Anaerobic Digestion


1.2 CEUs


This two day course introduces anaerobic digesters and the digestion process increasingly used by wastewater treatment plants.

One of the major aims in wastewater treatment is to stabilize treated wastewater products and reduce harmful pathogens that can reside in wastewater sludge. Anaerobic digestion is a means to reduce these pathogens, thereby stabilizing sludge. As well as reducing pathogens levels, sludge stabilization reduces odours, and reduces the potential for the sludge and biosolids to further decay. Digestion is one method to stabilize raw sludge to create safe biosolids for beneficial use.

The goal of this course is to give wastewater operators an overview of the anaerobic digestion process to support you to manage this important process.

As you go through this course, consider the following questions:
• Would an anaerobic digestion system at your plant change your role as an operator, or if you have an anaerobic digester, how has it changed your role?
• Are you taking the steps necessary to maximize the effectiveness of your anaerobic digester?
• Are you taking steps to minimize hazards and monitor the effectiveness of your digester?

Consider changes in responsibilities, schedules, and knowledge as you think about these questions.


Note: If you have previously taken this course through Edmonton Waste Management Centre of Excellence (EWMCE) you cannot receive CEUs again.

By the end of this course, you will be able to:
• Describe how the stabilization process fits into total plant operations
• Outline the rationale for stabilizing sludge.
• Identify stabilization alternatives to anaerobic digestion and the advantages and disadvantages of each.
• Explain the science of anaerobic digestion.
• Describe key operating parameters of anaerobic digestion.
• Identify common types of anaerobic digester configurations and list the advantages and disadvantages of each.
• Understand alternatives for digester operation including temperature of operation and continuous or batch feed approaches.
• Identify the major components within an anaerobic digestion system.
• Explain the function of each major component within an anaerobic digestion system.
• Identify typical auxiliary equipment within an anaerobic digestion system, and their function.
• Describe basic daily operations and start up procedures
• List types of samples required for monitoring your digester.
• Identify and prevent potential hazards of digestion.
• Troubleshoot common anaerobic digestion system problems.

No manuals will be forwarded to students in advance of this course – the instructor will provide all material on-site.
