Sorption and biodegradation of phenanthrene in soils
(Virginia Tech, 1994-05-05)
<p>Soils and groundwaters face an influx of contaminants, many of which are known to be hazardous to the public's health. Several remediation technologies have been developed to clean-up contaminated soils, but additional ...
Removal of trace elements from coal using a multiple-property processing circuit
(Virginia Tech, 1994-07-15)
<p>The U.S. Environmental Protection Agency is conducting a three-year study of toxic air emissions specific to coal fired utilities to assess the potential health risks of trace elements released during coal combustion. ...
The effects of ozone treatment on chemical parameters of a recirculating aquaculture system producing hybrid striped bass
(Virginia Tech, 1994-08-05)
The hypothesis tested in this study is that the application of ozone to reuse aquaculture water provides more favorable conditions for hybrid striped bass at production levels. Evaluation of water quality in fish culture ...
Sorption of pentachlorophenol to humic acids and subsequent effects on biodegradation and solvent extraction
(Virginia Tech, 1992-06-05)
Laboratory evaluation of conditioning requirements for sludge dewatering using belt filter press
(Virginia Tech, 1990-12-06)
Variations in the biodegradation potential of toluene with increasing depth in an unsaturated subsurface environment
(Virginia Tech, 1990-03-15)
<p>A microcosm study was performed to investigate the biodegradation potential of BTX compounds in unsaturated soils under aerobic and anaerobic conditions. Toluene was used as a model compound at concentrations of 100 to ...
Iron oxidation coupled with biodegradation of organic contaminants in a simulated ground water system
(Virginia Tech, 1991-05-22)
<p>Aerobic degradation of hydrocarbon contaminants in anaerobic ground water would be enhanced by oxygenating the water. However, when a contaminated ground water contains high concentrations of reduced iron, competition ...
Analysis and Prevention of Usable Fiber Loss from a Fine Paper Mill
(Virginia Tech, 1998-09-17)
Reducing losses of usable waste fiber from paper mills conserves valuable resources and has the capacity to produce considerable economic returns to the manufacturer. The purpose of this research effort was to evaluate ...
Study of Hydrocarbon Waste Biodegradation and the Role of Biosurfactants in the Process
(Virginia Tech, 1998-08-21)
Two types of oily waste sludges generated by a railroad maintenance facility were studied to reduce the volume of hydrocarbon waste. The specific goals of this laboratory study were to evaluate rate and extent of ...
The biodegradation potential of methanol, benzene, and m-xylene in a saturated subsurface environment
(Virginia Tech, 1993-03-15)
<p>The increased use of alcohols as gasoline additives, and possible substitutes, has prompted the investigation of the fate of gasoline/alcohol mixtures in the environment. In situ bioremediation is one technique that can ...
