Which Type of Turbidity Curtain
do I use?
Question regarding a turbidity curtain to control silt: Hi there! We're in St. Augustine FL and we're building a bulkhead on a creek. We require about 125 ft of turbidity curtain (x 5ft) to contain potential silt runoff if it rains while we're working. I am not sure which type I need. The water's rate of flow is less than .25 knots.
Answer:
Thanks for contacting Granite Environmental. I'd be happy to help you figure out which type of floating turbidity curtain to control silt you need for your application and how we can help.
If your water flow in less than .25 knots, you should use a Type 1 Silt Barrier. It is designed specifically for silt and turbidity control in calm waters such as swales, canals, small ponds and lakes and harbors. The silt curtain is ideal for use along Roadways for Department of Transportation D.O.T. projects and meet and exceed state requirement.
Our in stock sizes come in 50' or 100' lengths, but we can make the turbidity curtain to the size you need.
Choosing the Correct Turbidity Curtain to Control Silt
Choosing the correct turbidity curtain to control turbidity and silt in your location will depend on several different conditions and factors in your location. Once these factors are considered, barriers can be correctly chosen. The following can be seen as a general guideline on how these turbidity curtains are used:
- Type 1 Turbidity Curtain: This silt curtain is commonly used in locations with calm waters (such as your conditions which is less than 0.25 knots)
- Type 2 Turbidity Curtain: The type 2 curtain is used for moving water locations. These barriers are typically not recommended for locations with currents above 1.5 knots.
- Type 3 Turbidity Curtain: The type 3 curtain is our strongest barrier and is used for the roughest water conditions. These includes areas with significant water flow or waves.
