Bioreactor

A woodchip bioreactor removes nitrates from tile drainage. The woodchips act as a carbon source for denitrifying bacteria, and as they become saturated, low oxygen conditions promote denitrification.

Simple woodchip-filled trenches called bioreactors can clean nitrogen pollution from water. Find out more from Dr. Laura Christianson of the University of Illinois as she talks about one of her favorite ideas.

NRCS Bioreactor Video

In the summer of 2017, the Peoria County Soil and Water Conservation District (SWCD), the USDA Natural Resources Conservation Service (NRCS) and Illinois Farm Bureau teamed up with a forward-thinking landowner to plan, design, and install a relatively new conservation drainage practice so that folks could see what the denitrifying bioreactor looks like and how it’s built. Check out this video and see if it’s something that would fit on your land!
