Used in water treatment to adjust pH and remove impurities by promoting coagulation and precipitation of contaminants. Commonly applied in wastewater treatment plants to neutralize acidic water and reduce corrosion in distribution systems. Utilized in flue gas desulfurization to remove sulfur dioxide from industrial exhaust gases. Plays a role in soil stabilization for construction by reducing soil acidity and improving load-bearing capacity. Employed in the paper and pulp industry for regenerating sodium hydroxide in the kraft process. Also used in agriculture to amend acidic soils and improve crop growth conditions.
