Potable Water - Disinfection

Course No. C-2008

Credit: 2 PDH

Course Fee: $57.90 Purchase course

Subject Matter Expert: Edward P. Brunet, Jr., P.E.

Overview

Disinfection is used to kill or inactivate disease-causing organisms in a potable water supply. The EPA Surface Water Treatment Rule (SWTR) requires systems using public water supplies from either surface water or groundwater under the direct influence of surface water to disinfect the water.

There are a number of different disinfection options available to the design engineer. The oldest and most widely used method of disinfection is the use of chlorine. Chlorine is very effective as a disinfectant, but can produce undesirable disinfection by-products. Newer disinfection technologies, such as ozone and UV disinfection, produce little or no disinfection by-products. However, these technologies have a disadvantage relative to chlorine in that they provide no residual disinfection in the water distribution system after initial treatment. Thus, recontamination is a concern unless chlorine is used as a secondary disinfectant to provide residual protection.

In this course the student will review the technical briefs Disinfection, Ozone, and Ultraviolet Disinfection published by the National Drinking Water Clearinghouse. This course is particularly relevant to engineers involved in the design and selection of water treating and/or distribution systems, as well as engineers who are simply interested in learning more about disinfection of potable water systems.

The student must take a multiple-choice quiz consisting of fifteen questions at the end of this course to obtain PDH credits.

 

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • Why disinfection of potable water is necessary
  • The regulatory requirements for disinfection of potable water
  • The different forms of chlorine available and their relative advantages and disadvantages for use as a potable water disinfectant
  • The advantages and limitations of using ozone as a disinfectant and the methods for producing ozone on-site
  • The advantages and limitations of using UV disinfection, as well as the major components of a UV unit.
