From a fundamental biochemical perspective nitrous oxide (N2O) has the potential to be a useful real-time parameter to monitor nitrification kinetics and control aeration systems. This potential may be greatest in bioreactors operated in low dissolved oxygen (DO) conditions as a means to maximize aeration system oxygen transfer efficiency and minimize energy requirements and where DO data alone may prove ineffective as a simple monitoring/control parameter. To this end, the objectives of this paper are to (i) present the results of a detailed bench-scale study that investigated the N2O generation response of a bioreactor subjected to perturbations in wastewater ammonia and carbon loading, and related aeration system manipulations, and (ii) based on these findings and the established gas transfer characteristics of the bioreactor, describe a conceptual nitrification monitoring and aeration system control strategy based on a pattern recognition/neural network implementation framework.
