The Chemistry of Corrosion
Under acidic or turbulent conditions, hydrogen sulfide is released from wastewater in the form of gas. Thiobacillus bacteria in the system oxidize the gas to form sulfuric acid, which corrodes sewer pipes and weakens concrete structures, shortening the life of your wastewater treatment system.
Microbial Induced Corrosion (MIC) in wastewater collection and treatment systems is a severe and on-going problem in the United States. In addition to the direct cost of replacing corroded infrastructure, there are hidden costs in lost time and labor which are diverted to emergency and repair activities, and not spent on core wastewater collection system operations. There are also dangers associated with leaking sewer pipes and street collapses.
Hydrogen sulfide corrodes sewer pipes and concrete structures
The good news is that, by updating your hydrogen sulfide treatment regimen, you can effectively prevent further corrosion in your sewer system, while also eliminating odors.
