Nitrate removal from groundwater by cooperating heterotrophic with autotrophic denitrification in a biofilm–electrode reactor

► Intensified biofilm–electrode reactor using cooperative denitrification is developed. ► IBER combines heterotrophic and autotrophic denitrification. ► CO 2 formed by heterotrophic denitrification is used by autotrophic bacteria. ► Optimum running conditions are C/N = 0.75, HRT = 8 h, and I = 40 mA...
