Engineered Porous Media For Groundwater Contaminant Remediation: Applications Of Nano-Tio2, Sheng Yin
Engineered Porous Media For Groundwater Contaminant Remediation: Applications Of Nano-Tio2, Sheng Yin
Theses and Dissertations
Nonmetallic Arsenic and hydrocarbon BTEX are the most common and harmful contaminants in groundwater. Many oxide, biological and metal based adsorbent materials have been investigated in the laboratory and in the field environment. These materials, especially for nano-TiO2, have been extensively studied in the laboratory due to its high efficiency and remediation outcomes. This research compared two different synthetic nano-TiO2, aggregated dendritic nano-scale anatase TiO2 and the polymorphed rutile nano-TiO2 attached to the surface of SiO2, to study the feasibility of nano-TiO2 in geoenvironmental engineering applications. Characterization of crystal structure, purity, and morphologic, microscopic features of the materials were examed …
Virus Adsorption To Colloids In Water: Interactions Between Bacteriophage Ms2, Kaolinite, And Fiberglass, Ashlee N. Ellis
Virus Adsorption To Colloids In Water: Interactions Between Bacteriophage Ms2, Kaolinite, And Fiberglass, Ashlee N. Ellis
Theses and Dissertations
Virus adsorption to colloidal particles is an important issue in the water quality community, and it is a particularly important issue for conventional wastewater treatment plants that accept biohazardous waste. Colloids impact the transport of viruses in engineered treatment systems, and they also provide protection against oxidants and other destructive mechanisms. This study evaluated the adsorption of bacteriophage MS2 to colloidal suspensions of kaolinite (KAO) and fiberglass (FG). A series of laboratory batch tests were carried out over a range of experimental conditions to determine kinetic rate constants and characterize bond strength, and computational experiments were done to assess both …
