DVO Introduces Advanced Phosphorus Recovery System
Wisconsin Ag Connection - 05/28/2015

The Chilton-based DVO, Inc., which is an engineering company that designs anaerobic digesters, has introduced a simple and practical solution that removes 75 to 95 percent of phosphorus from anaerobically-digested wastes.

The group announced this week that they have successfully commissioned the system for a large dairy farm in the northwest, as well as for a commercial mixed-waste facility in Indiana and a dedicated poultry litter digester in Ohio.

Farm and commercial bio-wastes can contribute to excess phosphorus in the environment. By treating these wastes in the company's new patented Two-Stage Mixed Plug Flow anaerobic digester and then employing this new phosphorus recovery system, landowners can conserve and recycle this valuable resource while protecting our natural waterways.

"Not only is DVO's PR system a low-maintenance, sustainable treatment solution that works for agriculture and industry, it also provides real benefits for the environment," said Doug VanOrnum, vice president Strategy and Technology. "Largely because these plant-ready fertilizers and micronutrients are captured in a form that can now be safely transported and utilized in areas that need them."

VanOrnum says operating costs for this new phosphorus recovery system average one-eighth of a penny per gallon of liquid processed. The phosphorus-rich solids generated the system can be easily transported from the area and are marketable as a soil amendment, fertilizer or potting soil/peat moss replacement.
