Abstract

L'invention concerne un procédé et une composition pour déshydrater les boues. Ce procédé consiste à traiter les boues à l'aide d'un adjuvant de floculation et d'un floculant après quoi les boues sont déshydratées. Ce procédé se caractérise en ce que l'adjuvant de floculation est un composé inorganique ; l'adjuvant de floculation et le floculant sont prévus sous forme de composition solide à raison de 0,1 10 parties en poids d'adjuvant de floculation en partie par poids d'un floculant ; de l'eau est ajoutée à la composition pour fournir une solution aqueuse ou une dispersion de la composition . Cette composition aqueuse est ajoutée à la boue et la boue est ensuite déshydratée. Cette composition se caractérise en ce qu'elle comprend un mélange d'un adjuvant de floculation inorganique solide avec un floculant solide selon un rapport de 0,1 à 10 parties en poids d'un adjuvant de floculation en partie en poids de floculant.
