This course has met the requirements under O. Reg. 128/04 as Director Approved Continuing Education.

After participating in this course, you will be able to:

• Understand principles of chemical and biological processes and techniques for the removal of organic and inorganic contaminants from contaminated water and wastewater
• Learn about the technologies that are commonly used in industrial water and wastewater treatment operations
• Develop a better understanding of the mechanisms and design aspects of water and wastewater treatment processes
• Apply your knowledge of various chemical and biological technologies to water and wastewater treatment projects

Description:
This course discusses chemical and biological processes and their applications in industrial operations and environmental engineering practices. It addresses mechanisms, operation principles and applications of pertinent processes used in the removal of organic and inorganic contaminants from contaminated water and wastewater, including coagulation and flocculation, oxidation-reduction, chemical precipitation, water softening, ion exchange, activated sludge, trickling filters, rotating biological contactors and lagoons. Case studies will be presented and discussed throughout the course.
