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 chlorne. |
| 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. |
