Abstract: | The objective of the work presented is to define the hydrodynamic conditions of Dissolved oxygen (DO) consumption by biomass in order to understand their importance on the proliferation of cells responsible for biodegradation of tributary pollutants. Modeling by adimensional analysis proves to be a crucial tool in the prediction of the K L a transfer coefficient that will allow us to make a temporal follow-up. The results showed that K L a decreases with the proliferation of biomass. The consumption of oxygen is present in the process of purification of the fact that Dissolved oxygen constitutes one of the vital substrates to biomass. A global model, derived from dimensional analysis, is proposed for the prediction of the transfer coefficient and mixed liquor of volatile suspended solids (MLVSS) at 26 °C only applies in ranges where the concentration of Dissolved oxygen varies between 4.08 and 6.15 mg O 2 / L... |
