Hydraulic evaluation of a denitrifying bioreactor with baffles
Denitrifying ‘woodchip’ bioreactors are an effective conservation practice to reduce nitrate-nitrogen (NO3-N) loss from tile drained agricultural areas. They enhance the naturally occurring denitrification process via the addition of woodchips and maintenance of anoxic conditions. Bioreactors tend …

Range of and relationships between physical and hydraulic properties of commonly available denitrifying bioreactor woodchips
… key physical parameters of woodchip media for denitrifying bioreactor design. Current design guidelines can be improved by analyzing more woodchip types and the effects of overburden on woodchip properties. The objectives of this study were to quantify and determine the relationships between …

Challenges and Opportunities for Denitrifying Bioreactors in the Mid-Atlantic
… over the last several decades have produced denitrifying bioreactors that harness the ability of ubiquitous soil microorganisms to convert bioavailable N into inert N gas, thereby removing bioavailable N from an ecosystem. Denitrifying bioreactors are edge-of-field structures that consist of …

Using Monte Carlo Analysis to Assess Outcome-based Payment for Environmental Services for Denitrifying Bioreactors in the Chesapeake Bay
… feasibility of measuring pollutant outcomes. Bioreactors, engineered sinks that convert biologically available forms of nitrogen into an inert form (N_2), have recently been proposed to treat and remove legacy nitrogen from springs (Easton et al., 2019). Since nitrogen removal can be directly …

Nitrous oxide and methane emissions from denitrifying bioreactors with and without a soil cover
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-08-01

Impact of Biochar Amendment, Hydraulic Retention Time, and Influent Concentration on N and P Removal in Horizontal Flow-Through Bioreactors
… and require management. In the mid-1990s, denitrifying bioreactors (DNBRs), a subsurface, edge-of-field best management practice (BMP) that intercepts and treats agricultural drainage by supporting nitrate-attenuating denitrification with a saturated, carbon-filled substrate, were …

Greenhouse Gas Production and Nutrient Reductions in Denitrifying Bioreactors
… promising avenue to reduce excess nitrogen, and denitrifying bioreactors (DNBRs) are an emerging technology harnessing this biochemical process. Previous DNBR research has established successful nitrate removal, whereas this study examines the potential to expand DNBR functionality to address …

Dissolved phosphorus removal in denitrifying bioreactors: field and laboratory studies
Denitrifying woodchip bioreactors are an edge of the field conservation practice designed to remove nitrate (N) from subsurface agricultural drainage water. However, phosphorus (P) removal has been observed in bioreactors across Illinois. Both N and P play an important role in eutrophication and …
