred to as the polishing pond (also known ... -
SURFACTANTS DERIVED FROM 2-HYDROXY-4-(METHYLTHIO)BUTYRIC ACID: PHASE BEHAVIOR, INTERFACIAL ACTIVITY, MICROEMULSIONS AND MORE
Yu, Guangzhe (2013-12)Surfactants derived from 2-hydroxy-4-(methylthio) butyric acid were investigated. Anionic surfactants derived from this molecule have excellent water solubility, hardness tolerance and surface activity. Nonionic surfactants ... -
Synthesis and Characterization of Porous Hydroxyapatite Ceramics for Batch and Column Treatment of Fluoride-Impacted Ground Water
Nijhawan, Anisha (2019-05-10)Nearly 200 million people worldwide are exposed to drinking water with elevated levels of naturally occurring fluoride. The World Health Organization recommends a maximum fluoride concentration of 1.5 mg/L in drinking water ... -
