Sodium Bisulfite 40% Solution for RO Plants
For RO plants, sodium bisulfite is typically injected into the RO feed stream upstream of the membrane system.
The purpose is to reduce residual oxidants such as free chlorine to a level compatible with the membrane manufacturer's requirements.
Important: Dosage should not be selected solely from a generic percentage. It should be calculated from the actual chlorine/oxidant concentration, water flow rate, product concentration and required residual level.
