Abstract

L'invention concerne un procédé permettant de clarifier, de déshydrater, ou d'améliorer la rétention et l'écoulement d'eaux industrielles ou de compositions de fabrication, et ce à l'aide d'une quantité efficace d'au moins une dispersion d'un floculant polymère cationique hydrosoluble, l'amélioration consistant à ajouter ce polymère, qui présente une concentration d'au moins vingt-cinq pour cent, aux eaux usées ou à la composition de fabrication. Les eaux industrielles sont de préférence des eaux usées de transformation alimentaire, des eaux usées huileuses, des eaux usées de papeterie, et des eaux usées inorganiques contaminées, la composition de fabrication pouvant être une suspension cellulosique aqueuse.
