UV or Dechlorination of Wastewater - Eliminating Residual Chlorine Concerns

Course No. C-2014

Credit: 2 PDH

Course Fee: $57.90 Purchase course

Subject Matter Expert: Jeffrey Havelin, P.E., BS CE, B.S.C.E.

Overview

Chlorination has been widely used as a germicidal agent in the final treatment of wastewater since the passage of the 1972 Federal Water Pollution Act-FWPA. Recent changes in regulations are mandating reduced chlorine levels in wastewater outflows since studies have indicated that chlorine can be toxic to aquatic life and harmful to the shellfish industry.

This course will introduce the student to UV disinfection as an alternative, which will totally eliminate the use of chlorine and all concerns about the Total Residual Chlorine TRC levels. This course will also introduce the student to the optional dechlorination process, which will chemically remove total dissolved chlorine from wastewater before it enters the outflow pipe.

If you are involved with wastewater treatment and you wish to become familiar with dechlorination procedures and UV treatment or you are concerned about reduction of TRC levels, this course will provide you with basic information you will need.

This course will review the basics of UV treatment of wastewater, which eliminates the chlorination process, and dechlorination procedures, which will reduce the TRC levels to an acceptable range.

The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to earn PDH credits.

 

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • Understand how UV exposure effects the cells of infectious agents
  • Review the basic types of UV reactor configurations
  • Discuss the optimum wavelengths and intensities required for germicidal use of UV
  • Review wastewater characteristics, which affect UV disinfection performance
  • Review actual case studies on existing treatment plants
  • Chemistry of dechlorination by sulfonation
  • Required equipment for gaseous sulfonation
  • Learn how to estimate daily required dosage of SO2
  • Review use of sulfite salts in lieu of gaseous sulfonation
