Optimal artificial aeration design in polluted streams receiving thermal discharge
The optimal artificial aeration scheme for a polluted stream which receives additional thermal discharge is studied. The continuous maximum principle is employed to find the optimal control policy which minimizes the system objective function and maintains an appropriate water quality in the stream. The system objective function which consists of the DO violation penalty from the desired value and the artificial aeration effort increases significantly with increasing amount of thermal discharge in comparison with the isothermal case. The system objective function also increases exponentially with increasing upstream BOD concentration. A design procedure is presented to find the optimal artificial aeration control policy which is able to maintain the water quality at a minimum legal requirement.
