For the activated sludge process the principles of microbiological growth in continuously fed systems must be combined with materials balance and unit process concepts to provide a fundamental basis - a basis that should allow the rational development of effective design parameters and operation procedures as well as the accurate prediction of process performance. Using this rationale, the investigation first developed a mathematical model describing the activated sludge process for steady and transient state conditions and then tested the model under laboratory and pilot-plant conditions.
