  • Denitrification in wood chip bioreactors at different water flows

    Subsurface drainage in agricultural watersheds exports a large quantity of nitrate-nitrogen (NO3–N) and concentrations frequently exceed 10 mg L–1. A laboratory column study was conducted to investigate the ability of a wood chip bioreactor to promote denitrification under mean water flow rates of 2.9, 6.6, 8.7 and 13.6 cm d–1 which are representative of flows entering subsurface drainage tiles. ...
