How Silt Socks Work
The Working principle of silt socks is based on the concept of filtration and sedimentation. As water flows through the sock, the geotextile material allows the water to pass through while trapping the sediment and silt. The filtering medium inside the sock helps to remove smaller particles and contaminants, resulting in cleaner water. The process can be broken down into several stages:
The water enters the sock through the inlet, carrying sediment and silt with it.
The geotextile material filters out the larger sediment particles, allowing only smaller particles to pass through.
The filtering medium inside the sock captures the smaller particles, removing them from the water.
The clean water exits the sock through the outlet, leaving the sediment and silt behind.
