Sodium Bisulfite Oxygen Scavenger
Sodium bisulfite (NaHSO3) is a cost-effective chemical oxygen scavenger used in boiler feedwater, hot water systems, and reverse osmosis membrane pre-treatment for dechlorination. It rapidly reacts with dissolved oxygen to prevent corrosion in boiler circuits. In RO applications, it neutralizes residual chlorine to protect thin-film composite membranes from oxidative damage.
