Over the past year, Carollo has been helping the City of Boulder in Colorado determine how best to optimize internal carbon and leverage affordable supplemental carbon sources to improve nitrogen reduction. The City has identified a possible partnership with Avery Brewery for the use of waste weak wort as a cost effective carbon supplement. Carollo has completed the design of aeration basin modifications and a carbon feed facility that will store and dose waste weak wort or acetic acid to the process. This facility should be operational in 2016.
