Abstract

L'objet de l'invention concerne un produit et son procédé d'application pour l'épuration des saumures. Il est constitué par la combinaison d'une chaux de bonne qualité, à grande réactivité, provoquant une réaction rapide avec les espèces chimiques indésirables, qu'elle précipite avec un adjuvant solide tel le sulfate de calcium anhydre. Il est destiné à l'épuration des eaux salées concentrées pour la fabrication de la soude et du chlore.
