Title
(EN) STIMULANT SENSITIVE FLOCCULATION AND CONSOLIDATION
(FR) FLOCULATION ET CONSOLIDATION REAGISSANT A UN STIMULANT
Abstract
(EN) The present invention relates to methods for the separation of materials from heterogeneous fluids and provides a means of effecting stimulant-sensitive flocculation and consolidation of solid suspensions within a liquid medium. Specifically, the present invention provides a method of controlling the state of a suspension of solid particles in a liquid, including applying to the suspension a stimulus adapted to control inter-particle forces between the solid particles. The stimulus is reversibly operable to control attraction and/or repulsion. Means of consolidating a sediment bed and of separating the resultant liquids-rich and solids-rich phases are also within the ambit of the invention.
(FR) La présente invention concerne des procédés de séparation des matières de fluides hétérogènes, et notamment, une façon d'obtenir une floculation ainsi qu'une consolidation réagissant à des stimulants, la floculation et la consolidation portant sur des solides en suspension dans un milieu liquide. L'invention concerne plus particulièrement un procédé permettant de contrôler l'état d'une suspension de particules solides dans un liquide. A cet effet, on applique à la suspension une stimulation conçue pour adapter des forces interparticulaires entre les particules solides. Cette stimulation est utilisable de façon réversible de façon à commander l'attraction et/ou la répulsion. L'invention concerne enfin des procédés permettant de consolider un lit sédimentaire et de séparer les phases résultantes selon qu'elles sont riches en liquides et riches en solides.
