Digester Operation
  • The process of filling the NE side of the digester was started on the 29th of November and completed in mid December, 2006.
    • During the process, half of the collected manure was feed to the NE side of the digester with the remaining half being feed to the SW side of the digester that had already produced biogas for at least four weeks.
    • The effluent from the SW side of the digester was also pumped into the NE side of the digester to provide the inoculant to startup the anaerobic digestion process as well as fill up the NE side of the digester as quickly as possible.

Digester Operation (continued…)
  • Production of biogas started soon after the two sides of the digester were filled with the effluent from the dairy complex.
  • Biogas production became consistent starting from December 17, 2006.
  • Flaring the biogas started on December 20, 2006, and went on until the internal combustion engine/generator set was started briefly on the 9th of January, 2007.

Digester Operation (continued…)
  • Flaring the biogas continued until the interconnect with the power grid was approved and the combined heat and power generation (CHP) system was authorized to start on February 27, 2007.
  • The system has been in operation since February 28, 2007. It has been consistently generating electrical power since that date.
