Remediation of metal-contaminated soil and sludge using biosurfactant technology.
Development of environmentally benign approaches to remediation of metal-contaminated soils and sewage sludges are needed to replace currently used techniques of either landfilling or metal extraction using caustic or toxic agents. We report results from four application technologies that use a metal-chelating biosurfactant, rhamnolipid, for removal of metals or metal-associated toxicity from m...
متن کاملBiosurfactant-facilitated remediation of metal-contaminated soils.
Bioremediation of metal-contaminated wastestreams has been successfully demonstrated. Normally, whole cells or microbial exopolymers are used to concentrate and/or precipitate metals in the wastestream to aid in metal removal. Analogous remediation of metal-contaminated soils is more complex because microbial cells or large exopolymers do not move freely through the soil. The use of microbially...
متن کاملRemediation of saturated soil contaminated with petroleum products using air sparging with thermal enhancement.
Pollutants in the form of non-aqueous phase liquids (NAPLs), such as petroleum products, pose a serious threat to the soil and groundwater. A mathematical model was derived to study the unsteady pollutant concentrations through water saturated contaminated soil under air sparging conditions for different NAPLs and soil properties. The comparison between the numerical model results and the publi...
متن کاملRemediation Of A Clay Contaminated With Petroleum Hydrocarbons Using Soil Reagent Mixing
Soil reagent mixing (SRM) is a remediation technique whereby powder or slurried reagents are delivered and mixed in-situ or ex-situ with contaminated soils or sediments by augers or other types of soil mixers. This paper summarises the work carried out for a laboratory treatability study of SRM on clayey soil samples contaminated with petroleum hydrocarbon compounds from a petrol filling statio...
متن کاملDNA-polyfluorophore Chemosensors for Environmental Remediation: Vapor-phase Identification of Petroleum Products in Contaminated Soil.
Contamination of soil and groundwater by petroleum-based products is an extremely widespread and important environmental problem. Here we have tested a simple optical approach for detecting and identifying such industrial contaminants in soil samples, using a set of fluorescent DNA-based chemosensors in pattern-based sensing. We used a set of diverse industrial volatile chemicals to screen and ...
