Anaerobic Digestion: Factors Effecting Odor Generation
(Virginia Tech, 2005-07-19)
Land application of anaerobically stabilized biosolids is a beneficial method of handling the solid residuals from a wastewater treatment plant. One of the main issues that restrict land application of biosolids is nuisance ...
Phytoremediation Mechanisms of a Creosote-Contaminated Site
(Virginia Tech, 2001-05-17)
In 1990, creosote contamination was discovered at the location of a railroad tie treatment facility active in the 1950s until 1973. In 1997, a phytoremediation field study was implemented with the planting of 1,026 hybrid ...
Effects of the Desorption and Dissolution of Polycyclic Aromatic Hydrocarbons on Phytoremediation at a Creosote-Contaminated Site
(Virginia Tech, 2002-10-14)
Creosote, containing many high molecular weight hydrophobic polycyclic aromatic hydrocarbons (PAH's), is present in the subsurface environment at the Oneida Tie-Yard in Oneida, Tennessee. Phytoremediation using hybrid ...
The Effect of Cations on Volatile Solids Destruction, Odors, and Dewatering in anaerobic digestion
(Virginia Tech, 2008-06-24)
The primary purpose of this study is to understand the effects of wastewater sludge feed cations on volatile solids destruction, odor control, and dewaterability. The role of influent feed cations and addition of chemical ...
Distribution of Colloidal Material in Activated Sludge as Influenced by Cations
(Virginia Tech, 2004-06-07)
Activated sludge influent and effluent from five municipal wastewater treatment plants were analyzed to further elucidate the roles of aluminum, iron, and the monovalent to divalent cation ratio (M/D) on the influent and ...
