A composition based on lime comprising at least one mineral agent consisting of slaked lime in the solid phase and of an organic polymer incorporated into said solid phase, a method for its making and the use for its application in the treatment of water and sludge, in particular for conditioning sludge before dewatering.

Lime-based compositions, method for making them and their use in treating water and sludge

The invention relates to a slaked lime composition containing Ca(OH)particles of platelet crystalline morphology, called platelets, said platelets having a diameter D, this being the diameter of the circle circumscribing the platelet, a thickness e and an aspect ratio given by the ratio of said diameter of the platelet-circumscribing circle to said thickness, said composition having a platelet content of between 50 and 100% relative to the sum of the Ca(OH)particles and said aspect ratio being between 10 and 300, and to its manufacturing process.
