Hydrogen Sulfide Control

A fast growing municipality was experiencing elevated levels of hydrogen sulfide in the sewer collection system, resulting in numerous public nuisance odor complaints. H₂S levels were recorded as high 1300 PPM at various locations within the sewer system. A site was chosen that demonstrated elevated levels.

An NanO₂ was installed with integrated oxygen generator with (2) discharge zones. One zone is dedicated to the wet well and operates either on time or DO demand to maintain a positive DO, with an average flow rate of 3-6 USGPM. The second zone discharges into the pump discharge line a flow of 6 USGPM into the collection system when the lift station pumps activate.

• Eliminates stripping from aqueous solution to nuisance and hazardous odors
• Rapid dissolved oxygen delivery effective in preventing conditions that produce odors
• Inline injection assist in reducing sewer pipe corrosion
• Low operating costs, minimal operator requirements
