Cleaning water pipes and reverse osmosis membranes in desalinization equipment as it is an antibacterial.
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.

Food Preservative
Antimicrobial	Sodium metabisulfite is commonly used as a food preservative for dried foods, as well as fruit concentrate juices. Sodium metabisulfite acts as an antimicrobial, inhibiting the growth of fungi and bacteria, thereby keeping food fresh and safe.
	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.

Other Uses
Medicinal	Sodium metabisulfite is an antioxidant additive in inject able medicines and is also used as a reducing agent in pharmaceuticals.
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.
