A sediment and pollution control product includes an erosion, sediment and pollution control product filler material, wherein the filler material includes rice hulls and a performance improving material including at least one of i) a carbon material processed to increase the surface area available for adsorption or chemical reactions, ii) peat fibers, iii) kenef material and iv) a aluminosilicate mineral; and a tubular mesh member geotextile containing the filler material, wherein the tubular mesh member exhibits a fabric flow test of at least 100 Gallons per minute based upon permittivity test results in a ASTM 4491 type C testing protocol, wherein the filled tubular mesh member and filler material is configured to allow fluid to flow through the mesh member and the filler material.

A method of assessing a membrane includes calculating fluid dynamic characteristics of at least one of a membrane and a material to be passed through the membrane, the membrane includes a plurality of rows and a plurality of teardrop structures arranged in the plurality of rows, the material includes particles; obtaining characteristic of at least one force acting on the particles of the material to be passed through the membrane due to the interaction between the particles and the membrane, the at least one force being an intermolecular force; and combining the calculated fluid dynamic characteristic and the obtained characteristics to assess the flow of the material through the membrane. In some embodiments, the teardrop structures in each row are arranged at substantially the same angle with respect to an anticipated direction of flow through the membrane.
