Analysis of the activated sludge model (number 1)

Journal Article


Abstract


  • We analyse a model for the activated sludge process occurring in a

    biological reactor without recycle. The biochemical processes

    occurring within the reactor are represented by the activated sludge

    model number 1 (ASM1). In the past the ASM1 model has been

    investigated via direct integration of the governing equations. This

    approach is time consuming as parameter regions of interest (in terms

    of the effluent quality leaving the plant) can only be determined

    through laborious and repetitive calculations. In this work we use

    continuation methods to determine the steady-state behaviour of the

    system. In particular, we determine bifurcation values of the

    residence time, corresponding to branch points, that are crucial in

    determining the performance of the plant.
