In this study characteristics of dynamic filters using Taylor vortices are investigated. Filtration experiments are conducted with silica slurry and filtrate fluxes are analysed on the basis of the Taylor number and the rotational velocity of the membrane filter by dividing them into two regions; the transient state and the pseudosteady state. During the transient period the initial variation of the filtrate flux to filtrate volume is found to decrease linearly with increasing the Taylor number, while the filtrate flux at the pseudosteady state is found to increase linearly with increasing the rotational velocity of membrane. Based on these results, empirical correlations to represent filtration characteristics are provided.
