On August 21st the SE MN Nutrient Management Specialists Dawn Bernau and Katie Richards toured the Dane County Community Anaerobic Digester as part of the 2012 North American Manure Expo held in Prairie du Sac, Wisconsin August 21-22, 2012. The Dane County Community Digester is the only operating community digester in Wisconsin. Three dairies contribute to this digester and it is owned and operated by Clear Horizons, Inc. This is a unique strategy in which the company owns and operates the digester and the producers contribute manure as feedstock. This is also a unique situation to have three dairies so close together each being within 2000 feet of the digester. The three dairies total 3,000 animals. The manure from each farm is pumped through underground pipes into a reception tank at the digester site. The manure is then fed into the digester with additional substrates which are trucked to the facility.

What does the digester consist of? It is comprised of three general collection systems: 1) Figure 1, underground manure lines to a reception tank; 2) Figure 1, an above ground tank for storage of additional wastes; and 3) Figure 2, a below ground open pit for manure and additional feedstock reception. In Figure 3 there are three digestion tanks, Figure 4 two 1MW generators, Figure 5 a solid/liquid separation system, and Figure 6 the control room.

What are the digesters fed? They are fed a blend of organic feedstocks. The majority of the feedstock consists of the manure from the dairy farms, about 90 percent by volume. The additional 10 percent is other organic feedstocks such as food waste. The three 1.2 million gallon digester tanks (figure 3) produce the biogas which rises to the top of the digester tank that has storage within the inflated roof. The biogas produced is then sent to the two 1MW generators (totaling 2MW)(figure 4) where it is used to produce electricity. The electricity is sold to the local utility. The Dane County Community Digester produces enough electricity to power approximately 2,500 homes. Following digestion, the digestate is sent to the solid/liquid separator where the solids are removed by a centrifuge (the only one used in the Midwest) and the liquids are sent back to a holding tank. The liquids have enough nutrients left in them to provide the three dairies with a good source of fertilizer for their cro .....
