Drinking Water Disinfection with Online DPD Analyzers

Begins: 10 Feb 2022 12:00 AM EDT
Ends: 10 Feb 2022 1:00 PM EDT
Presenter(s): John Welsh and Justin King


Chlorine disinfection has become the most widely used solution for drinking water plants across the country. Careful dosing control is vital to thoroughly disinfect drinking water before it is distributed to the community. Over- or under-dosing can cause harm to the community served by the drinking water plant. Online chlorine analysis uses a DPD chlorine analyzer, which is a highly reliable method for monitoring residuals at the affluent and dosing control.

Online DPD chlorine analyzers that conform to standard method 4500-CL-G and US EPA method 334.0 can be used to report effluent limits to the EPA. In this webinar, learn how YSI’s 3017M DPD Chlorine Analyzer can be used for optimal online chlorine analysis and how it can be applied to various drinking water processes.

Attendees will be able to:

  1. Describe how chlorine removes pathogens from water and why it is the most common disinfection method.
  2. Explain chlorine behavior in drinking water and how to dose chlorine properly.
  3. Apply the 3017M to a drinking water treatment plant to monitor and control chlorine disinfection and monitor and report chlorine residuals.

Who should watch:

Water treatment engineers, operators, instrument technicians, and superintendents who want to learn more about chlorine disinfection with online DPD chlorine analyzers.
