Title
(EN) PROCESS FOR THE TREATMENT OF CONTAMINATED WATER BY MEANS OF ADSORPTION AND MANOFILTRATION
(FR) PROCÉDÉ POUR LE TRAITEMENT D'UNE EAU CONTAMINÉE AU MOYEN D'UNE ADSORPTION ET D'UNE NANOFILTRATION
Abstract
(EN)
A process for the treatment of water contaminated by polar and/or apolar organic compounds, and/or by heavy metal salts, and/or by oil dispersed or in emulsion, comprising sending said contaminated water to a system comprising: at least one adsorption (3) unit including at least one microporous or mesoporous alumino-silicate; at least one nanofiltration unit (7) including at least one hydrophilic nanofiltration membrane; wherein said hydrophilic nanofiltration membrane has a contact angle with water lower than or equal to 45°, preferably ranging from 25° to 40°.
(FR)
L'invention concerne un procédé de traitement de l'eau contaminée par des composés organiques polaires et/ou apolaires, et/ou par des sels de métaux lourds, et/ou par de l'huile dispersée ou en émulsion, consistant à envoyer ladite eau contaminée dans un système comprenant : au moins une unité d'adsorption (3) comprenant au moins un alumino-silicate microporeux ou mésoporeux; au moins une unité de nanofiltration (7) comprenant au moins une membrane de nanofiltration hydrophile; ladite membrane de nanofiltration hydrophile ayant un angle de contact avec l'eau inférieur ou égal à 45°, de préférence se situant dans la plage de 25° à 40°.
