Frog Environmental - Silt Bubble Barriers
Bubble Curtains are used in rivers and other water bodies to help control silt movement and reduce the risk of silt pollution created by construction activities. Working on or near water stirs up the silt from the bank or beds of watercourses like rivers, lakes, lochs or canals. Silt can be carried in the water column for some distance before being re-deposited as sediment, and can cause negative environmental impacts downstream, resulting in silt pollution.
Often deployed downstream of temporary works in waterways, the clever Bubble Tubing® technology can act as a barrier to reduce the movement of disturbed sediment and silt.
Silt plumes can also lead to an increase in oxygen demand which in turn can put stress on fish and other animals. The micro-bubbles created by the tubing deliver an oxygen rich environment without the use of chemicals.
Bubble Curtains tend to be weighted to the floor of the waterbody to create a consistent flow of bubbles across the entire water column for highly effective silt control and emergency aeration.
Bubble Barriers are also used to help control oil spills, litter and weeds or protect assets from abstraction.
Please contact us if you need help with pollution control or aeration.
