Abstract
This paper contains two contributions. First it is shown, in a simulat ion study using the IAWQ model, that a linear multivariable time-invar iant state-space model can be used to predict the ammonium and nitrate concentration in the last aerated zone in a pre-denitrifying activate d sludge process. Secondly, using the estimated linear model, a multiv ariable linear quadratic (LQ) controller is designed and used to contr ol the ammonium and nitrate concentration.
