Abstract:
Soil vapor extraction (SVE) technology has strong potential value in the decontamination of soils dominated by volatile contaminants. In this paper, in order to evaluate in detail the influence of the main factors on the efficiency of SVE, L9(34) orthogonal tests and response surface analysis were carried out using a self-developed one-dimensional SVE system model. A first-order kinetic reaction model was also employed to analyze the relationship between pollutant concentration and time. The thermal reaction unit of SVE technology with a scale consistent with the soil column of the indoor test

Abstract:
Many metal-contaminated soils originate in old abandoned industrial sites. One of the problems encountered in the reclamation of soils lies in the selection of the decontamination techniques. Few data are available to predict the efficiency of the extraction of metals from the contaminated soils. Moreover, a signifiant part of the contamination is often found as particles. These can be extracted from the soils by means of mineralurgical separation techniques. A trial and error procedure is often used for selecting the technique and the procedure parameters. The purpose of this study is to deve

Abstract:
Hydroxyapatite (HA) microspheres of diameter <70 μm have been synthesized by solgel processing. The starting sols were prepared by ultrasonic mixing of concentrated solutions of calcium acetate (1.7M) with 85% H3PO4, followed by emulsification in dehydrated 2-ethyl-1- hexanol. Drops of emulsion were solidified by extraction of water with this solvent. The final thermal treatment was a 2 h soaking in air at 900°C. Properties such as hydraulic resistance and sedimentation rate, which are important for application in ion-exchangers, were superior for our prepared microspheres in comparison wit

Abstract:
L’extraction sous pression réduite est l’une des techniques de dépollution envisageables lorsqu’il y a contamination d’un sol par des composés organiques volatils (COVs). Cette technique consiste à créer une dépression dans le sol et induire un écoulement contrôlé d’air qui entraînera les contaminants volatils dans la phase gazeuse extraite. Les objectifs de ce travail peuvent se résumer de la façon suivante : - caractérisation de la méthode la plus adaptée à déterminer les deux composantes, horizontale et verticale, de la perméabilité à l’air. - étude de l’évolution de la perméabilité à l’air

Abstract:
L'extraction sous pression réduite est un procédé de traitement des sols pollués par des composés organiques volatils. Son principe repose sur la mise en circulation d'un flux gazeux traversant le sol par l'application d'une dépression de quelques centaines de millibars. Une étude paramétrique menée sur un sol réel artificiellement pollué par du trichloréthylène a montré que le débit du flux gazeux n'a qu'une faible influence sur les rendements d'extraction des polluants à cause de mécanismes de transfert limités cinétiquement. L'humidité du sol a une influence négative sur l'efficacité du tra

A técnica de remediação adotada para o caso consistiu na extração in situ dos vapores do solo e no tratamento dos mesmos por adsorção em filtros de carvão ativado (SVE - soil vapor extraction). Os processos de seleção, projeto, implantação, operação e descomissionamento da tecnologia SVE seguiram as metodologias i

Abstract:
Surface and subsurface releases of organic chemicals have resulted in widespread contamination of groundwaters and soils. Frequently, such chemicals are introduced into the subsurface as nonaqueous-phase liquids (NAPLs), which are only slightly miscible with water. These organic liquids tend to migrate downward through the unsaturated soil zone, displacing the pore gases under the action of gravitational forces. During its migration, a portion of the NAPL will become entrapped in the soil pores due to capillary forces, creating zones of persistent contamination in the soil matrix. Organic liqu
