  • Use of partly prehydrated lime for separating a solid matter/liquid mixture, method for treating sludge and purified sludge obtained by said method
    Patent number: 8013204
    Abstract: A novel use of delayed reactivity partly prehydrated lime (“DRQL”), which is comprised of 40 to 98% by weight of CaO and of 60 to 2% by weight of Ca(OH)2, preferably of 80 to 92% by weight of CaO and of 20 to 8% by weight of Ca(OH)2, and more preferably of 85 to 90% by weight of CaO and of 15 to 10% by weight of Ca(OH)2, in the field of the separation of solid matter from the liquid of a suspension. The invention also involves a novel method for treating a sludge, in which the solid matter is concentrated, dried and recovered using the delayed reactivity partly prehydrated lime. It additionally relates to, as a novel industrial product, the purified sludge obtained according to the method.

  • Use of Partly Pre-Hydrated Lime for Separating a Mixture of Solid/Liquid Matters, Method for Treating Sludge and Purified Sludge Obtained by Said Method
    Publication number: 20080028811
    Abstract: The present invention relates to a novel use of delayed reactivity partly prehydrated lime (abbreviated to: “DRQL”), which is composed of 40 to 98% by weight of CaO and of 60 to 2% by weight of Ca(OH)2, preferably of 80 to 92% by weight of CaO and of 20 to 8% by weight of Ca(OH)2, and better still of 85 to 90% by weight of CaO and of 15 to 10% by weight of Ca(OH)2, in the field of the separation of solid matter from the liquid of a suspension. It also relates to a method for treating a sludge, in which the solid matter is concentrated, dried and recovered using said delayed reactivity partly prehydrated lime. Finally it relates to, as a novel industrial product, the purified sludge obtained according to this method.
