Free Poster: Explore The Chlorine Curve In Drinking Water

Utilities face from time to time confusing issues, like unexplained drop in residual, chlorine values dropping even though the dose has been increased or total chlorine value but no free chlorine value.
These types of issues can result from changes in the source water or treatment process and the risk may be invisible if the utility is not aware of where it sits on the chlorine curve.
To help unlock the mystery, we have created a wall poster on Chlorination in Drinking water, with:
  • Key chemical reactions
  • Signs and consequence of nitrification
  • Control strategies
  • And much more…
