Brenntag Mid-South Inc. is the City’s supplier for Sodium bisulfite.  Sodium bisulfite is used as a disinfectant solution neutralizer at the Rock Creek Wastewater Treatment Facility. After the waste stream has been disinfected using sodium hypochlorite, sodium bisulfite is introduced to neutralize the hypochlorite (which is harmful to aquatic life if not neutralized).  

This supplier, and the chemicals they provide are vital to the operation of the Rock Creek Wastewater Treatment Facility and its’ ability to maintain compliance. The Sodium bisulfite will neutralize all concentrations of hypochlorite in the waste stream so that they are not reintroduced into the receiving stream.

Rock Creek Wastewater Treatment Facility orders this product in 1600-gallon quantities approximately once every 6 weeks depending on weather, waste strength, and other factors.  Operations and Lab personnel communicate daily about the adjustable amount of chemical needed to maintain compliance.
