ETP-I Turbidity Curtain

ETP 1 Turbidity Curtain

ETP 1 Connected


The ETP-I is best used for small ponds, small lakes, and areas without strong currents and high winds.  This is an excellent choice for a sea wall.  It is very light and is easy to deploy and adjust as needed without heavy equipment.  This curtain is made so that a very fast deployment can be achieved with a minimum amount of labor.  ETP-I consists of a top flotation and a light ballast sealed inside the curtain.

The curtains are normally manufactured in 25-foot sections.  The connection of multiple sections is made by a heavy-duty marine grade rope laced thru heavy duty brass grommets.  The connection points allow the use of wooden or steel stakes for additional stability in longer sections.

 

ETP-II Turbidity Curtain

ETP II Separate

ETP II Connected

The ETP-II is best used for ponds, lakes, bays, rivers, and streams.  This is an excellent choice for a sea wall, around docks, boats, construction sites and a quick temporary response to spill sites.  It is s medium duty curtain made with a heavier fabric than ETP-I and is easy to deploy and adjust as needed without heavy equipment.  This curtain is made so that a very fast deployment can be achieved.  ETP-II consists of a top flotation and a heavier ballast sealed inside the curtain, and a cable sealed in a pocket along the top of the curtain.

The curtains are normally manufactured in 25-foot sections.  The connection of multiple sections is made by using a stainless-steel connection plate at the top and heavy-duty marine grade rope or heavy-duty plastic zip ties laced thru heavy duty brass grommets.  The connection points allow the use of wooden or steel stakes for additional stability in longer sections and concrete anchor or boat anchors may be attached to the ballast to assist with keeping the curtain in position if required.

 

ETP-III Turbidity Curtain

ETP III Not Bolted together

ETP III bolted

The ETP-III is best used for lakes, rivers, bays, and open water applications.  This is an excellent choice for a sea wall, around docks, boats, marinas, construction sites, and spill sites.  It is a heavy-duty curtain made with a heavier fabric than ETP-II and is easy to deploy and adjust with some heavy equipment and boats.  This curtain is made so that a fast deployment can be achieved.  ETP-III consists of a top flotation and a heavier ballast sealed inside the curtain, and a cable sealed in a pocket along the top and 18” below the floatation.

The curtains are normally manufactured in 100-foot sections.  The connection of multiple sections is made by using a stainless-steel connection plates and bolts sandwiching the two sections together. In addition to the heavier ballast for additional stability concrete anchors or boat anchors may be attached to the ballast to assist with keeping the curtain in position in the presence for wave action and higher winds.
