Sodium Bisulfite- Industrial/Technical Grade

Sodium bisulfite is a fine crystallized sodium grain that releases sulfur gas when dissolved in liquid. Manufacturers use sodium bisulfite in foods, cleaning products and pharmaceutical research. Common uses for sodium bisulfite include food preservation and cleansing to sanitize equipment and kill mold, bacteria and germs. Additionally, metal workers use sodium bisulfite to finish metals.


Industrial/Technical Grade
Sodium Bisulfite is widely used in various industries.

1. Leather Industry: Sodium bisulfite is used as leather processing chemical to make finished leather products softer, wearable, waterproof and longer lasting.


2. Water Treatment: Sodium Bisulfite plays an important part in the treatment of water, wastewater and waste as a strong reducing agent. The chemical removal of dissolved oxygen by chemically treating with sodium bisulfite reduces the corrosion rate in steel material. Sodium bisulfite also assists in the dechlorination of drinking water as well as in the chlorine removal in waste waters. Another treatment method that utilizes sodium bisulfite's effectiveness is in the reduction of chromium. All three reactions allow for chemical removal to be controlled by the amount of sodium bisulfite that is reacted with the solution.

3. Medicine Industry: The medicine industry uses Sodium Bisulfite for manufacturing semifinished product of metamizole sodium and aminopyrine.

4. Rubber Industry: Sodium Bisulfite is used in Rubber Industry as coagulative agent.

5. Textiles Industry: Sodium bisulfite is an important component in the preparation of dye intermediates. There are also areas of substantial utilization in the processing of wool as well as for the antichlor treatment required of many textile products.

6. Chemical Industry: Sodium bisulfite is a common reducing agent in the chemical industries. In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor.

7. Photography Industry: Sodium bisulfite serves as dual purpose in photographic industry. It is responsible for preserving the thiosulfite in the fixing baths and scavenging the dissolved oxygen in the developer solution.

8. Water Pipes: Sodium bisulfite is also used in the process of purifying water, cleaning water pipes and reverse osmosis membranes in desalinization equipment as it is an antibacterial. It is usually added to large piping systems to prevent oxidative corrosion.
Food Grade
Food Grade sodium bisulfite is used to preserve and extend the shelf life of manufactured food items. As an additive, the food processing chemical helps to prevent the oxidation of fresh-cut produce.

It is used to preserve color and inhibit bacterial growth on fruits, vegetables, some seafood and wine.
Sodium bisulfite can preserve many of the qualities of fruits and vegetables, including the color, taste and nutritional value. It is a common ingredient used in the canning process; the sodium bisulfite protects the fruits and vegetables from oxidizing and changing color.
Sodium bisulfite is used in beverages, fillings, sauces, dressings.
Soft drink manufacturers use the pH-lowering properties of sodium bisulfite to reduce the tartness of many beverages.
It is also present in wines and beers, as it is used as both a sterilizer and an antioxidant in the process of brewing beer or fermenting wine.
Sodium bisulfite acts as bleacher (Sweet, pastry, water-soaked bamboo slices, etc.) loosening agent (bread, biscuit, etc.) corrosion resistance antiseptic (fruit juice, can, brewing, grain storage, etc.); antioxygen antistaling agent (acupuncture needle sprout, sea food, garden stuff, etc.)
