Chloramination: Practical Strategies For Reliable Water Quality

Chloramination delivers longer-lasting residuals and fewer disinfection byproducts, but only when it is run with discipline. Under the Stage 2 D/DBP Rule, locational running annual averages mean a trouble spot at a distal point cannot be averaged away. Warm weather and high water age raise the odds of nitrification, which becomes a feedback loop that is hard to reverse once it starts. Tight ratio and pH control, monitoring trended from plant to distal sites, and staged responses are what keep it in check. Calibration and documentation get their own scrutiny, since regulators treat undocumented work as work not done. Read the monitoring and response steps.
