Removal of SMBS (Sodium Methabisulfite) in wastewater

Good Morning,

I have some problems to remove SMBS in wastewater generated by the shrimp industries.

Does anybody have a wastewater treatment to suggest me ?

I have tried with Coagulation and floculation, but there was not a satisfied result.

I would although ask you if you have any information about the quantity of SMBS generated in the whole world.

Thanks in advance for any answer.

Wish you a good day !
