|Title:||Continuous Rotating Biological Contactor for Denitrification of Wastewater|
|Keywords:||Civil Engineering;Civil Engineering|
|Abstract:||<p>This work presents the results of a pilot plant study where a completely submerged rotating biological contactor was used for denitrification of domestic wastewater.</p> <p>The literature review emphasizes the existing knowledge on RBC operation and design fundamentals. A brief summary of the theory of denitrification has been presented as this subject already has been presented in detail by various authors.</p> <p>Dye studies were performed for 4 stage series operation and single stage operation. A two CSTR with interchange flow model seemed to fit the hydraulic model for single stage operation. The dye responses was observed to be function of biological growth which in turn varied with temperature.</p> <p>"Zero order" kinetics were shown to represent the data obtained for denitrification rates at hydraulic loadings of 2.5 1/min and 4.0 1/min best for the range of NO3+NO2-N concentrations studied.</p> <p>An energy of activation of 16,500 kcal/mole was calculated for hydraulic loading range of 2.5-4.0 1/min.</p>|
