The submerged pleated filter with bubble jet function was developed and the constant rate filtration experiment of cornstarch suspensions was carried out at different filtrate flow rates and particle concentrations. In contrast to dead-end filtration without bubble jet in which the pressure rises remarkably, the pressure rise is suppressed by removal of the filter cake in filtration with bubble jet, leading to an equilibrium value. Thus, the proposed filtration system is useful as one of the dynamic filtration modes. Moreover, the partial dynamic filtration model was established and as a result the experimental data could be well described by this model. The model analysis clearly demonstrated that the filtration performance was determined by a product of the filtrate flow rate and the particle concentration, i.e., the feed rate of particles. Also, it was revealed that the maximum ratio of cake-exfoliated area of the pleated filter used in this study was 0.65.
