This 60-minute seminar will provide 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 will present a suite of proven technologies that can be employed to automatically control disinfectant residual levels in real world water distribution systems.

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