<p>The capacity and operating time of a solid particulate filter of honeycomb construction may be increased by forming the filter with a matrix of thin, interconnected walls which define a multiplicity of cells and which have interconnected open porosity of a volume and size sufficient to enable the fluid to flow completely across the thin walls in their narrow dimensions between adjoining cells and through the thin walls in their longer dimensions between adjoining or neighboring cells and to restrict the particulates in the fluid from flowing either completely across or through any of the thin walls and by dividing the cells into an inlet group and an outlet group and providing the inlet group of cells with substantially greater collective thin wall surface area than is provided to the outlet group of cells.</p> |
