Practical application of Wu's model for the prediction of soluble BOD removal in RBC systems is discussed extensively for various operating conditions. The model was tested by the use of more than 80 data sets obtained from the operation of six full-scale RBC plants. Also, nomograms were constructed to demonstrate a method for selecting the design surface hydraulic loadings. More importantly, the hydraulic loading rates predicted/calculated on the basis of the criteria employed for four full-scale RBC plant designs were compared with the actual design hydraulic loadings. No significant difference between the predicted and the designed hydraulic loading was found.
