Silt Barriers Help Contain Turbidity During Dredging Projects
Silt barriers, also known as turbidity curtains or turbidity barriers, can be placed around dredging areas to help contain turbidity that occurs as a result of dredging activities. These barriers have been used to help prevent dredging projects from polluting water areas.
- (1888PressRelease) January 13, 2012 - With hundreds of dredging projects in effect in locations across the world, the need to create a safe dredging process has dramatically increased.
Dredging typically refers to the process of digging up sediment and sand materials in locations under the water and then placing those materials into new locations. Sediment and sand excavated during this process can be placed back along eroded shores, in construction locations, or in various other places requiring additional support. Dredging has also been frequently used to remove sediment build up that has caused blocking of water passages or other navigation areas.
During the dredging process, there is often an increase of turbidity and other toxins that can cause an adverse effect on surrounding plant and wildlife. In order to keep these effects under control, items such as the turbidity barriers and dewatering bag can be used to contain turbidity and help filter sediment laden water.
The turbidity barrier, also known as the silt barrier or silt curtain, is a frequently used containment system that has been placed in rivers, lakes, oceans, and along shore lines to control turbidity that can build up during a construction, dredging, pile driving, or marine construction projects. These barriers include foam flotation devices that are sewn into the top of the barrier to providing protection above the surface, and steel ballast chains that are installed into the bottom of the barrier to help sink the barrier skirt and contain turbidity to a specific area. This can be especially important in dredging activities as it helps contain increased turbidity in your dredging area for the duration of your project.
In addition to these barriers, control products such as the dewatering bag or dewatering tube can help clean out sediment-laden water and keep these materials firmly inside the bag for later placement. This serves the dual purpose of cleaning out silt from the water, while also providing a way for dredged silt to be stored and contained.
According to Mark Wilkie, President of Granite Environmental, "To keep your water conditions under their Total Maximum Daily Loads (TMDL) during the dredging process , turbidity curtains and silt barriers are the most economical option. When used correctly, these barriers can effectively prevent water pollution through silt and turbidity. For every water condition, wave height, and current strength, different barrier types are available to perform accordingly to the EPA regulations. Our barriers are available as stock items in fifty and one hundred feet sections or custom built. We can provide any turbidity curtain needed to finish dredging projects successfully."
Helping to address all your dredging requirements, Granite Environmental Inc. works to supply innovative products to help control and manage your dredging location while it's in operation.
