![]() Very resistant, reusable and ecological, bubble curtains act as sediment barriers and also allows for an increase in the level of dissolved oxygen in the water – a good solution to provide a certain level of mitigation during work or impact on the marine environment!īubble curtains have also been shown to be effective in preventing the discharge of sediment from rivers rich in mineral alluvium to areas without current, such as dead end sea entrances or canals. Specific designs and configurations are created by the Bubble Tubing® team. These bubble barriers, whether single or double (or even triple in certain specific cases for the management of very fine sediments), are easily set up at different depths and in different types of marine environments such as seaports, rivers, bays, lakes and reservoirs. This efficient method facilitates maritime transport in several types of industrial applications. Installing a retention curtain like the one from Bubble Tubing® is an effective solution to contain sediment and prevent the water from becoming cloudy outside of maritime work areas. Also, during dredging, opening these barriers releases a large amount of suspended matter.īy using a bubble curtain combined with a physical barrier, an opening is created which will allow free passage and which can also retain suspended sediments during the activities. The physical barriers have one main fault, they are fixed and cannot allow the free passage of boats or living species. What is less known is the use of a bubble barrier as a complement to physical barriers. ![]() ![]() These techniques are well known and implemented throughout the world. They allow the retention in place of fine materials that can be dangerous for the aquatic environment and which can, for example, cover spawning grounds or modify the fragile habitat of aquatic species. These materials are often retained by physical barriers called sediment barriers. Typically during dredging or maritime works, there is a dispersion of suspended matter in the water.
