Evoqua provides a range of odor and corrosion control products that can be fed directly into the wastewater stream to remove hydrogen sulfide

Q: How does hydrogen sulfide cause corrosion?
Hydrogen sulfide (H2S) is typically known for causing odor in wastewater collection systems. However, beneath the surface hydrogen sulfide converts to sulfuric acid, corroding sewer pipes and weakening concrete structures.

Q: What is the impact on the collection system?
When left untreated, sulfuric acid breaks down infrastructure, shortening the life of wastewater treatment systems and potentially resulting in dangerous sewer collapses and overflows. A study done by the U.S. EPA found that over 80 percent of sewer collapses were due to hydrogen sulfide corrosion.

This leads to unexpected costs for infrastructure repair or replacement, as well as public exposure and health concerns.

Q: How can corrosion be mitigated?
There are a variety of solutions to prevent corrosion, from pipe linings and coatings to less corrosive materials of design. These methods will prevent the surface from corroding, but fail to address the cause of the problem, including odor issues.

Evoqua provides a range of odor and corrosion control products that can be fed directly into the wastewater stream to remove hydrogen sulfide. This method prevents H2S gas from being released into the collection system, effectively mitigating corrosion and odor. 

Q: What solutions can Evoqua provide to address corrosion?
Evoqua has several innovative products that address corrosion and odor, and provide additional benefits in wastewater collection systems.

  • Bioxide Solution – prevents and removes sulfide and treats multiple odor compounds.
  • Alkagen Solution – prevents the release of H2S by raising the pH of wastewater. Also reduces the impact of FOG and provides a beneficial alkaline supplement.
  • Odophos Iron Salt Solution – prevents corrosion by precipitating sulfide in wastewater and aids in the removal of phosphorous and solids.
  • Hydrogen peroxide – prevents corrosion by oxidizing sulfide in wastewater.

Q: What are the next steps?
Contact Evoqua to schedule a system evaluation. Our technical experts will measure current H2S levels, flows and system dynamics to determine the best solution for your application. Proactively treating corrosion will extend the life of your wastewater system and significantly reduce the risk of costly repairs.
