Abstract[English]
The invention provides a methodology for treating perfluoroalkyl and polyfluoroalkyl substances, collectively referred to as PFAS, in soils, groundwater, surface water and within other materials. PFAS exhibit a broad range of chemical properties which necessitates the application of a versatile treatment technology. The invention utilises a modified inorgano-organoclay or modified inorgano-organoclays for the treatment of PFAS which provide(s) this essential capability and flexibility. The composition of the modified inorgano-organoclay / modified inorgano-organoclays can be varied accordingly enabling the clays to exhibit varying degrees of hydrophobicity / hydrophilicity. PFAS are sorbed into the modified inorganoclay / modified inorgano- organoclays and chemically immobilised. The clays can be used in combination with cementitious materials to provide an advanced stabilisation process for the treatment of PFAS contamination in soils / other materials or used in isolation for groundwater / surface water treatment. The objective is to reduce the environmental impact of PFAS pollutants.[French]
L'invention concerne une méthodologie de traitement de substances perfluoroalkylées et polyfluoroalkylées, désignées collectivement PFAS, dans les sols, les eaux souterraines, l'eau de surface et dans d'autres matériaux. Les PFAS présentent une large gamme de propriétés chimiques qui nécessite l'application d'une technologie de traitement polyvalente. L'invention utilise une argile organique-inorganique modifiée ou des argiles organiques-inorganiques modifiées pour le traitement des PFAS, lesquelles fournissent cette capacité et cette flexibilité essentielles. La composition de l'argile organique-inorganique/argiles organiques-inorganiques modifiées peut être modifiée en conséquence, ce qui permet aux argiles de présenter des degrés variables de caractère hydrophobe/caractère hydrophile. Les PFAS sont sorbées dans l'argile organique-inorganique/argiles organiques-inorganiques modifiées et immobilisées chimiquement. Les argiles peuvent être utilisées en combinaison avec des matériaux cimentaires pour fournir un processus de stabilisation avancé pour le traitement de la contamination par les PFAS dans les sols/autres matériaux ou utilisées isolément pour le traitement des eaux souterraines/eau de surface. L'objectif est de réduire l'impact environnemental des polluants PFAS.
