Abstract
The computer program (FORTRAN, IBM 1130) simulates the time-dependent behavior of the biological aspects of the activated sludge process. Generally accepted relationships for biological activity are used. The program numerically integrates the mass balance and biological rate equations which are assumed to represent the process. Three classes of microorganisms are considered: heterotrophs, nitrosomonas and nitrobacter. This mathematical model has been used to investigate a number of schemes for automatic control of the activated sludge process. (Author)
