The composition of wastewater from dairy processing plants makes it highly suitable for biological wastewater treatment processing. As well anaerobic biological treatment of the wastewater there is also the option of applying anaerobic biological processes. By applying anaerobic technology a large part of the organic load in the wastewater can be removed and converted into energy-rich biogas. In addition, the anaerobic technology can be used in dairies to produce biogas from waste whey. The biogas which is generated can be used to produce electrical and/or thermal energy.
About the Project
The Roberto R. Bustamante Wastewater Treatment Plant began serving the east, southeast, and Lower Valley parts of the city in 1991 and has a treatment capacity of 39 MGD.
About the Project
In 2011, the City began work on a cogeneration facility as part of the upgrades at the Waste Water Treatment Plant. The city was given us the ability to convert solids arriving at the Waste Water Treatment Plant into useful energy and high quality fertilizer. The system was designed to generate about 750,000 kWh per year, which translates into about $50,000 annually in saved utility costs. The fertilizer produced is spread over the City’s wheat field (see below) to reduce the amount of...
About the Project
The Fond du Lac Regional Wastewater Facility modified it’s biogas handling system in 2012 to include a process to biologically removal hydrogen sulfide; physical adsorption of siloxane compounds; moisture removal, a new biogas-fueled engine and a liquid storage system for receiving hauled in high-strength waste.
The methane produced by the anaerobic digesters is cleaned so it can be efficiently burned in the new engine generator and produce electricity. The electricity produced by the...

Several powerful incentives are driving biogas generators to consider upgrading their biogas to meet standards for pipeline injection and vehicle fuel markets. Producing renewable natural gas (RNG) can create opportunities to monetize lucrative RIN, or renewable identification number, credits under the federal Renewable Fuel Standard and generate carbon credits under state supported low carbon fuel standards.
As each biogas project is unique it can be a challenge to determine the best gas upgrading technology...
