Evaluation of Stability Parameters for Landfills
(Virginia Tech, 2002-08-02)
There are more than three thousand landfills in the United States, in which approximately 55% (1998, U. S. EPA 1999) of the MSW generated in the US is buried. The majority of the landfills are conventional, but in the ...
A Scrolling Geotextile Fabric Filter Device for Primary Clarification
(Virginia Tech, 2002-09-17)
This study investigated the feasibility of using a portable geotextile fabric based filtering device to remove suspended solids from raw sewage. This device was considered to replace a conventional primary clarifier. The ...
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 ...
Cations and activated sludge floc structure
(Virginia Tech, 2002-07-23)
This research was designed to investigate the effect of cations on activated sludge characteristics and also to determine their influence on digestion performance. For this purpose, cations in solution and in floc were ...
Solid Waste Biodegradation Enhancements and the Evaluation of Analytical Methods Used to Predict Waste Stability
(Virginia Tech, 2002-05-02)
Conventional landfills are built to dispose of the increasing amount of municipal solid waste (MSW) generated each year. A relatively new type of landfill, called a bioreactor landfill, is designed to optimize the ...
Solid Waste Degradation, Compaction and Water Holding Capacity
(Virginia Tech, 2002-10-17)
Bioreactor landfills offer a sustainable way to achieve increased waste degradation along with benefits such as enhanced landfill gas (LFG) recovery, reduction in leachate pollution potential and rapid increase in landfill ...
