Lime in Water Treatment | Graymont

Lime is used by many municipalities to improve water quality, especially for water softening and arsenic removal. Indeed, the American Water Works Association has issued standards that provide for the use of lime in drinking water treatment. Softening - In water softening, hydrated lime is used to remove carbonate "hardness" from the water.

How does weathering affect limestone?

 · Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere. Burning fossil fuels also contributes to this.

Wet lime scrubbing | EMIS

Process description. The wet lime injection process combines the advantages of scrubbers and (semi) dry lime injection. This flue gas cleaning technique is mainly used for desulphurisation of flue gases, while other acid-forming components are also bonded. During wet lime injection, a slurry of limestone (CaCO 3) is sprayed into the spray column.
