Abstract

Selon ce procédé, on mélange 3 et 11 l'eau usée avec le solvant lourd, on sépare 4 et 12 l'émulsion formée pour obtenir de l'eau dégraissée, une petite quantité d'une émulsion d'eau et de solvant et le solvant chargé en matière grasse et en terres, on mélange 26 l'émulsion et le solvant et on déshydrate 27 ce mélange, on clarifie 13 le solvant anhydre pour séparer les terres, on soumet le solvant clarifié à une distillation azéotropique en présence d'eau 14 pour former une émulsion à partir de laquelle on peut récupérer la matière grasse et un produit de tête à partir duquel on peut régénérer le solvant. Ce procédé s'applique notamment aux eaux usées provenant du trempage, lavage et rinçage de la laine.
