In wastewater treatment, H2SO4 is used to filter impurities, as well as improve the taste of water, neutralize pH in water, and to remove Mg2⁺, Ca2+ ions present in wastewater.
In fertilizer production, Sulfuric Acid is mainly used in the production of Phosphoric Acid, which is used in the production of phosphate fertilizers, and also in the production of Ammonium Sulfate.
In industrial production, Sulfuric Acid is widely used in metal production processes such as copper and zinc production and used in steel surface cleaning and rust removal solutions.
In addition, Sulfuric Acid is also used to produce aluminum sulfate (e.g. paper alum). Sulfuric Acid is also used in the production of sulfate salts, cleaning of metals before plating, and manufacturing of explosives, plastics, dyes, as well as pharmaceuticals. When mixed with water, it is used as electrolytes in a variety of batteries, lead acid, etc.
