(1977) US Systems: Covered lagoon digester at pig farm in North Carolina (1998) US Systems:A 250-gallon oil tank digester set in a solar shed in Wisconsin by Al Rutan (1978) US Systems: Construction of a fiberglass digester at a Wisconsin workshop led by Al Rutan (1978) US Systems: A simple 4” valve on a smaller-scale system in Missouri (1983) US Systems: Pennsylvania State University (1979) – the base or well for a gobar gas plant design system for dairy manures – constructed off-the-shelf silo parts. US Systems: Lancaster Co,. Penna (1987) — Dried digested solids ready for land application US Systems:Overflow storage pond for chicken system in Wisconsin (1977) Beware — Overloading the pond with nutrients can burn surrounding plants. US Systems: Cornell University (1977) – plug-flow digester diagram US Systems: A caveat! Remains of scavenged fuel-tank digesters after barn burned down around them in Missouri. (1983) (The fire was said to have been unrelated to the digesters – it would have exploded instead of just burned.) Methane at 4 to 14 % in air is very dangerous for explosions. Just don’t let it happen. You’al will certainly smell it — And it can be monitored. US Systems: Gas storage at Mason-Dixon Dairy near Gettysburg, Pennsylvania. (1986) One of two large plug-flow digesters. System handles manure from 1200 milking cattle and provides electricity for farm operations plus income of $40,000 per month from local electric company.Please click on image for a larger view US Systems: Mason-Dixon Dairy digester hardware system for securing gas storage cover to trench liner (1986) US Systems: Lancaster Co., Penna (1987) — The operations shed for an almost wholly underground digester system generating electricity US Systems: Covered culvert with equipment shed and rubber membrane in pond for gas storage at the Wisconsin dairy (1977)Share this:Click to share on Facebook (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on Pinterest (Opens in new window)Click to email this to a friend (Opens in new window)
