Abstract
In this work, a mathematical model has been set up to describe NO and N2O formation by autotrophic ammonium oxidizing bacteria in a partial nitritation (SHARON) reactor. Based on mechanistic grounds, two possible reaction mechanisms for NO and N2O formation were proposed. These two scenarios have subsequently been compared in a simulation study. The influence of intermittent versus continuous aeration on NO and N2O formation for the same aerated retention time has been addressed as well. Applying continuous aeration a maximal N2O formation was found at intermediate dissolved oxygen (DO) concentrations of about 2 mg O2.l-1.
