HIGH CALCIUM HYDRATED LIME | Environment | Carmeuse

High calcium ,hydrated lime, is one of the most effective reagents for ,acid neutralization, and pH adjustment. These characteristics along with the presence of calcium assists in the removal of a wide variety of contaminants from water to improve the quality and keep customers and the environment safe. ,Hydrated lime, releases very little exothermic heat when in contact with water making it easy ...

Hydrated Lime, Slurry: A very common product, also known as ,hydrated lime, or CaO quicklime, ,lime, can be ‘slurry-ized’ through the addition of water to dry ,lime, powder. This slurry can be used to treat ,wastewater, to increase pH and alkalinity and is commonly used in potable water to “soften,” or remove hardness minerals, such as calcium and magnesium from drinking water.
