Germicidal Treatment of Wastewater Effluent - Eliminate TRC Concerns

Jeffrey Havelin, PE

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 (Total Residual Chlorine) TRC levels, this course will provide you with basic information you will need.

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 also 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.

This course is based entirely on the following (2) two EPA documents entitled: “Wastewater Technology Fact Sheet -Ultraviolet Disinfection” Publication - EPA 832-F-99-064 and “Wastewater Technology Fact- Dechlorination” Publication- EPA 832-F-00-022. This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials. You will be quizzed on the attached (2) documents in their entirety.
