drinking Water treatment: neutralisation and/or remineralisation
Using this equation, one can calculate that, in order to increase mineralisation (M-alk. and CaH) by 1°F, 8.8 mg · L –1 of CO 2 and 7.4 mg · L –1 of pure hydrated lime (or 5.6 mg · L –1 of pure quicklime) have to be injected into the water. CO 2. Industrially, CO 2 is supplied in cylinders under a very high pressure and more generally in cooled "low pressure" containers.

What Is Lime Used For In Water Treatment?
Lime is a manufactured product made from limestone (calcium carbonate) or dolomite (calcium magnesium carbonate). The raw material is processed into quicklime and hydrated lime. Since it is alkaline, it's often used to adjust the pH of water and soils containing acidic components. It's used to treat both drinking water and wastewater.
