Applying membranes with especial geometries and fouling characteristics has been an area of research and a subject of interest in membrane science community. While a considerable part of fouling happenings are originated from chaotic roots such as Brownian motions, the remainders can be scheduled to approach on desired filtration features. Here in this study the somehow invisible features of progressive fouling which is the case for novel micro-engineered membranes was realized in some details. The problem of progressive fouling was considered as a result of dead-ended filtration of non-colloidal particles over a vertically extended pore geometry. It was shown that, in this filtration apparatus, due to a serialized activation and deactivation of flow passages, progressive fouling can change its seat with other more flow resistive classical types of surface and pore blockings and control filtration path more apparently. Results was considered for different amounts of pore extension and porosities. It was found that employing an especial set of pore extension length and porosity make it feasible to derive manageable filtration processes with high levels of purification and permeation performances.
