25kg Sodium Sulfite (Na₂SO₃) – Ultra-Pure, High-Efficiency for Water Dechlorination, Food Preservation & Industrial Processes
As a trusted global chemical supplier, we offers 25kg Sodium Sulfite – a 99%+ purity, moisture-resistant powder engineered for water treatment, food safety, and industrial redox reactions.



Why Choose Our 25kg Sodium Sulfite?
99%+ High Purity
● Ultra-clean formula with <0.01% impurities (e.g., iron, lead) for critical applications.
● Anhydrous (0% water content) = no caking and 12+ month shelf life in storage.
Fast-Acting & Eco-Friendly
● Neutralizes chlorine in water (1.47g removes 1g Cl₂) to protect aquatic ecosystems.
● Biodegradable and non-toxic (complies with EPA, EU, and WHO safety standards).
Cost-Effective Bulk Packaging
● 25kg heavy-duty bags with UV-resistant coating and anti-caking liner to prevent clumping.
● Pallet-optimized (40 bags/1MT) for 35% lower freight costs vs. 1kg/5kg packs.
