A new model for the simulation of biological processes of carbonaceous substrate and nutrient removal has been developed for steady-state conditions. This paper reports the results of a first validation of this model on a pilot-scale plant. The pilot plant, with a University of Cape Town ?UCT? configuration, was operated for 100 days with a high sludge age and was fed with raw sewage, with a significant fraction of industrial effluents and with a strong variability in organic and nutrient loads. The comparison between the experimental results and the calculated ones showed a good fitting. The variations in the influent organic concentration made it difficult to reach steady-state conditions. Nevertheless, the results showed that, as the experimental period was longer than three sludge ages, the experimental data closely approached those calculated with the model.

Abstract
A new model for the simulation of biological processes of carbonaceous substrate and nutrient removal has been developed for steady-state conditions. This paper reports the results of a first validation of this model on a pilot-scale plant. The pilot plant, with a University of Cape Town ?UCT? configuration, was operated for 100 days with a high sludge age and was fed with raw sewage, with a significant fraction of industrial effluents and with a strong variability in organic and nutrient loads. The comparison between the experimental results and the calculated ones showed a good fitting. The variations in the influent organic concentration made it difficult to reach steady-state conditions. Nevertheless, the results showed that, as the experimental period was longer than three sludge ages, the experimental data closely approached those calculated with the model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
