Webinar: Disinfectant Residual Control in Water Distribution Systems 

This webinar provided water system managers, operators and engineers a practical understanding of the conditions, chemistry and science behind affecting positive control of both chloramine and free-chlorine levels in water distribution systems.  Importantly, the second half of the seminar presented a suite of proven technologies that can be employed to automatically control disinfectant residual levels in real-world water distribution systems.

When:
April 18, 2024 at 1 PM EST (U.S.); Recording now available.

What to expect:

• Background on the importance of controlling disinfectant residual levels in water systems
  • Prevalence of low residual related MCL violations
  • AWWA 2017 Disinfection Survey results
• Nitrification
  
  • Role of nitrifying bacteria in the destruction of water quality (chloramine systems)
  • Operational procedures currently used to stave-off nitrification
  • Importance of temperature on water quality
• The Breakpoint Curve – Understanding Fluctuating Residual Levels in Networks
  • A simple explanation to a lot of chlorine based residual chemistry
  • Requirements to controlling setpoint on a breakpoint curve
• Equipment options and equipment form factors
  • Roles of tank mixing, chemical feed, real-time water quality analysis and feedback algorithms
• Case Studies:
  • Automatic control of chloramine residuals in water networks
  • Automatic control of chloramine residuals in water networks with multiple tanks
  • Controlling free-chlorine residual versus chloramine residual 

Who Should Attend:

• Water system managers
• Operators
• Engineers
