Exploring a pumped bioreactor system for improved water quality

September 30, 2022  By Liz Ripley | Iowa Learning Farms and Water Rocks!

Recent innovations that may extend bioreactor applications will be discussed during a virtual field day with Iowa Learning Farms and the Iowa Nutrient Research Center and the Conservation Learning Group, Thursday, Oct. 20 at 1 p.m.

The event will feature a live conversation with Iowa State University Ph.D. candidate Lindsey Hartfiel; Michelle Soupir, professor and associate chair for research, department of agricultural and biosystems engineering, Iowa State University; and Natasha Hoover, water quality research scientist at Iowa State University.

Iowa Learning Farms is a part of Iowa State University Extension and Outreach.

In recent years, bioreactors have shown themselves to be efficient and dynamic tools for improving water quality through denitrification. Now, a new innovation suggests an additional use for these bioreactors, even when water isn’t flowing from the field tile drainage. This new design is a pumped bioreactor system with a pilot project installed just outside Ames.


Pumping water through a bioreactor allows it to be used beyond the seasonal patterns of subsurface drainage, extend its use to new applications and very possibly extend the life of the bioreactor itself. This virtual field day will explore the results of the design and discuss future plans for the project.

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