Tulsa

The City of Tulsa, OK had a problem with THM formation. Because they operated their system at a pH of 8.3, excess sodium hypochlorite was needed to produce free chlorine residuals. They confirmed through a study that a reduction in pH would result in less THMs. However, they feared a reduction in pH would result in higher levels of corrosion. Using SeaQuest:

  • Lead corrosion rates were reduced by 65%
  • Copper corrosion rates were reduced by 47%
  • pH was reduced from 8.1 to 7.2

As a result, the tests showed the system could be operated at neutral pH to reduce disinfection byproducts (such as THMs) and actually have better corrosion control using SeaQuest.
