Abstract

Disclosed herein is a method and a system for controlling N2O emission from a water-based solution containing nitrifying organisms, wherein an input variable for a controller is the ratio between NO3 - produced and NH4 + oxidized as determined by measuring NO3 - and NH4 + concentration both at the inlet and at the outlet of the aerated section containing the water-based solution with nitrifying organisms and a scaled output variable is obtained from the controller as a function of said ratio by a non-linear algorithm, so that the oxygen input and/or the aeration time is varied based on an integration of the deviations of said output variable.
