Sodium Metabisulfite – ≥97% Pure SMBS for Dechlorination, RO Membrane Preservation, Food Processing, Wine-Making & Industrial Use | 22.7 Kg Bag

Sodium Metabisulfite | 22.7 Kg Bag – Premium Grade for Water Treatment, Preservation & Industrial Use

Our Premium Sodium Metabisulfite (SMBS), supplied in a 22.7 kg (50 lb) bag, is a versatile, high-purity chemical widely used in water treatment, food preservation, wine-making, and industrial processes. With ≥97% purity, this fine crystalline powder delivers consistent, reliable performance as a dechlorination agent, antioxidant, and oxygen scavenger.

In water treatment, SMBS is primarily used for chlorine removal and as a preservative for reverse osmosis (RO) membranes. It works by scavenging dissolved oxygen, helping prevent the growth of aerobic microorganisms during system shutdowns or storage. Please note: sodium metabisulfite is not a disinfectant and should not be used for cleaning membranes.
