3.Sodium Metabisulfite Application:
| Water Treatment | 1.Eliminating dissolved oxygen in waste water and in pipes; |
|
2.Cleaning water pipes and reverse osmosis membranes in desalinization equipment as it is an antibacterial. |
|
|
3.Sodium metabisulfite is used in water treatment plants to remove excess chlorine. |
|
| Bleaching Agent |
Sodium metabisulfite's functions as a bleaching agent, which is useful in making paper pulp, cotton and wool. |
| Photographic and film industry |
For preparing developer solutions, for acidifying fixing baths (photo grade). |
| Landscape Gardening |
Sodium metabisulfite used in landscape gardening as a tree stump remover, as it disintegrates the lignin -- chemicals in plant cell walls -- in the tree stumps, making them easier to remove. |
| Fiber Industry | In the sulphitisation of tanning extract. |
| Gold mining | For bleaching ground wood, as an antichlor. |
| Antimicrobial |
1.Sodium metabisulfite is commonly used as a food preservative for dried foods, as well as fruit concentrate juices. |
|
2.Sodium metabisulfite acts as an antimicrobial, inhibiting the growth of fungi and bacteria, thereby keeping food fresh and safe. |
|
|
3.In beer and wine manufacturing, sodium metabisulfite is used as both a sterilizer and an antioxidant in the process of brewing beer or fermenting wine. |
|
| Medicinal |
Sodium metabisulfite is an antioxidant additive in inject able medicines and is also used as a reducing agent in pharmaceuticals. |
