Title:  Woodchip bioreactors for improved water quality

Location:  Iowa State University Ag Engineering and Agronomy Farm, Boone, IA

Time Period:  2017-2018

Research Team:  Michelle Soupir, Natasha Hoover, Thomas Moorman, Thomas Isenhart, Morgan Davis and Emily Martin

Project Description:  This research was completed at the pilot-scale bioreactor system that was installed in 2014, and focused on building on the knowledge of kinetics and mechanisms for nitrate removal in woodchip bioreactors and identified flow conditions that may contribute to potential negative impacts such incomplete denitrification resulting in potential greenhouse gas emissions. Analysis and evaluation of the results of this study are ongoing, and will continue to add to the body of knowledge about woodchip bioreactors.
