Newtrient Comments/Opinions:

The DVO Two Stage Linear Vortex digester is a mixed plug flow design and is currently in operation on over 90 projects ranging in size from 500 to 15,000 head. The DVO system has evolved to be a reliable and efficient energy production platform on dairy manure. DVO has demonstrated a consistent commitment to the advancement, development and commercialization of anaerobic digestion and manure management technology. DVO is a founding member of the American Biogas Council (ABC) and active in the promotion of the dairy industry at all levels. DVO recently announced their first installation in Pennsylvania, bringing the number of states with a DVO digester to 19.  Its patented digester system has also been constructed in six foreign countries.  

Newtrient will continue to work with DVO to further refine the cost and performance information as more information comes in with new commercial dairy installations.
