Webinar: Expanding the Role of Denitrification Bioreactors in Nutrient Reduction

May 23, 2022

The Iowa Learning Farms (ILF) conservation webinar taking place June 1 at noon CDT will feature Iowa State University Ph.D. candidate, Lindsey Hartfiel. Hartfiel is recognized for her work with engineered systems for water quality, with a particular focus on denitrification bioreactors for nitrate reduction. Her research goals focus on engineering of conservation systems to maximize positive impacts, identify new benefits, and reduce the risk of unintended byproducts or outcomes.

n the webinar, “Pumped Denitrification Bioreactor System for Treatment Beyond Subsurface Drainage,” Hartfiel will provide an overview of how denitrification bioreactors function and how they can be utilized for treatments beyond the typical use with subsurface drainage. She will also present highlights from a case study of a pumped bioreactor in Iowa. Details about site selection, the modified design of the bioreactor, expected performance improvements, and the monitoring and further study plans for the site.

“The common perception of bioreactors is that they are utilized primarily for subsurface drainage treatment in the high-flow drainage season, but we are encouraging a much broader view of these highly-effective denitrification structures,” said Hartfiel. “When engineered for use beyond this typical model to take advantage of the flexibility and functions of denitrification bioreactors, we expect they can play an even larger role in achieving the goals of the Iowa Nutrient Reduction Strategy to reduce the loss of nutrients and improve water quality.”

Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
