In Residual Chlorine Reduction of Wastewater Using UV or Dechlorination, you'll learn ...

  • Why it is important to reduce the amount of residual chlorine entering receiving waters from wastewater outflow pipes
  • Advantages and disadvantages of dechlorination and ultraviolet (UV) systems
  • How dechlorination by sulfonation works
  • Options for measuring residual chlorine levels
  • Factors that impact the effectiveness of UV disinfection systems

Length: 19 pages

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. 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. The course will also examine the optional dechlorination process, which chemically removes 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.
