Laboratory investigation of flow and chemical behavior of woodchips to better understand performance of denitrifying bioreactors

  • Topic
    Microbial conversion of nitrate (NO3-) into gaseous nitrogen (N2), also known as denitrification, is facilitated by high organic carbon contents and permanently saturated conditions. Denitrification in woodchip bioreactors has the ability to reduce the agricultural load of nitrate into the environment, addressing the rising problem of eutrophication of natural water bodies.

    The aim of this work is to characterize the different chemical behavior of woodchips with different particle sizes and to investigate the effect of retention time on NO3- removal under different flow rates.
