Odor Emissions from Anaerobically Digested Biosolids during Onsite Storage and Land Application: Impacts of Lime Dosing and the Type of Dewatering Process Used (Belt Presses versus Centrifuges)

Odor emissions data were collected during a Biosolids Fecal Coliform Regrowth Study in order to gain insight into odor emissions from anaerobically digested biosolids stored on site and during land application. Sampling and concentration analyses were completed for the following: odor (in terms of dilutions to threshold), ammonia, speciated sulfur compounds, volatile organic compounds, speciated amine compounds, and volatile organic acids. The effects of liming centrifuge dewatered biosolids were assessed, and comparison was made of belt filter press-dewatered versus centrifuge-dewatered biosolids.
