Evaluation of Alternative Unstructured Kinetic Models for Simulating the Dynamics of the Activated Sludge Process

Four unstructured kinetic models were used for simulating the transient response of the conventional activated sludge to shock loadings. The aeration tank was assumed to be a continuous stirred tank reactor while the settler dynamics were simulated as a simple first order lag. Parameter identificati...
