ABSTRACT:
In a biological wastewater treatment system, the addition of an intermittently aerated second bioreactor to accomplish ammonium oxidation to predominately nitrite and then to achieve denitrification by introducing the effluent, containing nitrite, from the second bioreactor into the influent collection system or the head works of a wastewater treatment plant. Denitrification from nitrite occurs in the collection pipe using the influent organics as a carbon source.
