Title
(EN) COMBINATION OF FLOCCULANT WITH SURFACTANT FOR WASTEWATER TREATMENT
(FR) COMBINAISON DE FLOCULANT ET DE TENSIOACTIF POUR TRAITER DES EAUX USÉES
Abstract
(EN)
A method and formulations for treatment of wastewater by combination of a flocculant and surfactant are described herein. The co-addition of the flocculant with an anionic, cationic or non-ionic surfactant produces improved separation of contaminants from wastewater to yield pure or highly pure water. An optimal ratio between the flocculant and the surfactant applied allows for reduction of the amount of flocculant required to treat the wastewater.
(FR)
L'invention concerne un procédé et des préparations qui permettent de traiter des eaux usées par combinaison d'un floculant et d'un tensioactif. L'ajout conjoint du floculant à un tensioactif anionique, cationique ou non-ionique, produit une meilleure séparation de contaminants dans les eaux usées pour donner de l'eau pure ou extrêmement pure. Un rapport optimal entre le floculant et le tensioactif appliqué permet de réduire la quantité de floculant requise pour traiter les eaux usées.
