The average sludge age (c) of the activated sludge process (ASP)‐biofilm were developed and verified experimentally. In addition, the stability and safety factor were investigated against c through a series of curves. These curves are important to explain, in concept, the function of the hybrid system under different values of c. The proposed curves of this study are simple and can be modified for any specified wastewater. The definition of c of ASP was found to be applicable to the hybrid system after including the biofilm. A ratio ranging from 70 to 80% of the total mass of biofilm may be used in the definition of c to give close results with the experimental values. Furthermore, the minimum sludge age (M c ) does not exist in the hybrid reactor because of the presence of biofilm; however, c should come down to a critical value under some specific conditions of the reactor.
