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.
