Abstract
An erosion, sediment and pollution control product comprises a rice hull filler material which has been heat treated sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material; and a containment member containing the rice hull filler material and allowing fluid to flow through the containment member and the rice hull filler material. The containment member is a geotextile which may include cellulose based threads treated to be hydrophobic.

An erosion, sediment and pollution control product comprising:
- A rice hull filler material which has been heat treated sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material;
- A containment member containing the rice hull filler material and allowing fluid to flow through the containment member and the rice hull filler material, wherein the containment member is a tubular mesh member, wherein the tubular mesh member includes cellulose based threads treated to be hydrophobic, and wherein the cellulose based threads treated to be hydrophobic is treated with at least one of mineral oil, beeswax, paraffin, petroleum jelly lanolin and plant based oils.
An erosion, sediment and pollution control product comprising:
- A rice hull filler material which has been heat treated sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material;
- A containment member containing the rice hull filler material and allowing fluid to flow through the containment member and the rice hull filler material, wherein the containment member is a tubular mesh member, wherein the tubular mesh member includes cellulose based threads treated to be hydrophobic, and wherein the cellulose based threads includes lyocell.
A tubular erosion, sediment and pollution control product comprising:
- A rice hull filler material which has been treated sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material;
- A tubular mesh containment member containing the rice hull filler material and allowing fluid to flow through the containment member and the rice hull filler material, wherein the tubular mesh containment member exhibits a fabric flow test of between 100 and 700 Gallons per minute based upon the permittivity test results, wherein the tubular mesh containment member includes cellulose based threads treated to be hydrophobic, and wherein the cellulose based threads treated to be hydrophobic is treated with at least one of mineral oil, beeswax, paraffin, petroleum jelly lanolin and plant based oils.
