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 Attained

  · 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

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.
