Sodium Metabisulphite (SMBS) for Wastewater Treatment Detailed Product Description: Our Sodium Metabisulphite (SMBS, $Na_2S_2O_5$) is a high-purity technical reduction chemical widely utilized across industrial wastewater treatment infrastructures. It functions as a powerful reducing agent, particularly essential for the treatment of toxic electroplating effluents and industrial bleaching streams. Key Applications & Benefits: ● Hexavalent Chromium Reduction: Transforms hazardous $Cr^{6+}$ into safe $Cr^{3+}$, allowing it to be easily precipitated by lime or caustic soda. ● Dechlorination Agent: Rapidly neutralizes residual free chlorine or ozone in water before it reaches sensitive downstream biological reactors or RO membranes. ● Dissolved Oxygen Scavenging: Controls unwanted oxidation processes inside closed water circuits.
