An equation was obtained that would establish the growth kinetics under batch conditions in an aerobic system of organic wastes. The growth kinetics equation was then combined with a linear relationship between sludge growth and BOD removal in order to develop a second equation that expressed the BOD removal under batch conditions. The two equations were combined with a mass balance to determine the treatment efficiency in a completely mixed-continuous flow system. The equations thus developed for these two systems (batch and completely mixed-continuous flow) were checked against experimental results obtained with a synthetic activated sludge at 25○C.
