Sodium Bisulphite

Sodium Bisulphite (NaHSO3) is an inorganic compound primarily used as a reducing agent and preservative in industrial processes. It typically appears as a white to pale yellow crystalline powder and is supplied in standard 25 kg bags, with options for bulk supply upon request. This chemical is usually provided at a purity level suitable for water treatment and industrial-grade applications, ensuring effective performance in its designated roles. Buyers should note that Sodium Bisulphite is sensitive to moisture and should be stored in a cool, dry, and well-ventilated area to prevent caking and degradation. Commonly, Sodium Bisulphite is dosed in water treatment systems at 10-50 mg/L for dechlorination purposes, highlighting its role in neutralizing residual chlorine in wastewater streams. It is incompatible with strong oxidizers, which can cause hazardous reactions, hence separate storage is essential to maintain safety. Understanding these handling and dosage specifics is crucial for procurement and operational planning.

In water treatment, residual chlorine must be effectively removed to prevent damage to aquatic life and to make treated water safe for reuse or discharge. Sodium Bisulphite acts by chemically reducing chlorine to chloride ions, thus eliminating the toxicity associated with free chlorine. This control is essential to meet environmental discharge standards and maintain system integrity. Furthermore, sodium bisulphite's role as an antioxidant and preservative extends to stabilizing products in food processing and protecting fibers in textile manufacturing. Accurate dosing and proper handling ensure process efficiency and product quality, reducing operational risks and compliance issues in industrial environments.
