CA 2199497

The present invention relates to water treatment, in particular to a process for the removal of dissolved organic carbon from water. The process includes the following steps, adding an ion-exchange resin to water containing a contaminant such as dissolved organic carbon, dispersing the resin in the contaminated water to enable adsorption of the dissolved organic carbon onto the resin, and separating the resin loaded with contaminant from the water. In a preferred embodiment the process employs a magnetic ion-exchange resin.

L'invention concerne un traitement des eaux particulièrement destiné à éliminer le carbone organique qui y est dissous. Ce procédé consiste à ajouter une résine d'échange ionique aux eaux contenant un polluant tel que du carbone organique dissous, à disperser cette résine dans les eaux polluées pour permettre l'adsorption du carbone organique dissous sur la résine, et à séparer ces eaux de la résine chargée du polluant. Dans une variante préférée, ce procédé implique l'utilisation d'une résine magnétique d'échange ionique.
