MISCOwater - Lime Slakers

Lime Slakers. Lime Slaking is the process of mixing quicklime (calcium oxide, CaO) with water to form hydrated lime (calcium hydroxide CaOH2), using excess water to produce a slurry. The reaction of quicklime and water is exothermic and will produce 491 BTUs per pound of CaO and form 1.32 pounds of calcium hydroxide.

Lime - Wastewater Treatment - Eurocode Standards

Quicklime, CaO, has a density range of approximately 55 to 75 lb/cu ft, and a molecular weight of 56.08. A slurry for feeding, called milk of lime, can be prepared with up to 45 percent solids. Lime is only slightly soluble, and both lime dust and slurries are caustic in nature. A saturated solution of lime has a pH of about 12.4.
