Hydrofluorosilic Acid (FSA or HFS)
Hydrofluorosilicic Acid, also known as FSA or HFS, is a transparent, colorless (water white to straw yellow), aqueous solution that is used in a variety of applications. One of its most common uses is in the fluoridation of water. FSA is produced during the concentration of phosphoric acid in an evaporation process unique to the phosphate industry. The vapor stream from the phosphoric acid reaction is scrubbed with water to form FSA from the naturally occurring silica and fluorine in the phosphoric acid. The final product is collected, stored and tested prior to release for shipment. Mosaic's FSA meets or exceeds ANSI/AWWA Standard B703 and is registered through ANSI/NSF60 for use in drinking water.
