Model Type I -Turbidity Curtain
Type 1 turbidity curtain is a type of marine barrier designed to control the spread of silt, sediment, and other particles in the water. These turbidity curtains are built with foam-filled floats that are referred to as Freeboards, combined with skirts that typically range in height from 3 to 20 feet. These floating silt curtains impede the flow of silt or sediment that may be suspended in the water. Type I turbidity curtains are typically used in calm waters with limited wind exposure, making it suitable for use in ponds, lakes, canals, streams, ditches, bayous, swamps, and other protected waters. These can be constructed to meet DOT upon request. All curtains can be fabricated with permeable or impermeable skirts, which determines whether water can pass through the skirt. Permeable Type I Turbidity Curtains: Made of a geotextile fabric that allows water to flow through the curtain while still filtering any suspended silt or sediment.
Impermeable Type I Turbidity Curtains: These silt curtains are made with the same PVC fabric that is used for the floats. This fabric does not allow water to pass through, creating a barrier that fully blocks the water and any silt or sediment that may be suspended in the water.
