Title
(EN) WATER-IN-OIL-IN WATER EMULSIONS OF HYDROXAMATED POLYMERS AND METHODS FOR USING THE SAME
(FR) EMULSIONS EAU DANS L'HUILE DANS L'EAU DE POLYMERES HYDROXAMATES ET LEURS METHODES D'UTILISATION
Abstract
(EN)
A method and composition for flocculation and separation of suspended solids from an industrial process stream containing suspended solids is provided. The method includes the steps of adding to the stream a water-in-oil-in-water emulsion polymer in an amount effective to flocculate the suspended solids and separating the flocculated solids therefrom. The composition is a water-in-oil-in-water emulsion of a water-soluble polymer in which the continuous phase is an aqueous solution of a water-soluble salt.

L'invention concerne une méthode et une composition pour la floculation et pour la séparation de solides en suspension provenant d'un flux de procédé industriel contenant des solides en suspension. Cette méthode comprend les étapes consistant à: ajouter à ce flux un polymère d'émulsion eau dans l'huile dans l'eau, dans une quantité efficace pour faire floculer les solides en suspension et pour séparer les solides floculés de ce flux. La composition est une émulsion eau dans l'huile dans l'eau d'un polymère soluble dans l'eau dans lequel la phase continue est une solution aqueuse d'un sel soluble dans l'eau.
