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.
