Aerobic Biodegradation of MTBE in Uncontaminated and Gasoline-Contaminated Aquifer Sediments
(Virginia Tech, 1999-07-12)
In this study, the biodegradation potential of MTBE in uncontaminated and previously contaminated aquifer sediments under aerobic conditions was investigated. Laboratory microcosms were constructed using aquifer samples ...
Effect of sugar waste, surfactant waste and paint waste on the degradation of anaerobic bioreactor landfill components
(Virginia Tech, 2007-04-30)
Anaerobic bioreactor landfills are the landfills with an increased moisture content inorder to achieve a better biodegradation. Many Bioreactor landfills accept outside liquid wastes to achieve a higher moisture content . ...
Effects of Grasses on the Remediation of Creosote-Contaminated Surface Soil
(Virginia Tech, 1999-05-05)
A grass phytoremediation field study was initiated in July 1997 at the site of a former railroad tie facility that used creosote for tie preservation. The site is contaminated with polycyclic aromatic hydrocarbons (PAHs). ...
Water chemistry characterization and component performance of a recirculating aquaculture system producing hybrid striped bass
(Virginia Tech, 1992-06-05)
<p>Eight identical and independent pilot scale recirculating aquaculture production systems were populated with fingerling hybrid striped bass <i>(Morone chrysops</i> female x <i>Morone saxatilis male</i>). Three population ...
Identification and generation pattern of odor-causing compounds in dewatered biosolids during long-term storage and effect of digestion and dewatering techniques on odors
(Virginia Tech, 2011-08-11)
The main objective of this research was to identify the compounds responsible for persistent odors in biosolids during long-term storage using olfactometry measurements and to determine their generation pattern with regard ...
Biopolymer and Cation Release in Aerobic and Anaerobic Digestion and the Consequent Impact on Sludge Dewatering and Conditioning Properties
(Virginia Tech, 1998-08-27)
Sludge dewatering and chemical conditioning requirements were examined from the perspective of biopolymer and cation release from activated sludge flocs. Both aerobic and anaerobic digestion processes were considered ...
The Biological Sludge Reduction by anaerobic/aerobic cycling
(Virginia Tech, 2010-03-29)
An activated sludge system that incorporates a sidestream anaerobic bioreactor, called the Cannibal process, was the focus of this study. A prior study of this process (Novak et al., 2007) found that this system generated ...
