Rotary filter, which avoided the cake sedimentation in the solid-liquid separation by Taylor vortex, was devised. The aspect ratio is less than 3 in the vortex generator, and the effect of the top and bottom boundary edge is not negligible. The alumna particle of 100μm was used as removed material as well as the tracer for the flow visualization. Vortex mode in the test of the rotational filter was the normal 2 cell mode, and the penetration flow rate was constantly to be 180ml/min. Reynolds number is varied from 100 to 600. Cake amount of sediment on the filter surface greatly decreased in Re>500,it remarkably observes the effect of the Taylor vortex.
