Title (EN) SOIL AND WATER REMEDIATION METHOD AND APPARATUS FOR TREATMENT OF RECALCITRANT HALOGENATED SUBSTANCES
(FR) PROCÉDÉ DE RÉHABILITATION DE SOL ET D’EAU ET APPAREIL POUR LE TRAITEMENT DE SUBSTANCES HALOGÉNÉES ET RÉCALCITRANTES
Abstract:
(EN) Disclosed are methods, apparatuses and systems for the remediation of contaminated soils, groundwater, water, and/or waste using a combination of reagents. The disclosed methods may be used to treat various recalcitrant halogenated substances, such as perfluoroalkyls and polyfluoroalkyls. Particular combinations of reagents that may be used in the disclosed methods include but are not limited to: (1) persulfate, oxygen and ozone; (2) persulfate, salt, oxygen and ozone; (3) persulfate, phosphate, and/or oxygen; (4) persulfate, phosphate, oxygen and ozone; (5) persulfate, phosphate, salt and oxygen (6) persulfate, phosphate, salt, oxygen and ozone; (7) oxygen and salt; and (8) air and salt. The disclosed methods may enhance destruction of organic contaminants in the liquid phase and may also control the rate of aerosol or foam formation relative to the rate of chemical oxidation and/or reduction/transfer.
(FR) La présente invention concerne des procédés, des appareils et des systèmes pour la réhabilitation de sols, eau souterraine, eau et/ou déchets contaminés au moyen d’une combinaison de réactifs. Les procédés de l’invention peuvent être utilisés pour traiter différentes substances halogénées récalcitrantes telles que des perfluoroalkyles et des polyfluoroalkyles. Des combinaisons particulières de réactifs qui peuvent être utilisées dans les procédés de l’invention comprennent, mais ne sont pas limitées à : (1) persulfate, oxygène et ozone ; (2) persulfate, sel, oxygène et ozone ; (3) persulfate, phosphate et/ou oxygène ; (4) persulfate, phosphate, oxygène et ozone ; (5) persulfate, phosphate, sel et oxygène ; (6) persulfate, phosphate, sel, oxygène et ozone ; (7) oxygène et sel ; et (8) air et sel. Les procédés selon l'invention peuvent augmenter la destruction de contaminants organiques dans la phase liquide et peuvent en outre contrôler le taux de formation d’aérosol ou de mousse par rapport au taux d'oxydation et/ou réduction/transfert chimique.
