Silt Curtain
A Silt Curtain is a permeable or impervious construct placed in the water columns that is used to restrict the movement of aquatic silt. The purpose of a silt curtain, also referred as a turbidity curtain, flotation curtain, or silt screen, is to confine disturbed material around one to two meters from the edge of the water.
Managing dispersion permits dispersed material to rest and fall within the water column. The climate and time required for dispersed sediment to sink to the bottom are provided by a silt curtain.
Applications of Silt Curtain
Silt Curtains are used to limit the movement of dispersed silt and sediments into water courses surrounding civil operations in or near waterways. Curtains are designed to suit a variety of canal situations, with the goal of allowing distributed silt or sediment to settle and sink to the bottom.
This is used to limit the movement of suspended silt and sediment and to assist localized settling. Its purpose is not to generate a filtering media, but to establish a regulated confinement region where settling may take place.
Flow velocity, depth of water, circumstances, and project length are all key aspects to address while constructing and building a Silt or sediment Curtain.
Prominent applications of Silt include:
- Building or repairing a bridge
- Building or repairing a rock wall
- Construction or restoration of jetty
- Civil works around or in the vicinity of waterways
- Dredging on the coast or in the sea
- Excavation
- Maintenance of sediment ponds
- Dredging of tailings reservoirs
Benefits of Silt Curtain
- UV-resistant substances
- Oil resistant and crumble free closed cell flotation
- Nonwoven geotextile with a pore size of 90 microns and a high flow rate
- Zipper and ASTM Z-connectors make handling and managing a breeze
- For further stability, reinforce the webbing that runs over the curtain
- Elevated quality and durable components
- Customizable to meet the needs of the situation
- Depths of up to 20 meters are accessible
- Handles and equipment for quick deployment
- Assistance for the entire product
What is the procedure for installing a silt curtain?
It is vital to remember that the goal is not to entirely seal the construction area throughout the whole level of the water column, yet rather to arrange the curtain so that particulates in suspensions disperse as little as feasible further than the screen.
Any debris churned up in the water will naturally return to the sea bed (or river bed), and the farther we are from the mechanical action, the less dirt there will be in the water. As a result, the silt does not require to come into touch with the seabed, because the sediments that may likely go the farthest are those closest to the water’s surface.
In fact, we suggest leaving a space of at least 50 cm between the bottom of the silt curtain and the sea bed to avoid the curtain becoming entangled in the seabed and causing harm. If we employ a very deep silt or sediment curtain, the waters must be very calm; otherwise, the silt or sediment curtain would tend to drift upwards, which will be detrimental to our attempts to confine suspended objects.
It is also worth noting that the larger the floating piece on the surface is, the deeper the silt curtain is. Silt or sediment curtains are available in a variety of depths, ranging from 2 to 6 meters, depending on the depth of the water in which they are employed. If the seas are quite deep, the silt barrier does not have to have the same depth.

FAQ
Silt curtains are devices that control suspended solids and turbidity in the water column generated by dredging and disposal of dredged material. Consequently, silt curtains are considered an integral and necessary part of the regulatory strategy for many dredging projects.
The silt curtain shall be removed by pulling it toward the construction area to minimize the release of trapped sediment. Both the top and bottom lines shall be pulled together like a parachute to pull the sediment ashore.
Conclusion
The usage of a silt curtain as a form of environmental mitigation can provide favorable results. Factors linked to operational operations as well as site-specific environmental factors must be considered to achieve a beneficial result. The suitable arrangement of the silt curtain for the specific environment must be chosen in order to obtain maximum performance.
