Environmental tradeoffs of denitrifying woodchip bioreactors
… quality standards, innovative practices like woodchip tile bioreactors, constructed wetlands, drainage water management systems, and riparian buffer strips for treating agricultural drainage water are continually being developed and implemented across the Midwestern United States. Like …

Denitrifying woodchip bioreactors for aquaculture manifold design and potential water reuse
… technology. Early studies on denitrifying woodchip bioreactors, a biological nitrate-remediation system, have demonstrated their potential for RAS wastewater treatment. Bioreactors are highly effective at nitrate removal via the process of denitrification but have also demonstrated a …

Denitrification of saline agricultural effluents (brine from groundwater desalination plants and agricultural leachates) in woodchip bioreactors in the SE of Spain
[SPA] El Campo de Cartagena (1316 km2) se localiza en la Región de Murcia (sureste de España) y es una de las principales cuencas dedicadas a la agricultura intensiva de regadío en Europa. A pesar deser un territorio de clima semiárido (temperatura media anual 18 ̊C; precipitación media anual ≈300 …

Challenges and Opportunities for Denitrifying Bioreactors in the Mid-Atlantic
… 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 organic …

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 …

Impact of Substrate on Nutrient Removal in In-Ditch Bioreactors
… eutrophication in the receiving waters. In-ditch bioreactors are a simple, inexpensive treatment technology that could potentially remove nitrogen and phosphorus from agricultural runoff. In-ditch bioreactors are intended to reduce flow rate and stimulate denitrification and sedimentation. Using …

Biogeochemistry of denitrifying bioreactors to enhance phosphorus removal from agricultural subsurface drainage
… pollution in surface waters. Denitrifying bioreactors (DBRs) are a prominent edge-of-field treatment technology to mitigate surface water nitrate loadings from agricultural subsurface drainage. Recent studies have identified that subsurface drainage can also contribute to the loss of …

Bioreactor-biochar (B2) treatment system: A novel design for efficient water pollution control from agri-drainage
… impacts of drainage, such as denitrifying woodchip bioreactor and phosphate removal structure. The research presented in this dissertation aims to introduce and design an innovative edge-of-field technology that enables the control of water pollution from tile drainage using woodchip …

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 …

Carbon dosing of denitrifying bioreactors to remove nitrate from agricultural drainage
… studies have demonstrated that denitrifying woodchips bioreactors effectively remove nitrate from a broad spectrum of wastewater. Even though bioreactors have a comparatively small spatial footprint and are straightforward to construct, the low long-term nitrate removal efficiency they …
