More Information
Summary:A treatment system and a method for removal of at least one halogenated compound, such as PCBs, found in contaminated systems are provided. The treatment system includes a polymer blanket for receiving at least one non-polar solvent. The halogenated compound permeates into or through a wall of the polymer blanket where it is solubilized with at least one non-polar solvent received by said polymer blanket forming a halogenated solvent mixture. This treatment system and method provides for the in situ removal of halogenated compounds from the contaminated system. In one embodiment, the halogenated solvent mixture is subjected to subsequent processes which destroy and/or degrade the halogenated compound. La présente invention concerne un système de traitement et un procédé permettant d'éliminer au moins un composé halogéné, tel que des PCB, se trouvant dans un système contaminé. Le système de traitement comprend une couche de polymère servant à recevoir au moins un solvant non polaire. Le composé halogéné passe dans ou à travers une paroi de la couche de polymère où il est solubilisé avec au moins un solvant non polaire reçu par ladite couche de polymère, ce qui forme un mélange de solvants halogénés. Le système et le procédé de traitement permettent d'éliminer in situ les composés halogénés se trouvant dans le système contaminé. Dans un mode de réalisation, le mélange de solvants halogénés est soumis à un procédé ultérieur qui détruit et/ou dégrade le composé halogéné.
