SMBS (Sodium Metabisulphite)

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.
