Sodium Metabisulfite (SMBS) Formula: Na2S2O5 CAS # 7681-57-4
Sodium Metabisulfite (SMBS) is used for water treatments in municipal wastewater treatment and industrial wastewater treatment and any water purification needs:
SMBS is used to remove Chlorine excess in water treatment. Its’ functions as an oxygen scavenger in order to eliminate dissolved oxygen from water. It is mainly used as reduction agent. It is used in the water treatment industry to quench residual chlorine. It is used in tint etching iron-based metal samples for microstructural analysis.
Also, when used to remove dissolved oxygen in wastewater, SMBS is effective as a preservative and oxygen scavenger that prevents growth of aerobic microorganisms.
Also, SMBS is a critical product used to remove cyanide from tailings of precious metals mining sites. It is used as an SO2 source (mixed with air or oxygen) for the destruction of cyanide in commercial gold cyanidation processes. It is used in the oil and gas industry as a corrosion inhibitor/oxygen scavenger. It is used in the mining industry for controlling depression of pyrites and sphalerite minerals.
