In the cellulose and paper industry this inorganic reagent is used to reduce chlorine residues in the cellulose production process.
The main application of this compound occurs in the treatment of water that is released from the production process in cellulose plants, as flocculant in the treatment of sanitary water and as a sticker in the paper industry.
