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 ...
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 ...
Polycyclic Aromatic Hydrocarbons and Redox Parameters in a Creosote-Contaminated Aquifer
(Virginia Tech, 2001-02-05)
A groundwater monitoring study was conducted as part of a comprehensive program to remediate a former wood-preserving site that was contaminated with creosote. Twenty-five multi-level samplers (MLSs) were installed on-site ...
Laboratory evaluation of conditioning requirements for sludge dewatering using belt filter press
(Virginia Tech, 1990-12-06)
Sorption of pentachlorophenol to humic acids and subsequent effects on biodegradation and solvent extraction
(Virginia Tech, 1992-06-05)
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 ...
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. ...
Effect of Reactor Feeding Pattern on Performance of an Activated Sludge SBR
(Virginia Tech, 2006-09-19)
<p> The possible effects of changes in the feeding pattern on activated sludge properties related to bioflocculation have been analyzed in lab scale sequencing batch reactors (SBR) in order to determine if these changes ...
Assessment of Intrinsic Bioremediation at a PCE Contaminated Site
(Virginia Tech, 2000-08-18)
Groundwater parameter analysis, microcosm experiments, and microcosms modeling were undertaken to assess the potential of Monitored Natural Attenuation as a remediation strategy at Site 12 at the Naval Amphibious Base (NAB) ...
Developing a Mechanistic Understanding and Optimization of the Cannibal Process: Phase II
(Virginia Tech, 2006-08-29)
The Cannibal system, comprised of an activated sludge process integrated with a side stream anaerobic bioreactor, is capable of reducing excess sludge up to 60% compared to the conventional activated sludge process. The ...
