Limestone for pH Adjustment in Industrial Wastewater

Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts.
