DECHLORINATION

TESTING APPLICATIONS: DECHLORINATION

When chlorinated water is discharged in a flow test, it can drain into lakes, rivers and streams and harm aquatic life. According to AWWA, “Water released into the environment shall meet the applicable federal, state, provincial or local regulatory agency’s residual chlorine limit.” Your authority having jurisdiction provides dechlorination requirements.

Where do I find more information on dechlorination?

  • ANSI/AWWA C655-09 standard for field dechlorination
  • Product Manual for Dechlor Demon

How does it work?

A portion of the water flowing through the Dechlor Demon™ is diverted through the bypass into a mixing tank, where it is combined with a concentrated dechlorinating agent. The bypass flow is controlled by a precision indicating valve. The concentrate is reintroduced into the Dechlor Demon and hose, where it continues to mix with the flowing water. The chlorine is neutralized by the time it exits the hose.

  • 4″ Dechlor Demon Assembly

    Ideal for neutralizing chlorine in water, during testing or flushing a hydrant though a 4″ connection without affecting flow test results or adding stress to hydrant nozzles.

  • 4 ½” Dechlor Demon Assembly

    Ideal for neutralizing chlorine in water, during testing or flushing a hydrant though a 4 ½” connection without affecting flow test results or adding stress to hydrant nozzles.

  • Dechlorination Agent
