Abstract
L'invention concerne un procédé de séparation de boue qui implique l'ajout d'une suspension colloïdale minérale insoluble dans une boue industrielle pour déstabiliser la boue industrielle et séparer les composants déstabilisés de la boue industrielle. La suspension colloïdale minérale insoluble comprend de l'hydroxyde de magnésium. Dans un autre mode de réalisation, de l'hydroxyde de magnésium finement divisé sec peut être ajouté puis dispersé dans une boue industrielle. Des floculants et/ou coagulants classiques peuvent également être ajoutés. Des procédés de séparation physique classiques peuvent être utilisés pour séparer la boue industrielle déstabilisée.
