Germicidal Treatment of Wastewater Effluent-Eliminate TRC Concerns
Jeffrey Havelin, P.E.
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.
This course reviews the following topics:
This course would be very informative for engineers who are involved with the design, or operation of sewage treatment facilities.
Benefit for Attendee
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, when chlorine is used as a germicidal agent.
This course will review germicidal procedures, which engineers who are involved with the design, or operation of sewage treatment facilities would use in the final treatment of wastewater effluent.
The course will
review dechlorination procedures, which will reduce the TRC levels to an acceptable
range when chlorine is used as a germicidal agent, and it will also review UV
treatment as a germicide.
This course is based entirely on the two following EPA documents.
need to open or download above documents to study this course.
At the completion of this class the design professional will be informed about UV disinfection procedures, and optional germicidal treatment with chlorine which typically requires subsequent dechlorination treatment.
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
