Microbiology of Anaerobic Digesters


  • April 19, 2022
    9:00 am - 12:30 pm

This class provides an overview of the bacteria and methanogens involved in methanogenesis. The overview includes hydrolysis, fermentation, acetogenesis, and methane production. We will review start up, recovery from inhibition and toxicity, acceptable operational conditions, and monitoring requirements. The monitoring requirements include not only digester sludge but also digester feed sludge. Attention is placed upon specific monitoring requirements for biogas analysis; ORP; temperature and pH; % VSS; minor and critical nutrients; and digester decant. A checklist of analytical tests for identifying an unstable anaerobic digester is provided.
