Comparative analysis of the flow and filtration capabilities of sediment retention devices-Part 2

a safety hazard on adjacent roadways. As
noted earlier, D5141 effectively quantifies
the sediment removal effectiveness and
the associated sustained seepage of the
filtration component of an SRD (Figure
2), while D7351 quantifies the balance of
sediment removal and sustained seepage
for the installed SRD system.
ASTM D5141 test data
Figure 3 presents results of ASTM D5141
testing of a wide range of SRD types commonly used in linear, toe-of-slope applications. SRDs tested include both woven
and nonwoven geotextile-based silt fence,
as well as various proprietary composite
and woven fences and socks/wattles.

Discussion of D5141 data
Figure 3 also shows a clear delineation
between product types and their relative
performance in both filtration efficiency
and flow rate. This data is comprised of
six nominal categories of products tested
using ASTM D5141. The nominal categories, as identified by the authors, and the
numbers of tested products are as follows:
*	 32 woven slit film geotextile silt fence
*	 6 woven monofilament geotextile
silt fence
*	 5 nonwoven geotextile silt fence
*	 8 nonwoven composite geotextile
silt fence
*	 5 three-dimensional filter socks
and fibrous wattles
*	 6 proprietary woven geotextile
silt fence
Woven slit film geotextile silt fence
Since it is the category of SRDs tested
most frequently using test method ASTM
D5141, there is a wealth of valuable comparative data about SRD filtration components composed of woven slit film
geotextile silt fence. It is apparent from
the data that this category of filtration
component provides excellent filtration
efficiency across all tested products. All
