Hydrated lime CaOH 2 is also known as calcium hydroxide or slaked lime. Hydrated lime can be added to water as it is without requiring any special equipment, so it is a popular choice for small water treatment plants. In contrast, quicklime CaO, also known as calcium oxide or unslaked lime, must be slaked before it is used. Slaking is the ...
Additionally a sample of the quick or hydrated lime can be treated with phenolthalein indicator. This will turn bright pink if the sample is substantially quick or hydrated lime, but become weakly pink or not change colour if the lime has substantially carbonated. Note that these two indicative tests would work best with high calcium lime.

Throughout the manufacturing process, we carefully monitor process control to produce a high-calcium quicklime that is highly reactive and has an exceptionally high particle surface
A method of producing a hydrated lime. The process hydrates quicklime in conjunction with standard means of hydrating lime. The resulting hydrated lime has highly reduced contents of calcium oxide and magnesium oxide. The hydrated lime has little to no remaining reactivity when placed in contact with water after the process.
Hydrated Lime is produced by hydrating quicklime to produce calcium oxide which has small particle size, good flow properties, high surface area, and high total and available calcium hydroxide. Hydrated lime is used primarily in water and wastewater treatment, asphalt concrete treatment for anti-strip purposes, soil amendment processing, among other environmental applications.
