Application of a Thermally Modified Agrowaste Material for an Economically Viable Removal of Cr(VI) from Aqueous Solutions
(American Society of Civil Engineers, 2013)Removal of Cr(VI) from aqueous solutions has been investigated by adsorption on a low-cost adsorbent, calcined rice husk (CRH). Rice husk is an agrowaste material. It was thermally treated in a muffle furnace at 650°C for ... -
Detection of Aluminum Waste Reactions and Waste Fires
(American Society of Civil Engineers, 2013)Aluminum production wastes (APW) placed in Subtitle D regulated landfills may react exothermically and cause uncontrolled temperature increases, large volumes of explosive and toxic gasses, increases in landfill gas pressure ... -
Removal of Chromium from Electroplating Industry Effluent Using Electrocoagulation
(American Society of Civil Engineers, 2013)Experiments were performed in batch mode of operation using iron electrodes to remove chromium from effluent by electrocoagulation, and the effect of various operating parameters was investigated. The maximum hexavalent ... -
Mitigation of Chromium Contamination by Copper-ZVI Bimetallic Particles
(American Society of Civil Engineers, 2013)Soil and water pollution by chromium is a major environmental concern. Although existence of chromium in the -
Rehabilitation of the Barzava Uranium Mine Tailings
(American Society of Civil Engineers, 2013)Results are presented and discussed concerning the radiometric survey of the Barzava uranium mine tailings (Arad District, Romania), a -
Seismic Imaging of a Leachate-Recirculation Landfill: Spatial Changes in Dynamic Properties of Municipal Solid Waste
(American Society of Civil Engineers, 2013)Leachate-recirculation landfills enhance waste degradation through percolation of leachate inside the waste mass. In situ monitoring of moisture distribution and changes in mechanical properties (stiffness) of municipal ... -
Source Term Evaluation Model for Uranium Tailings Ponds
(American Society of Civil Engineers, 2013)A multicompartmental source term model, which is designed to assess the radionuclide leaching and transport in a saturated or unsaturated porous medium such as a uranium tailings pond (or near-surface radioactive waste ... -
Study on the Correlation between Dissolved Organic Carbon, Specific Oxygen Uptake Rate, and Exchangeable Nitrogen and the Performance of Granular Materials as Support Media for Methanotrophic Biofiltration
(American Society of Civil Engineers, 2014)Anaerobic decomposition of organic materials in landfills is a key source of anthropogenic methane ( -
Hydrated Lime for Metal Immobilization and Explosives Transformation: Field Demonstration
(American Society of Civil Engineers, 2013)This field demonstration investigated the application of alkaline hydrolysis for full-scale in situ remediation and control of munitions constituents, residues of explosives, and metals in hand grenade range soil. ... -
Enhancing Gas Production in Landfill Bioreactors: Flow-Through Column Study on Leachate Augmentation with Enzyme
(American Society of Civil Engineers, 2013)Landfill bioreactors have many advantages relative to conventional dry-tomb sanitary landfills. Leachate augmentation with enzymes (prior to its recirculation) to enhance waste degradation and gas production in landfill ... -
Postclosure Long-Term Settlement for MSW Landfills
(American Society of Civil Engineers, 2013)A mathematical model is developed to estimate the settlement attributable to biodegradation for municipal solid waste (MSW) landfills incorporating the effects of pH, temperature, and moisture content. The post closure ... -
Operation of a Landfill Bioreactor in a Cold Climate: Early Results and Lessons Learned
(American Society of Civil Engineers, 2013)This manuscript presents a detailed discussion of the challenges faced and lessons learned during the initial phase of operation of the Calgary Biocell. The Calgary Biocell is a full-scale pilot project that has been ... -
DNA-Based Methods Reveal Complex Kinetics of MSW Leachate Anaerobic Digestion
(American Society of Civil Engineers, 2013)Anaerobic biodegradation is one of the most important natural attenuation mechanisms for contaminants in the vadose zone. It is responsible for preventing many organic pollutants from reaching the aquifer. It has usually ... -
Large-Scale Bioreactor Pilots for Monitoring the Long-Term Hydromechanics of MSW
(American Society of Civil Engineers, 2013)Municipal solid waste (MSW) in landfill bioreactors is subjected to mechanical, biological, and hydrological processes. To understand these processes, four large-scale bioreactor pilots were specifically designed to simulate ... -
Rice Germination as a Bioassay to Test the Phytotoxicity of MSWI Bottom Ash Recycling Wastewater
