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:
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:
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.
