-
Biogas to Electricity
Methane is collected from the two stages of the AD vessel and utilized for fuel in combined heat and power (CHP) gensets. Typically power is sold at a higher rate than purchased, and much more is produced than consumed.
-
Biosolids
DVO digesters provide a superior animal bedding material, high "P" transportable/saleable fertilizers, soil aeration and peat-moss amendments.
-
Liquid Nutrients
The digestion process not only preserves the nutrient value in the manure, it also removes the odor, kills most pathogens (including E-Coli) and changes the state of the nutrients so they can be applied to a growing crop.
-
Phosphorus Recovery
Up to 90% of phosphorus can be economically captured, in a form that is economical to transport to the land that needs it (and away from sensitive watersheds).
-
Nitrogen Recovery
DVO's Nitrogen Recovery process captures the nitrogen ammonia that is otherwise lost, and places it in the form of a stable commercial fertilizer – creating another revenue source (or operating cost offset) for the digester.
-
Heat Energy
30-60% of the heat generated is used by the AD system. The remaining energy can be used as a replacement for hot water production (reducing natural gas or propane consumption), biosolids drying, in-floor heating of facilities, etc.
-
Biofuels – bioCNG
Biogas can now be economically cleaned, purified and pressurized to fuel semi-trucks, construction equipment, commercial fleets, farm vehicles etc.
-
Water Recycle/Re-Use
Water is increasingly a scarce and valuable resource. Options are available to not only sequester nutrients, but return process water to a reusable condition.

Why DVO? It’s simple. Their system digests ALL the waste from a dairy. Nothing bypasses. The manure is thoroughly and efficiently processed, and the gas output is steady and predictable year-round. Together this means significantly more biogas ‘per cow’ is produced than with other digester designs. DVO also has an excellent track record of success. These things are good for the environment and the local community...and tend to make our investors happy too.”
“It also helps that dairy farmers already know DVO, and they like the other benefits the DVO system offers them.” -
The digester is one of the few things we have ever purchased that has exceeded our expectations."
-
When a business such as ours makes an investment of this size the concensus from our family was to go with the proven technology. For us that meant DVO."

DVO took care of all details from writing grants to helping with design and installing the last manure pump. They have my philosophy of keeping things as simple as possible on the farm. However the most important part of their company are the people. Simply a great group to work with."
