Sodium Thiosulfate, Industrial Chlorine Remover for Water Treatment.

Product Overview

Our Sodium Thiosulfate (Na₂S₂O₃), commonly known as "Hypo" or photographic fixer, is a high-purity crystalline compound widely used in photographic processing, water treatment, and chemical industries. With excellent reducing properties and solubility, it serves as a versatile chemical across multiple applications.

Industrial-grade Sodium Thiosulfate, also known as "Hypo," plays an indispensable role in water treatment, renowned particularly for its efficient and economical dechlorination capabilities. When municipal tap water or industrial process water contains residual chlorine or hypochlorite, these oxidizing agents, while disinfecting, can severely harm subsequent processes—such as microbial fermentation, aquaculture—and sensitive chemical reactions or certain industrial products. Sodium Thiosulfate rapidly and thoroughly neutralizes chlorine's toxicity by engaging in a redox reaction, reducing it to harmless chloride ions. The reaction equation is straightforward: Na₂S₂O₃ + 4Cl₂ + 5H₂O → 2NaHSO₄ + 8HCl. This process is not only highly efficient but also yields products that are easy to manage, without introducing new toxic by-products. Consequently, it is widely used for dechlorinating drinking water, adjusting swimming pool water, pre-treating water before exchange in aquaculture, and protecting catalysts from chlorine poisoning in chemical production. Our product is manufactured from high-purity raw materials, featuring uniform crystals that dissolve quickly and react completely, ensuring you achieve stable and reliable dechlorination at a low cost. For use, the dosage must be calculated precisely based on the residual chlorine content, typically added as a drip-fed solution to achieve optimal results and prevent overdosing.
