Abstract

L'invention a trait au domaine du traitement des eaux souillées d'hydrocarbures (H.C.) et pollutions analogues et dans lesquelles il se produit une séparation en une couche supérieure riche en H.C. et résidus et une couche inférieure constituée par une suspension ou émulsion d'H.C. dans l'eau. Selon le procédé, on traite la couche supérieure par des sels d'ammoniums quaternaires pour séparer le résidu lourd d'une couche surnageante claire, analogue au fuel et réutilisable; puis la couche inferieure par un mélange d'un polyose (par exemple amidon) et d'un coagulant (par exemple alun ordinaire) pour obtenir une eau pratiquement non souillée. Application au traitement des eaux chargées de produits pétroliers et, notamment, des eaux recueillies dans les installations de dégraissage et déparaffinage.
