Microbiology of Anaerobic Digesters (2/10/2026)
Price range: $102 through $123
The microbiology of anaerobic digesters is a complex mix of bacteria and methanogens. Understanding these organisms and testing is essential to process control decisions.
All registrants will need to come to this LearnH2O course page on the day of the course to access the Zoom link.
Microbiology of the Anaerobic Digester provides an overview of the bacteria and methanogens involved in methanogenesis. The overview includes hydrolysis, fermentation, acetogenesis and methane-production. Start-up, recovery from inhibition and toxicity, acceptable operational conditions and monitoring requirements are review. Monitoring requirements include not only digester sludge but also digester feed sludge. Attention is placed upon specific monitoring requirements for 1) biogas analysis, 2) ORP, 3) temperature and pH, 4) % VSS, 5) minor and critical nutrients and 6) digester decant. A check list of analytical tests for identifying an unstable anaerobic digester is provided.
Each operator must be able to log into Zoom individually with a single device for Contact Hours**.
Prior to class, attendees will need their own zoom account which includes their own name, phone number and email address. Multiple accounts can not be made with the same email address.
Attendees can use a computer, phone, or tablet to attend program, however, for the best experience, a device with a web cam and speaker is best.
