STC Silt & Turbidity Curtain 05

New Naval's STC Series Silt & Turbidity Curtain Boom provides turbidity control and contains suspended silt, marine litter, floating pollutants or organisms such as jellyfish that can be detrimental to surrounding environments. An impermeable silt curtain holds suspended silt and allows silt to settle in a controlled and current limited environment. The boom is ideal for highly erosional locations where sediment run off or storm water pollution can cause damage or distress to delicate environments and ecosystems. The boom is practical for construction or marine repair projects where sediment run-off and disturbances must be regulated and contained.


•  A submerged, impermeable curtain up to 15 m in length is specifi cally designed to contain silt in high turbidity waters
•  The boom is manufactured from high visibility PVC coated PES fabric using High Frequency Thermal Welding
•  The boom configuration is maintained by cylindrical floats placed the boom, made of closed-cell PET foam
•  Enforced axial tension is provided by two tension members; enclosed PET webbing on the top of the boom and a Hot-Dipped Galvanized (HDG) Chain on the bottom of the boom creating a balanced distribution of weight and structure
•  STC Series boom are produced in compliance with US DoT Specifications
