We investigate a model for an activated sludge process connected to a sludge disintegration unit. We formulate a model for the sludge disintegration unit in which the disintegration processes occur at a finite rate. We then take an appropriate asymptotic limit to obtain a model when these processes occur infinitely quick. We use our limiting model to show that an infinite-rate model proposed earlier in the literature is incorrectly formulated. Our principle aim is to investigate how the disintegration rate in the sludge disintegration unit affects the formation of sludge in the reactor.
