This work compares a pilot-scale H2-based membrane biofilm reactor (MBfR) and a pilot-scale packed-bed heterotrophic reactor (PBHR) for denitrification of nitrate-contaminated groundwater. The comparison includes the effluent water quality of the denitrification reactors (NO3−, NO2−, dissolved oxyge...
