Hi Wayne, there was a good paper explaining a 10 cubic meter batch digester built for research. It was published by FAL in Switzerland and you can get it off the Departement of Energy. Search for documents with the topic of anaerobic digestion and you should find it there. I think it was made around early 2000. Other than that, you can get consultants in Germany and Netherlands that used a dry AD digester and then a CSTR in series. I think the company was Archea. It may have changed name though but you'll be able to track it down. It might be a bit more pricier because its made in stainless steel.
Post your updates on the list!
