Abstract

See full text

A slurry product is shown for treating water to both soften the water and to remove silica. The slurry is prepared by blending, in an aqueous medium, hydrated lime under the form of a slurry or of a powder with at least partly hydrated dolime, or magnesium hydroxide or magnesium oxide particles or a combination thereof under the form of a slurry or of a powder, to form an aqueous slurry where the amounts of the dolime, magnesium hydroxide or magnesium oxide particles or the combination thereof are provided such that the solid content of the slurry is up to 60% by weight of the slurry. The slurry also maintains a stable and pumpable viscosity for over a month.
