Product Usage

Sodium Chlorite is a highly efficient oxidizing and bleaching agent that plays an irreplaceable role in modern industrial hygiene and production. In the paper and textile industries, it serves as a core chemical for bleaching wood pulp, cotton, and fibers, providing superior whiteness without compromising fiber strength. In the field of water treatment, it is the primary precursor for generating Chlorine Dioxide ($ClO_{2}$), widely used for drinking water disinfection, algae control in industrial cooling systems, and sterilization of food processing equipment. Additionally, sodium chlorite excels in leather processing, metal surface treatment, and as a disinfectant and deodorizer in medical and healthcare applications.
