Hydraulic Age Distribution

The methodology to study the hydraulic age distribution in steady-state perfectly mixed reactors was established by Danckwerts (1953) in his classic work “Continuous-flow Systems.” But the simple equations developed for the steady-state regime are not applicable to nonsteady-state regimes, which are characterized by irregular hydraulic age distribution. The Leslie Matrix Model was originally developed for the analysis of age structured biological population dynamics. This chapter deals with the application of the Leslie Matrix Model to the “age population” of effluents within stabilization reservoirs as representatives of nonsteady-state flow reactors.
