"Breakpoint Chlorination … Do you Really Have a Free Chlorine Residual?

Combined chloramine residuals often mask themselves as false-positive ‘phantom’ free chlorine residuals, while using the DPD free chlorine reagents and test method. A detailed breakpoint chlorine diagram will be used during this session to help visualize the pros and cons between using combined chloramine residuals or free chlorine disinfection methods.  Chloramination treatment, disinfection byproduct formation, nitrification, and controlling chlorine taste/odor will be addressed in this session. Attendees will receive formulas and tools, to return to the job and calculate chlorine demand, optimize chlorine dosage rate, and limit byproduct formation. Bring your own DPD chlorine field test kit, copies of your raw/finished water quality reports, and a sample of your finished water to see first hand if you have phantom false-positive chlorine residuals and how to avoid them and then make treatment changes to improve water quality and consumer confidence.
