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.
