Abstract


  • We consider a model to describe the performance of a membrane-coupled anaerobic

    fermentor which was developed and calibrated using experimental data by Kim and

    Chung (2010). The model consists of six differential equations, modelling the

    concentration of five biochemical species and the rate of gasification. In the original

    work it was assumed that reactor is well-mixed. We use a two parameter mixing model

    to investigate the effect of incomplete mixing upon the performance of this process. The

    parameters in the mixing mode are the size of the stagnant region ( ) and a parameter

    controlling the degree of mixing between the regions ( ). Perfect mixing corresponds

    to the limit in which delta approaches infinity. There are six differential equations in

    each region.

    We investigate how the concentration of volatile fatty acids in the agitated region

    depends upon the degree of mixing in the reactor and the size of the stagnant region.
