Sodium Metabisulfite Applications
Water Treatment
Sodium Metabisulfite is commonly used as a reducing and dechlorinating agent in industrial water treatment.
It can be used for removing residual chlorine and in certain water-treatment processes where reducing conditions are required.
Mining & Mineral Processing
SMBS is used in certain mineral flotation and mineral-processing systems as a reagent for controlling flotation conditions and mineral separation.
The appropriate dosage and reagent combination depend on the ore characteristics and flotation process.
Food Processing
Food Grade Sodium Metabisulfite can be used in permitted food-processing applications as a preservative and antioxidant, helping control oxidation and maintain product quality.
The appropriate grade and dosage should be determined according to the food application and applicable regulations.
Pulp & Paper Industry
Sodium Metabisulfite is used in pulp and paper processing for various reducing, dechlorination and process-control applications.
Textile Industry
SMBS can be used in textile processing and dyeing operations as a reducing agent and for certain bleaching or dechlorination processes.
Chemical Manufacturing
Sodium Metabisulfite can also be used as a reducing agent, antioxidant or chemical intermediate in various industrial processes.
How to Choose the Right SMBS
The appropriate Sodium Metabisulfite grade and specification depends on the final application.
For industrial applications, buyers should consider factors such as:
Application → Required Purity → Technical Standard → Packaging → Annual Consumption → Destination Market
