Double filtration tension frame sediment control filter
A double filtration sediment control device to improve sediment removal from stormwater. A sheet of filtering geotextile is sewn to form a sleeve and a leading flap. An elongated flat, flexible frame is bent longitudinally to form an arch that is inserted into the geotextile sleeve. After insertion, the frame expands against the sleeve to support the sleeve in an arched orientation with an uphill leg and a downhill leg. The outside of the uphill leg is a first filtering surface, and the inside of the downhill leg is a second filtering surface. The flap is covered with soil to direct water through the device, and the device is anchored with sod staples driven through the flap. The frame provides a height and functional rigidity to the assembly. The second filtering surface may be a finer filter than the first filtering surface.
