Notes

Sodium bisulfite is a food additive with E number E222

Chemical compound with formula NaHSO3.

On additon with water Sodium bisulfite releases sulfur dioxide gas, Which is resulting killing yeast, fungus, and bacteria, roughly 24 hours before fermentation, when added to wines.

It may also be added after fermentation to prevent vinegar production and protect the color and flavor of wine. It kills microbes and in fruit canning, prevents browning.

Sodium Bisulfite is also added to leafy green vegetables to preserve visual freshness of the greens. When adding to recipes to prevent oxidation, strive for 0.1% of  weight.  

Handling & precautions

Sodium Bisulfite 40% Solution

Sodium Bisulfite 40% Solution – Manufacturer & Supplier in UAE

Sodium Bisulfite 40% Solution is a concentrated aqueous solution of sodium bisulfite (NaHSO₃), widely used as a reducing agent, dechlorination chemical, oxygen scavenger and water-treatment chemical in industrial, marine and process-water applications.

It is supplied as a ready-to-use liquid solution for applications where controlled reduction of oxidizing agents, particularly residual chlorine, is required.

Sodium Bisulfite 40% Solution – Product Highlights

  • Concentration: 40% Sodium Bisulfite Solution

  • Chemical formula: NaHSO₃

  • Physical form: Liquid solution

  • Appearance: Typically clear to pale yellow liquid

  • Highly effective reducing agent

  • Used for chlorine and oxidant removal

  • Suitable for industrial water-treatment applications

  • Used in RO pretreatment systems

  • Useful for dechlorination of treated water

  • Suitable for industrial and marine applications

  • Available in bulk and industrial packaging

Major Applications

1. RO Water Treatment

Sodium Bisulfite 40% Solution is commonly used in reverse osmosis (RO) pretreatment to remove residual free chlorine before water reaches polyamide RO membranes.

This is important because free chlorine can damage or degrade chlorine-sensitive RO membrane materials.

2. Dechlorination

The product is widely used for reducing residual chlorine in:

  • Potable-water treatment processes

  • Industrial wastewater

  • Process water

  • RO feed water

  • Reclaimed water

  • Chemical treatment systems

3. Oxygen Scavenging

Sodium bisulfite can act as an oxygen scavenger in suitable water-treatment applications, helping reduce dissolved oxygen in systems where oxygen control is required.

Applications may include selected:

  • Boiler-water systems

  • Feed-water treatment

  • Industrial water circuits

  • Process-water systems

The actual treatment method and dosage should be established according to water chemistry and the applicable technical specification.

4. Industrial Chemical Processing

Sodium Bisulfite Solution is also used as a reducing agent in various chemical and industrial processes where controlled reduction is required.

5. Marine Applications

Sodium bisulfite can be used in marine and shipboard water-treatment applications, particularly where dechlorination or reduction of oxidizing residuals is required.
