In addition, one of our previous works demonstrated that 99.5% nitrate removal could be achieved at a C/N ratio as low as 1.5 in a continuous-operation biofilm-electrode reactor with sodium acetate as the carbon source (Peng et al. 2015). In that case, the heterotrophic denitrification accounted for 92% of nitrate removal.
