This is a 2-part online course. You must complete both parts to receive Contact Hours. 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.

Zoom information and student guide are included in your order confirmation.

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 name, phone number and 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.

**Attendees can share a computer for viewing. But, each attendee must also log into a device individually (e.g. View on computer at the plant as a group, but also log into Zoom individually with your phone). Attendees must individually answer periodic poll questions and take quizzes during program. This is necessary to verify attendance and participation. This will involve typing into a device.
