Abstract
La présente invention se rapporte à l'élimination des composés terpéniques dans les eaux résiduaires provenant du traitement des bois résineux. Elle propose un procédé dans lequel on ajoute, aux eaux à traiter, un agent floculant du type acide de Lewis, on laisse relarguer les flocs, puis on sépare le liquide épuré des flocs. Pour obtenir un faible coût de traitement, on n utilise que peu d'agent floculant, à condition d'ajouter une quantité déterminée d'acide sulfurique. Elle propose également un dispositif pour mettre en oeuvre le procédé. L'invention trouve une application dans l'épuration des eaux résiduaires des industries traitant des bois résineux, en particulier les eaux de papeteries et elle permet de récupérer des composés terpéniques.
