Floating Turbidity Barriers also know as Floating Turbidity Silt Curtains, consist of a top flotation boom, an impervious fabric curtain extending downward under water, and a heavy galvanized steel chain sealed into a hem along the entire bottom of the curtain to provide ballast to keep the curtain vertical in the water. End hems are sealed around a rope and grommeted to allow attachment to each other with rope or bolt/nuts/washers. Color is Tough Guy Yellow. Type III DOT Floating Turbidity Barriers is a special adaption of the Type III Floating Turbidity Barriers. Approximately 20 % of the area of the barrier skirt fabric is replaced with a polypropylene filter fabric conforming to some State DOT specifications. The filter fabric is inserted to reduce the pressure on the curtain while retaining silt. In actual practice, a filter fabric which is woven tightly enough to retain silt will not significantly reduce pressure on the curtain. Conversely, if the filter fabric is woven loose enough to reduce the pressure on the curtain, it will not be able to retain most silt and sediment particles. In addition, the filter fabric cannot be heat-sealed, and must be sewn into the curtain, resulting in a reduction in curtain strength and longevity.
