Product Description:
Used as a preservative in food and pharmaceutical industries to prevent oxidation and spoilage by removing dissolved oxygen from solutions. Commonly added to processed foods, beverages, and injectable medications to maintain stability and extend shelf life.
Widely applied in water treatment to dechlorinate drinking water and wastewater by neutralizing residual chlorine after disinfection. Helps protect downstream equipment and aquatic life from chlorine damage.
In the pulp and paper industry, it serves in sulfite pulping processes to break down lignin in wood, aiding in the production of paper. Also used in bleaching operations to improve brightness.
Acts as an oxygen scavenger in boiler feedwater systems in power plants, preventing corrosion in steam and condensate lines by removing dissolved oxygen.
Employed in chemical synthesis as a reducing agent in various industrial reactions, including dye manufacturing and organic compound purification.
