  • Stimulant sensitive flocculation and consolidation
    Patent number: 9174860
    Abstract: 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.
    Type: Grant
    Filed: December 22, 2011
    Date of Patent: November 3, 2015
    Assignee: Newcastle Innovation Limited
    Inventors: George V. Franks, Graeme John Jameson, Yao-de Yan, Simon Richard Biggs
