The concept of employing Common Effluent Treatment Plants (CETPs) to collectively treat effluents emanating from a number of industries is assuming rapid significance due to industrialization and expected reduced cost of collective treatment. Modeling of process variables in CETPs is helpful in controlling its dynamic behavior and for predicting plant performances. Determination of real-time data is costly requiring lab and skilled personnel, besides having limitations on measurement of real-time process variables such as BOD. Under such circumstances, process modeling could be gainfully...
