Analytical Methods of Testing Solid Waste and Leachate to Determine Landfill Stability and Landfill Biodegradation Enhancement
(Virginia Tech, 2009-09-10)
This was a study undertaken to investigate municipal solid waste (MSW) landfill stability parameters and landfill leachate properties to determine how solid waste and leachate characteristics can be used to describe ...
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 ...
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 ...
High-Intensity Shear as a Wet Sludge Disintegration Technology and a Mechanism for Floc Structure Analysis
(Virginia Tech, 2001-05-29)
By shearing activated sludge using a high shear rotor stator device, bioavailable proteinaceous material can be produced. Operation at elevated temperatures, serves to increase the amount of material that is rendered ...
Investigating the Biostimulating Effects of ESO Addition to a TCE Contaminated Site
(Virginia Tech, 2004-11-17)
Investigating the Biostimulating Effects of ESO Addition to a TCE Contaminated Site Kelli M. Mattson Abstract Remediation of chlorinated ethene contaminated sites presents a problem for the environmental industry. Many ...
EFFECT OF FEED RATE AND SOLID RETENTION TIME (SRT) ON EFFLUENT QUALITY AND SLUDGE CHARACTERISTICS IN ACTIVATED SLUDGE SYSTEMS USING SEQUENCING BATCH REACTORS
(Virginia Tech, 2010-11-30)
A critical element to the successful operation of activated sludge systems is efficient solid liquid separation achieved by bioflocculation. Bioflocculation refers to the process of microbial aggregation to form activated ...
Changes in Septic Tank Effluent Due to Water Softener Use
(Virginia Tech, 2012-09-28)
The compatibility of home water softeners and septic tanks is of concern for the on-site wastewater treatment community. Research has shown that high sodium levels in activated sludge plants can lead to deflocculation and ...
Evaluation of Anaerobic Biodegradation of Organic Carbon Extracted from Aquifer Sediment
(Virginia Tech, 2006-09-06)
In conjunction with ongoing studies to develop a method for quantifying potentially biodegradable organic carbon (Rectanus et al 2005), this research was conducted to evaluate the extent to which organic carbon extracted ...
Groundwater effects of land applied alum residuals
(Virginia Tech, 1991-04-05)
<p>Soil columns of predominantly Peawick and Slagle soils had various amounts of alum residuals, lime and plant nutrients incorporated into the topsoil. A weekly dose of rainwater was applied to each column over a six month ...
