This course is 4 weeks in duration.

Learning Method:

  • The PDDP program is more of a self-guided learning style.

  • You are required to read the notes and materials given, complete the follow-up assignments on your own, send in your questions prior to your 1 hour webinar meeting (if required) and be involved in live discussion via the internet.

  • Once you have completed the course, you will receive a certificate of completion

Course description:
This course discusses special water purification methods using chemical and biological treatment processes. Topics include precipitation, oxidation-reduction, coagulation and flocculation, ion-exchange, disinfection, as well as wastewater treatment, microbiological consideration and biodegradation kinetics. Biological treatment processes such as activated sludge, sequencing batch reactors, aerated lagoons, trickling filters, biological nutrient removal, and tertiary wastewater treatment will also be addressed.

Course objective:

The participants will learn about the application, mechanisms of operation and design of chemical and biological processes used in water and wastewater treatment operations.

Target audience:

This course addresses water treatment methods and discusses the application and design of chemical and biological processes used in water and wastewater treatment operations. It will be most beneficial to technical Professionals and Planners who have some background, training and experience in these areas and wish to advance their knowledge in the area of water treatment. May also appeal to: Environmental Engineers, Consulting Engineers, Environmental Educators, Industrial Staff, Technicians and Technologists, Municipal Planners.

After you attend this course/workshop, you will be able to:
  • Understand the principles of chemical and biological processes and techniques for the removal of organic and inorganic contaminants from contaminated water and wastewater
  • Demonstrate the mechanisms and design aspects of water and wastewater treatment processes
  • Apply the gained knowledge of various chemical and biological processes to water and wastewater treatment projects
