Abstract: Structural supports for elements, particularly supports for filtration materials and membranes, and methods of manufacturing such supports are disclosed. The membrane support structure includes one or more tapered through-holes that enable a much larger area of the membrane to be exposed to fluid flow, thereby enhancing separation processes and membrane efficiency. In addition, through-holes having smaller openings on one side of the structure produce improved support and mechanical stability/rigidity. Thus, the structural support increases the surface area of the membrane through which filtration may take place, yet preserves the mechanical strength and stability of the support structure.
