The interaction between activated sludge and a wastewater is subject t
o important changes. This is reflected not only in changing biokinetic
parameters but also in changing model structures. The need to select
the `right' model structure in a reliable way on the basis of respirog
raphic data provided by on-line sensors imposes serious real-time cons
traints on the methods used. First of all, fast structure characteriza
tion methods are presented allowing us to track the model structure on
-line. Since these so-called a priori methods are less computing inten
sive, they carl be at the basis of optimal experimental design calcula
tions that can be performed on-line, This allows us to maintain the qu
ality of the overall model identification under the changing process c
onditions of a wastewater treatment plant. Two applications of Optimal
Experimental Design are given.
