Possible substrates are acetic acid, glucose etc. without any ex-proof requirements. In case of non observing limit values, methanol and ethanol feeding is appropriate to increase denitrification rate. But if the substrate is overfed, it will not be completely consumed by the biological process which will result in elevated effluent biochemical oxygen demand concentrations.
