Lime Use in Wastewater Treatment: Design and Cost Data
Lime Use in Wastewater Treatment: Design and Cost Data

Quicklime does not react uniformly when applied directly to water or wastewater but must first be converted to the hydrate Ca (OH)2. Hydrated lime or slaked lime is a dry powder obtained by a chemical reaction that occurs when sufficient water is added to quicklime to satisfy its affinity for water.

calcium oxide, but is mined as limestone (CaCO3) and then heated in kilns to produce ,quicklime, (CaO). It can then be slaked, or hydrated, to produce slaked/hydrated lime (Ca(OH)2). It is in the form of ,quicklime, or slaked lime that lime is most commonly used in water and ,wastewater, treatment applications (Water Quality and Treatment, 1990).

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.

Adding Lime to Seawater | HowStuffWorks

Because lime is a strong alkali capable of neutralizing acids, it's also used to treat soil, drinking water, wastewater and industrial acid streams. For years, scientists have considered it a possible solution for increasing the alkalinity of seawater, and conversely, lowering the growing acidity level.
