This two day course introduces biological nutrient removal (BNR) processes used by wastewater treatment plants around the world. One of the major water quality issues facing many jurisdictions is the enrichment of surface waters with nutrients such as phosphorous (P) and nitrogen (N). Although they are essential components of healthy ecosystems and are naturally widespread in the environment, human activity introduces them into the aquatic system. This leads to increased growth of algae, and other aquatic plants, which can impair fish and wildlife habitat, cause taste and odour problems in drinking water and threaten humans, livestock, pets, aquatic life, and wildlife.
This course offers assistance for wastewater operators as they prepare for an increasingly important technology in the wastewater industry. Participants will have increased knowledge of the important concepts related to BNR systems and a general understanding of how to operate one.

Note: If you have previously taken this course through Edmonton Waste Management Centre of Excellence (EWMCE) please be aware of the CEU implications of retaking the same course. Contact Alberta Environment for information.
The course is divided into four sections:
-Introduction to BNR
-Different BNR Configurations
-Operation and Control
By the end of this course you will be able to:
•Describe why removing nutrients from wastewater is important.
•Describe the technologies that are currently available to remove nutrients from wastewater.
•Explain the basic theory of biological nutrient removal (BNR).
•Explain the conventional activated sludge (AS) process
•Differentiate the AS process from BNR.
•Identify BNR configurations and outline differentiating characteristics.
•Explain the function of each zone within a BNR configuration.
•Recognize types of fixed film BNR configurations.
•Describe key operating parameters of BNR.
•Explain the function of the secondary clarifiers and fermenters.
•Explain daily operations including sampling and monitoring.
•Identify critical steps in BNR start-up.
•Identify commonly observed problems in a BNR system.
•Troubleshoot common BNR system problems.
No manuals will be forwarded to students in advance of this course – the instructor will provide all material on-site.
