The High Density Sludge (HDS) Process and Sulphate

2015-4-17  Lime dissolution is the first step of the neutralisation process. For large treatment systems, quicklime is used. This lime must first be hydrated (slaked) and is normally fed to the process as a slurry. When fed to the process, the hydrated lime then dissolves to increase pH. The two following equations illustrate these reactions: CaO + H 2

Limestone vs Quicklime - What's the difference? WikiDiff

As nouns the difference between limestone and quicklime is that limestone is (mineralogy) an abundant rock of marine and fresh-water sediments; primarily composed of calcite (caco₃); it occurs in a variety of forms, both crystalline and amorphous while quicklime is lime, (calcium oxide ), produced by heating limestone; on treatment with water it gives slaked lime.
