Abstract

L'invention concerne des compositions, des systèmes et des procédés pour éliminer les substances perfluoroalkylées et polyfluoroalkylées de l'eau. Les procédés de l'invention permettent d'éliminer les substances perfluoroalkylées et polyfluoroalkylées en mélangeant de l'eau contaminée avec une enzyme conjointement avec un catalyseur métallique non toxique, en filtrant le mélange, et en récupérant le catalyseur métallique à partir du flux de rétentat. L'invention concerne des procédés d'utilisation du catalyseur pour améliorer les performances de réaction tout en réduisant à un minimum la masse totale de catalyseur nécessaire au traitement. Contrairement aux procédés concurrents, le procédé décrit ici ne produit que peu ou pas de résidus.
