Sodium Bisulfite, 1 L



Sodium bisulfite (also known as bisulfite bleach or sodium hydrogen sulfite) is a reducing disinfectant.

It can function as a disinfectant where oxidizing disinfectants are not an option. It will neutralize residual chlorine in chlorinated water and can also destroy hydrogen peroxide, chlorine dioxide, and other oxidants/disinfectants. Sodium bisulfite can also prevent oxidative corrosion in pipelines, cooling towers, or boilers, where it will destroy oxygen and other chemical oxidants.

We sell a 32% sodium bisulfite solution in 1 L and 20 L containers.

If you wish to purchase our products in a 20 L container or require our product’s MSDS, please contact us.
