Case Study: Food Waste Digester Upset

• Digester troubleshooting, recovery, and ongoing support
• Identified root cause of failure and worked with owner to formulate a feedstock blend to recover the digester operations and prevent future upsets
• Following recovery, Azura taught the owner how to self-manage their feed blend recipe
• Long-term support includes quarterly preventative monitoring
• Facility achieved 80% production in 2 months

“A dead digester, not producing any gas, that’s what go us to start working with Azura. Starting with detailed laboratory testing, Dave’s processes pinpointed the problem and got our digester back to 80% production in only two months. Azura’s ongoing monitoring had us hit full production a few weeks after that. Once we were stable, they developed a feedstock recipe to maintain stable production. We have high methane content, and no foam. Since then, even with engine issues we’ve averaged more than 90% production. Their emphasis on better testing for better decisions really pays off.”
