Chlorine monitoring for basic chlorine disinfection control  

Measuring chlorine levels on-line or at the sample point is important to process control due to the instability of chlorine. Parameters include Free and Total Chlorine.

Free Chlorine  

Free Chlorine Monitoring

Although the pros and cons of disinfection with chlorine have been extensively debated, it remains the most widely used chemical for disinfection of water in the U.S. Chlorine is primarily used as a disinfectant, but also serves as an oxidizing agent for taste and odor control, prevention of algal growths, maintaining clear filter media, removal or ion and manganese, destruction of hydrogen sulfide and improving coagulation.

With analytical testing, you can:

  • Maximize disinfection efficiency
  • Determine adequate Chlorine CT credits
  • Optimize chlorine feed pump rates
  • Create an iron & manganese removal strategy
