Title (EN) DEVICES AND METHODS FOR THE REMEDIATION OF GROUNDWATER
(FR) DISPOSITIFS ET PROCÉDÉS D'ASSAINISSEMENT D'EAUX SOUTERRAINES
Abstract:
(EN) Provided herein are devices, systems, and methods for removing contaminant ions from water within an aquifer. The devices, systems, methods employ an elecrokinetic driving force to induce the migration of charged species towards electrodes, where they can be concentrated and removed from the aquifer. In this way, the devices, systems, methods described herein can be used to economically remediate groundwater contaminated with charged species.
(FR) L'invention concerne des dispositifs, des systèmes et des procédés pour éliminer des ions contaminants de l'eau à l'intérieur d'un aquifère. Les dispositifs, systèmes et procédés utilisent une force d'entraînement électrocinétique pour induire la migration d'espèces chargées vers des électrodes, où elles peuvent être concentrées et retirées de l'aquifère. De cette manière, les dispositifs, les systèmes et les procédés décrits ici peuvent être utilisés pour assainir économiquement les eaux souterraines contaminées par des espèces chargées.
