Day 280: August 31. Manure pouring into the central pit from Harmony Dairy and at the same time the flexible tube to the right of the incoming stream is full indicating it is uploading manure into the digester.

FarmPower has built and is now operating an anaerobic digester in the Skagit Valley near Mount Vernon, Washington. The digester is between two dairy farms and captures manure to generate methane gas which will be used to generate electricity which will be purchased by Puget Sound Energy. Fertilizer and animal bedding materials are important by-products. The digester went on line on August 28, 2009. Andgar Corporation of Ferndale Washington is the general contractor. For information see http://www.farmpower.com or email: FarmPowerNW@gmail.com.

Bob Raymond > Rexville Digester Now! photo

Bob Raymond > FIRST, A LOOK AT THE SITE ON DAY 10.

Bob Raymond > Day 277: August 28. Generator fired up and producing electricity to the grid. Kevin and Daryl Maas point to the display showing the Kwh being produced. The generator was started at a lower RPM, but on Saturday, August 28 at 9am in the morning it was ramped up to the full 750 Kwh. More pictures of the event coming soon.

Bob Raymond > Day 280: August 31. Liquids from the end of the digester process and after the fiber has been removed pour back into the holding tank. This will be pumped back to the two dairies for use on the fields.

Bob Raymond > Day 276: August 27, 2009. Manure from the two farms flows into the central reception pit and then into the digester.

Bob Raymond > Day 280: August 31. Recently delivered whey at the substrate reception pit.

Bob Raymond > Day 280: August 31. Hydro-seeding all around all side of the digester. Using fiber as the hydro-seeding medium

Bob Raymond > Day 280: August 31. Manure at the end of its cycle through the digester passes through the separator. The fiber then goes through a press onto a conveyor and is dumped into a truck.

Bob Raymond > Day 276: August 27. A wheelbarrow full of fiber product from the Rexville digester.

Bob Raymond > Day 264: August 21. Flaring takes place while the digester is producing (large quantities of gas) and during final steps in preparation of the generator.

Bob Raymond > Day 280: August 1. No flaring at this point as generator is taking up to 200 CF/M of gas and generating up to 750Kw
