What material is used to filter sediment-laden water in standard inlet protection?

The correct material used to filter sediment-laden water in standard inlet protection is woven slit film geotextile. This type of geotextile is designed specifically for applications involving erosion and sediment control due to its effective filtration properties. Woven slit film geotextiles are made from slit film fibers, which provide a robust structure that allows for efficient water flow while effectively trapping sediment particles.

In the context of erosion and sediment control, standard inlet protection is used to help prevent sediment from entering stormwater inlets during construction or land-disturbing activities. The woven slit film geotextile allows water to percolate through while capturing sediment, thereby helping to maintain water quality and prevent clogging of stormwater systems.

The other materials listed, while they have their uses in different contexts, do not provide the same level of filtration efficiency and structural integrity required for inlet protection. For example, woven monofilament geotextiles, while effective for other applications, do not typically offer the same filtration capabilities as slit film options. Nonwoven geotextiles may also serve as filtration solutions, but they are typically used in different contexts, such as separation or drainage, rather than directly filtering sediment-laden water in an inlet protection scenario.
