Abstract: A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.

Abstract: An above grate based inlet filter system for erosion and sediment control comprises a filter mat configured to extend beyond the perimeter of the grate and a securing mechanism, such as magnets, configured to securing the filter mat around the perimeter of the grate. The system may include a filter berm secured in vicinity to the mat, and a rectangular array of magnets coupling the filter mat to the grate. The natural fiber filter mat may effectively be formed of vertically aligned coir fibers or alternatively of reticulated foam. Multiple side edges of the mat are undulating having a pattern of repeating recesses. The mat includes a plurality of high flow holes extending into the mat and which are closed at a bottom surface thereof.

The system may include a filter berm secured in vicinity to the mat, and a rectangular array of magnets coupling the filter mat to the grate. The natural fiber filter mat may effectively be a coir fiber filter mat extending beyond the perimeter of the grate, wherein the coir fiber filter mat is formed of vertically aligned coir fibers. The optional filter berm may be effectively formed as triangular in cross section and formed of 100% reticulated polyether foam and formed to be at least 3? in height.

Abstract: A Composite Filter Sock Assembly includes a Compost Filter Sock and Secondary Tubular Seam Filling Device configured to be wedged beneath the compost filter sock, whereby the compost filter sock provides a pinning pressure to the Secondary Tubular Seam Filling Device and wherein the compost filter sock has a nominal diameter of 2-12 times a diameter of a tubular element of the Secondary Tubular Seam Filling Device. The Tubular Element may be least partially filled with a swell-able material such as sphagnum peat moss and may include a fastening mechanism on an exterior surface configured to facilitate coupling to a mesh tube of a compost filter sock.

Abstract: A temporary all plastic erosion control blanket is configured to slow water runoff, to provide sediment and erosion control, and to enhance re-vegetation. The temporary all plastic erosion control blanket is fully degradable within less than one year. The temporary all plastic erosion control blanket is a warp knitted structure formed from polyolefin or polyamide materials and includes integral visual stake placement indicia.

Abstract: A compressed netting sleeve for in situ formation of a compost filter sock comprises a sleeve of netting material having a pair of opposed open ends, wherein the sleeve of netting material is bunched primarily along a longitudinal axis, whereby each of the open ends of the netting material remains accessible to form a compression bundle netting material; and a protective sleeve extending through the open ends of the sleeve of netting material to extend through the interior of the sleeve of netting material and around the exterior of the sleeve of netting material thereby surrounding the compression bundle netting material with the protective sleeve.

Abstract: A compost filter netting comprises plastic netting formed in a tube having a diameter of 6?-36? wherein the plastic netting includes netting openings of ?-?? and configured to be filled with compost to form a compost filter sock, wherein the linear length of the compost filter sock is not less than 93% of the linear length of the originally manufactured empty compost filter netting. A method of forming a compost filter sock using the compost filter netting and the compost filter sock made thereby is disclosed. The compost filter netting substantially eliminates the problem of miscalculation of shrink rate that is problematic for in field applications.

Abstract: A method of forming a vacuum packed compressed netting sleeve for in situ formation of a compost filter sock comprises the steps of: providing a sleeve of netting material having at least one open end; bunching the sleeve of netting material primarily along a longitudinal axis, whereby each open end of the netting material remains accessible to form a compression bundle netting material; placing the compression bundle netting material in a sealable weatherproof bag; drawing a vacuum in the bag to compress the compression bundle netting material; and sealing the bag. A mechanical fastener capable of securing a compression bundle netting sleeve in position may be provided within in the bag. The bag may efficiently store remnants of the netting sleeve at the end of given manufacturing runs.
