The research trend of numerical simulation of microfiltration (MF) of particles and its features after 2007 are reviewed. In the around early 2000s, it became possible to perform Direct Numerical Simulation (DNS) that solves the behavior of multi–particles coupled with particles and fluid motion. In the field of MF simulation, a number of simulation studies with a large number of particles have been tried. With the introduction of interaction between particles or between particle and membrane, it became possible to understand qualitative trend and important factors in MF. On the other hand, the fouling time of membrane in the actual scale has not been understood yet. Therefore, the important issue in the future is the scale–up of meso–simulation.
