Floating Turbidity Barrier

Turbidity Control with Floating Curtains and Barriers

floating turbidity barrier

Question: I have been required to use a floating turbidity barrier on my site for turbidity control and to help contain silt that is being churned up as I build my dock. I have been researching the best options for my site and am interested in knowing the difference between the barriers, as well as when would be a good time to use impermeable versus permeable.

Answer: The floating turbidity curtain, also referred to as a turbidity barrier, is a floating containment device designed to offer turbidity control and contain silt stirred up due to dredging, construction, or other maintenance work in the area.

Floating Turbidity Barrier Design

Our floating turbidity barriers are available in three different models: Type 1, Type 2, and Type 3 Curtains. Types are designed to go up in strength for turbidity control, meaning that the Type 1 is equipped for calm or even water locations and the Type 3 is built for demanding conditions. All turbidity curtain types are typically equipped with the following components:

  • Top Flotation Device
  • Universal Section Connectors
  • Grommet Section Ties
  • Steel Ballast Chain
  • Impermeable Skirt

Floating Turbidity Barrier Depths

A floating turbidity barrier's depth is determined based on the depth of the water in your location. Typically you will not want the barrier to touch the bottom of the river, but rather sit at a height of approximately one foot from the floor of your location.

When a floating turbidity barrier touches the bottom of the floor, it runs the risk of getting bogged down or trapped with the sediment that is being contained. This can inhibit the turbidity control, causing floating turbidity barriers to collapse or incur too much pressure during the containment process.

Turbidity Control with Permeable Floating Barriers

While a majority of our turbidity barriers are made with an impermeable fabric, some Permeable Filtering Barriers have been made in areas that have an increased water velocity. This can help to additionally relieve pressure placed on the barrier in extreme conditions where turbidity control is needed.
