Abstract: A filtering device for reducing radiation, sediment, contamination, pollution, and erosion control contains a first flow plate, a second flow plate, a tubular portion, and a biodegradable filtering material. The first flow plate is terminally connected to a first end of the tubular portion. A plurality of openings of the first flow plate allows water to enter the tubular portion. The second flow plate is terminally connected to a second end of the tubular portion. A plurality of openings of the second flow plate allows water to exit the tubular portion. The biodegradable filtering material is integrated within the tubular portion so that water entering the tubular portion at the first end is filtered prior to exiting the tubular portion at the second end. Switchgrass is utilized as the biodegradable filtering material.

Abstract: A system and method for manufacturing erosion control filter socks consists of a mass of filtering material, a material supply assembly, an assembly section, and a packaging section. Switchgrass is used as the filtering material. Upon receiving the mass of filtering material, the material supply assembly appropriately transfers the filtering material to the assembly section. The filtering material is loaded into a receiving sock with the use of a sizing funnel in the assembly section to create a filter sock. The density of the filtering material within the filter sock varies. When loading is complete, the packaging section sizes the filter sock accordingly. When sizing the filter sock is complete, the filter sock is wrapped in a plastic cover so that the filter sock can be conveniently transported and installed.
