Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In this study an adaptive carbon flow rate controller is applied to a pre-denitrifying pilot-scale plant. The goal of the control strategy is to maintain a low nitrate concentration in the anoxic zone by controlling the external flow rate of the carbon so

-
Recension (övrigt vetenskapligt/konstnärligt)abstract
- In this paper a software sensor for estimating the respiration rate and the nonlinear oxygen transfer function K(L)a is presented. The respiration rate and the oxygen transfer function were estimated from measurements of the dissolved oxygen concentration

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This paper contains two contributions. First it is shown, in a simulation study using the IAWQ model, that a linear multivariable time-invariant state-space model can be used to predict the ammonium and nitrate concentration in the last aerated zone in a

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Control of the dissolved oxygen concentration (DO) in an activated sludge process is of considerable importance because of economy and process efficiency. A strategy for designing a nonlinear DO controller was developed. The basic idea was to take the non
