Since 1991, the New Belgium Brewing Company has been brewing delicious craft beer at its brewery in Fort Collins, Colorado, USA. New Belgium Brewing is the fourth-largest craft brewer in the United States and the eighth-largest brewery in the nation, producing popular brands including Fat Tire Belgian Ale, Voodoo Ranger IPA, and Citradelic IPA.
New Belgium Brewing’s core values include producing world-class beers and preserving environmental stewardship. As part of its sustainability efforts, New Belgium Brewing wanted a more responsible approach to managing its water. This included installing an on-site wastewater treatment system that would generate an effluent that far exceed the city’s discharge requirements.
Due to the limited amount of space available on-site and the fact that the facility is located near a residential area, the system needed to have a compact footprint and mitigate any odors associated with the wastewater treatment.
The AnMBR system consists of a 330,000 gallon continuously stirred tank reactor (CSTR) paired with an 86,000 gallon membrane tank. The system was designed to treat up to 142,000 gpd of wastewater and generate a final effluent with biochemical oxygen demand (BOD) and total suspended solids (TSS) concentrations of less than 230 mg/l.
