RXSOL-19-1524-050 is a Dechlorination product which is frequently used in municipal wastewater, pulp & paper, power, and textile water treatment plants and as a Oxygen scavenger in Boiler water treatment.
RXSOL-19-1524-050 also popuar for preservative in photo developer process and Food additive.
Its chemical reaction gives Flue gas desulfurization and Mild reducing agent in organic synthesis by Efficiently remove traces or excess amounts of bromine, iodine, osmate esters, chromium trioxide, and potassium permanganate
Sodium Bisulfite solution for using as chlorine reducing agent in RO units and for membranes preservation. Acts as Dechlorinating agent is a kind of rapid reaction, is used to remove the residual chlorine in the reverse osmosis water, suitable for all kinds of reverse osmosis membrane.
Sodium Bisulfite 40% Solution (NaHSO3) is a Pale Yellow Liquid.
Sodium bisulfite, sodium bisulphite, sodium hydrogen sulfite. Its molecular formula / chemical formula is NaHSO3.
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.

Sodium Bisulfite 40% Solution
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.
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
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.
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
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.
Sodium Bisulfite Solution is also used as a reducing agent in various chemical and industrial processes where controlled reduction is required.
Sodium bisulfite can be used in marine and shipboard water-treatment applications, particularly where dechlorination or reduction of oxidizing residuals is required.
