This guideline on anaerobic digestion (AD) has been prepared using the expertise and experience of members of the Canadian Biogas Association (CBA). Azura was pleased to be able to provide technical contribution, overall review, and editing by David Ellis, utilizing his almost 30 years of experience working with anaerobic digestion systems.
An food waste digester case study from Azura Associates was incorporated into the training material presented by anaerobic digester experts Dr. Melanie Hecht and Birgit Pfeifer at the IBBK’s virtual Biogas Operator Training in June of 2020. Dr. Hecht, who is a Senior Biogas Plant Biology and Process Control Expert, presented a section called “Practical Plant Operation: Process Control and Plant Optimization” at this event. This case study highlighted the methodology used by Azura to recognize imbalances and proactively adjust the digester feedstock recipe to balance its nutrition for optimal biogas production, performance, and consistency.
David Ellis presented a methodology developed specifically to optimize anaerobic digestion systems at the Value of Biogas Webinar Series hosted by the Canadian Biogas Association (CBA) in June 2020.
Azura’s David Ellis presented a case study of helping a farm-based digester as a part of Dr. Daniel Zitomer’s anaerobic digestion online short course. The case study focused on the importance of testing and knowing what additional data to look for in digestor remediation. The study also shares some empirical guideline values for LCFA concentrations in digester as determined by years of LCFA testing done by Azura.
