Turbidity Barrier And Silt Curtain Info

Silt and Turbidity Control Barriers

turbidity barrierThe turbidity barrier, also known as a silt barrier or turbidity curtain, is a device designed to contain suspended materials such as sediment, silt, and turbidity. Built with a long bottom curtain, these control barriers have been used in locations across the world to keep materials from polluting the surrounding area.

How Does a Turbidity Curtain Work?

The design of a turbidity curtain or barrier allows it to operate extremely similar in style to a containment boom or barrier. The main difference is that instead of containing a short skirt, these products will have a long skirt that extends down anywhere from three to one hundred feet (3' to 100'). This provides containment both on the surface and well underneath the water.

When installed in your location, barriers will typically work to form a containment area around your construction job, dredging operation, cleaning or repair job, or any other area where materials are being displaced or polluted. As these materials are turned up, dredged, or produced, barriers will work to keep them well within a certain area.

Turbidity Curtains Help To:

  • Contain Pollution
  • Prevent Sediment Spreading
  • Increase Sediment Settling Times
  • Lower Water Pollution Levels
  • Protect Wildlife

How Do I Choose the Right Floating Turbidity Barrier?

Choosing the right floating turbidity or silt barrier will often depend largely on your specific site, job requirements, and water conditions. The following can be used as a general guideline, although these barriers and curtains are often chosen based on many additional factors such as job type, sediment containment requirements, and project duration:

  1. Type 1 Silt Barrier: Calm Water Applications (Economy or DOT)
  2. Type 2 Silt Barrier: Medium-Water Conditions (max 1.5 knots, 3 foot waves, knots not above 1.5, waves not above 3 feet) (Medium Duty or Heavy Duty)
  3. Type 3 Silt Barrier: Rough Water Conditions (Medium Duty or Heavy Duty)

When Does Dispersion of Sediment, Silt and Turbidity Happen?

We all know road work construction when we drive on highways or turnpikes. Turbidity barriers are typically used for construction work that you may not usually see, such as marine construction work, dredging activities, or pile driving and stormwater sheet flow. A lot of these projects occur in water bodies, although some can occur directly on a site.

Whenever silt or turbidity is mixed into a water flow, a floating turbidity or silt barrier can be used to contain these materials and keep them from polluting an area. For more information on these containment and pollution control devices, please check out our Turbidity Barrier Main Page.
