Abstract

L'invention concerne un système et un procédé de purification de l'eau par capture des contaminants dans un mélange aqueux. L'invention concerne également un système et un procédé permettant de régénérer le système de capture. L'invention concerne en outre un système et un procédé intégrés de capture et de régénération comprenant un récipient de séparation qui abrite un lit de capture et, éventuellement, une électrode en contact électrique avec le lit, ainsi qu'une source d'énergie servant à appliquer une tension à l'électrode. La tension appliquée renforce la capture du contaminant à partir du liquide aqueux sur le lit de capture et la modulation de la tension appliquée renforce la libération du contaminant sur le lit de capture dans le liquide de lavage aqueux pour régénérer le lit. Le liquide de lavage aqueux peut contenir un contre-ion qui se lie au contaminant en formant une phase de contaminant agrégée qui se sépare du liquide de lavage aqueux.
