Biosurfactant-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 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 کاملElectrokinetic remediation of oil-contaminated soils.
This investigation was undertaken to determine the factors influencing electrokinetic remediation of soils from petroleum pollutants. The remediation method was applied in two versions: (i) static and (ii) flowing, when a sample was washed with leaching solution. It was found that all the soils studied can be purified using this technique. It was also observed that the mineral and grain-size co...
متن کاملThermal Remediation of Tar-Contaminated Soil and Oil-Contaminated Gravel
Pilot plant studies were carried out to evaluate the feasibility of remediation of coal tarcontaminated soil and oil-contaminated gravel by incineration with environmentally acceptable performance. In addition to adequate decontamination and emission control, effort was devoted to treating the special feedstocks with difficult handling properties by use of conventional combustion and feeding sy...
متن کاملMicrowave thermal remediation of crude oil contaminated soil enhanced by carbon fiber.
Thermal remediation of the soil contaminated with crude oil using microwave heating enhanced by carbon fiber (CF) was explored. The contaminated soil was treated with 2.45 GHz microwave, and CF was added to improve the conversion of microwave energy into thermal energy to heat the soil. During microwave heating, the oil contaminant was removed from the soil matrix and recovered by a condensatio...
