Sodium Bisulfite Solutions 30%, 40%
Sodium bisulfite 30% and 40% are aqueous solutions of sodium bisulfite, commonly used as a reducing agent, preservative, and in water treatment processes. This clear to pale yellow liquid has a strong sulfurous odor and is known for its ability to neutralize chlorine and bleach, requiring careful handling.
Sodium Bisulfite Solutions – Industrial Grades
Sodium bisulfite solutions come in different concentrations. Used in water treatment, food production, pulp and paper manufacturing, and photography. Good for oxygen scavenging, chlorine neutralization, and preservation.
What Is It?
Sodium bisulfite (NaHSO₃) is a white crystalline powder. Forms clear, slightly acidic solutions in water. Works as a reducing agent and antioxidant. Dissolves well. Also called sodium hydrogen sulfite. Removes dissolved oxygen and neutralizes chlorine in industrial processes.
Available Concentrations
We have two concentrations for different industrial needs.
30% Solution
The 30% grade works for water treatment, boiler oxygen scavenging, and preservative processes. Handles well. Used in municipal water treatment and food processing. Clear to slightly yellow liquid. Has a sulfur dioxide smell.
40% Solution
The 40% solution is for demanding applications. Pulp bleaching, heavy-duty oxygen scavenging, and large-scale chlorine neutralization. Works well in paper manufacturing and industrial water treatment when you need stronger chemical action.
Industrial Uses
These chemical solutions work as oxygen scavengers in boiler water treatment. Prevents corrosion and makes equipment last longer. Protects metal surfaces in closed-loop systems as a corrosion inhibitor. Neutralizes chlorine in wastewater treatment, swimming pools, and textile processing.
Benefits include fast oxygen removal, cost-effective corrosion protection, and reliable performance at different concentrations. Good pH buffering. Stable in various operating conditions.
