| Abstract | The models developed in this study can be used as guidelines for design of small treatment plants employing completely mixed activated sludge process without having the need to conduct pilot plant investigation which is costly. The study is an attempt to quantify the relationship between BOD5/COD and the substrate removal rate coefficient, k, defined in the modified Eckenfelder model. Also included in the study is the correlation of influent organic concentration, S0 versus detention time, t. The operating data of 17 full scale, 3 pilot scale, and 9 bench scale studies on completely mixed activated sludge process which were taken from literatures were used in the regression analysis. Values of k were recalculated to a standard temperature of 30°c. Regression analysis reveals strong relationship exists between the above-mentioned parameters having level of confidence of 95 percent. Applications of the models how that comparable design estimates can be achieved to that of the actual design. Recommended models to be used are: |
